RFC 2206
RSVP Management Information Base using SMIv2
RFC 2206: RSVP Management Information Base using SMIv2 🎀
okay bestie, RFC 2206 is a Standards Track doc from September 1997, and it's all about the RSVP MIB (a management info base) written in SMIv2 🦋 It was written by F. Baker (Cisco Systems), J. Krawczyk (ArrowPoint Communications), and A. Sastry (Cisco Systems). The header doesn't list anything it obsoletes or updates, so it's a standalone glow-up 💅
Status of This Memo 📜
okay so this doc is an Internet standards track protocol for the Internet community, and it's asking for discussion and suggestions for improvements 💖 For the current standardization state and status, check the "Internet Official Protocol Standards" (STD 1) doc. Distribution of this memo is unlimited, so share it with everyone 🌸
Abstract ✨
this memo defines a chunk of the Management Information Base (MIB) for network management protocols in TCP/IP-based internets 🧚 The main point is that it defines objects for managing the Resource Reservation Protocol (RSVP) inside the interface attributes from the Integrated Services Model. So the Integrated Services MIB is directly relevant to this one and cross-references it 🔥 Comments go to the RSVP Working Group at rsvp@isi.edu 💌

the SNMPv2 Network Management Framework is made of four major components 👑 They are:
- RFC 1441, which defines the SMI, the mechanisms for describing and naming objects for management purposes 🌈
- STD 17, RFC 1213, which defines MIB-II, the core set of managed objects for the Internet suite of protocols 💜
- RFC 1445, which defines the administrative and other architectural aspects of the framework 🍓
- RFC 1448, which defines the protocol used for network access to managed objects 🫶
the Framework also lets people define new objects for experimentation and evaluation, which is so fun 🧪
1.1. Object Definitions 🔍
managed objects are accessed through a virtual information store called the Management Information Base, or MIB 💖 Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) that the SMI defines. Each object type is named by an OBJECT IDENTIFIER, which is an administratively assigned name 🎀 An object type plus an object instance uniquely identifies one specific instance of the object. For human convenience we often use a text string, called the descriptor, to refer to the object type 🦋
2. Overview 🌸
2.1. Textual Conventions 🧁
several new data types get introduced as textual conventions in this MIB document ✨ These make the spec easier to read and can make it easier to compare with other specs when that fits. Here's the important bit: adding these textual conventions has no effect on the syntax or the semantics of any managed objects 🙈 They're just an artifact of the explanation method. Objects defined with them are always encoded using the rules for the primitive type. So no changes to the SMI or SNMP are needed to support them. They're there purely for readers and writers chasing clear, concise, unambiguous MIB docs, which is the elusive goal, honestly 💅
2.2. Structure of MIB 🗺️
the MIB is made up of these sections:
General Objects
Session Statistics Table
Session Sender Table
Reservation Requests Received Table
Reservation Requests Forwarded Table
RSVP Interface Attributes Table
RSVP Neighbor Tableokay so here's the general rule 🧠 It's hard in SNMP to describe arbitrarily long or complex messages, so this MIB describes the Path State Database and the Reservation State Database as if each flow and filter description in an aggregate message had arrived in its own separate reservation message. It's giving clean and organized 🌈
For example, say a RESV message comes in for session 224.1.2.3+UDP+4455 with two filter/flow spec groups, one describing sender 1.2.3.4 and another describing sender 1.2.7.8. The MIB shows these as two separate rows: one for 224.1.2.3+UDP+4455 from 1.2.3.4, and one for 224.1.2.3+UDP+4455 from 1.2.7.8 🦋
2.3. Semantics of Writing the Path and Reservation State Databases ✍️
the path and reservation state tables are writeable 🔥 Writing into the Path and Reservation State databases lets you make RSVP reservations without going through RSVP's own authentication. Instead you authenticate through SNMP mechanisms 💀 State created this way by SNMP doesn't time out, and it can't be deleted by receiving an RSVP teardown message. It can only be deleted by SNMP. To delete it, write destroy to the associated Row Status object. That also triggers a teardown message, as if the state had timed out 🫶
2.4. Intended use of Flow Notifications 📣
2.4.1. The lostFlow Notification 📉
the Lost Flow notification is an asynchronous event that signals a flow is no longer being observed 😭
2.4.2. The newFlow Notification 📈
the newFlow Notification defined in this MIB can be used to tell a network management system about the state of a flow 🧚
3. Definitions 💜
okay bestie, the MIB module is where the actual data structures live, so pay attention 💅✨

INDEX { ifIndex }
::= { rsvpIfTable 1 }okay bestie, we're picking up with the interface table 🦋 RsvpIfEntry is basically each interface's settings card, so let's go through the knobs one by one 💅
RsvpIfEntry ::=

}First up are the neighbor counters 🌸 They're all read-only, so you can look but not touch 👀
rsvpIfUdpNbrs OBJECT-TYPE
SYNTAX Gauge32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of neighbors perceived to be using
only the RSVP UDP Encapsulation."
::= { rsvpIfEntry 1 }
rsvpIfIpNbrs OBJECT-TYPE
SYNTAX Gauge32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of neighbors perceived to be using
only the RSVP IP Encapsulation."
::= { rsvpIfEntry 2 }
rsvpIfNbrs OBJECT-TYPE
SYNTAX Gauge32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of neighbors currently perceived;
this will exceed rsvpIfIpNbrs + rsvpIfUdpNbrs
by the number of neighbors using both encapsu-
lations."
::= { rsvpIfEntry 3 }⚠️ bestie, the total count (rsvpIfNbrs) is the one that's bigger than the other two added together 🙈 That's because some neighbors use both encapsulations, so they get counted in each bucket and in the total.
Next are the refresh knobs ⏰ rsvpIfRefreshBlockadeMultiple is the "Kb" value and rsvpIfRefreshMultiple is the "K" value, both read-create with defaults you can change 💜
rsvpIfRefreshBlockadeMultiple OBJECT-TYPE
SYNTAX INTEGER (1..65536)
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The value of the RSVP value 'Kb', Which is the
minimum number of refresh intervals that
blockade state will last once entered."
DEFVAL { 4 }
::= { rsvpIfEntry 4 }
rsvpIfRefreshMultiple OBJECT-TYPE
SYNTAX INTEGER (1..65536)
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The value of the RSVP value 'K', which is the
number of refresh intervals which must elapse
(minimum) before a PATH or RESV message which
is not being refreshed will be aged out."
DEFVAL { 3 }
::= { rsvpIfEntry 5 }Now the TTL 🧚 rsvpIfTTL is the SEND_TTL used on this interface for messages the node starts itself, and zero means "no override," so the node figures out TTL some other way 🫶
rsvpIfTTL OBJECT-TYPE
SYNTAX INTEGER (0..255)
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The value of SEND_TTL used on this interface
for messages this node originates. If set to
zero, the node determines the TTL via other
means."
DEFVAL { 0 } -- which is to say, no override
::= { rsvpIfEntry 6 }Timers next ⏱️✨ rsvpIfRefreshInterval is the "R" value, the minimum gap between refresh transmissions of a given PATH or RESV message, and it's in milliseconds with a default of 3000 (that's 30 seconds). rsvpIfRouteDelay is the rough time between a route changing and the matching message showing up on the interface, measured in hundredths of a second with a default of 200 (2 seconds) 🎀
rsvpIfRefreshInterval OBJECT-TYPE
SYNTAX TimeInterval
UNITS "milliseconds"
MAX-ACCESS read-create

DESCRIPTION
"The value of the RSVP value 'R', which is the

DESCRIPTION
"The approximate period from the time a route
is changed to the time a resulting message ap-
pears on the interface."
DEFVAL { 200 } -- 2 seconds
::= { rsvpIfEntry 8 }Now the on/off switches 🔥 rsvpIfEnabled is TRUE when RSVP is turned on for this interface and FALSE when it isn't. rsvpIfUdpRequired is where it gets spicy: when it's TRUE, manual config forces UDP encapsulation, and when it's FALSE, UDP only gets used if there's at least one UDP neighbor 👑
rsvpIfEnabled OBJECT-TYPE
SYNTAX TruthValue
MAX-ACCESS read-create

DESCRIPTION
"If TRUE, manual configuration forces the use

::= { rsvpIfEntry 10 }Last one for the interface table 🌈 rsvpIfStatus is active on any interface that's set up for RSVP, so it's basically the "is this row live?" light 💖
rsvpIfStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"'active' on interfaces that are configured for
RSVP."
::= { rsvpIfEntry 11 }Now we're on to the neighbor table 🍓 The comment says it lists the neighbors the RSVP process is currently getting messages from, and each row is keyed by interface index plus neighbor address 🧚

}Here are the three columns for each neighbor ✨ rsvpNbrAddress is the IPv4 or IPv6 address the neighbor uses, and it can't be changed while the row is active 🙈 rsvpNbrProtocol is the encapsulation that neighbor is using. rsvpNbrStatus is active for all neighbors and can be used to configure them. Oh, and the implementation may (but is not required to) narrow valid neighbors down to the configured ones 💅
rsvpNbrAddress OBJECT-TYPE

ier."
::= { rsvpNotifications 2 }newFlow fires when a system has installed a new flow in its classifier, or (when reservation authorization is in play) is ready to install one and is asking for permission 🙋♀️ Authorization gets given or denied by writing to intSrvFlowStatus. lostFlow is the opposite vibe: a flow got removed from the classifier 😭
Conformance time 🎀 The groups and compliances hang off rsvpConformance, so that's how the spec keeps score on what's required 💜

MODULE -- this module
MANDATORY-GROUPS {
rsvpSessionGroup, rsvpSenderGroup, rsvpResvGroup,
rsvpIfGroup, rsvpNbrGroup
}
GROUP rsvpResvFwdGroup
DESCRIPTION
"The Reservation Requests table is appropriate
in implementations that store upstream reserva-
tion messages, but not appropriate in implemen-
tations which calculate them on each transmis-
sion."

DESCRIPTION
"The notifications in this module may be used to
advise a network management station of changes in
flow status, and are required when this use is in
view."
OBJECT rsvpSessionRequests
MIN-ACCESS not-accessible
DESCRIPTION
"This object is optional."The compliance statement says this module needs the Integrated Services MIB too 🌟 The mandatory groups are the session, sender, reservation, interface, and neighbor groups, and the reservation forwarding group is only a good fit when the implementation stores upstream reservation messages instead of recalculating them each time 💅 The notification group is required when flow-status notifications are in use 🔥
Now the minimum-access list 🧚 Every object here is allowed to be read-only for compliance, so you don't need full read-create access. That's a lot of sender objects, so I'm keeping the vibe consistent and copying each one exactly 💖

END4. Security Considerations ✨
okay bestie, this part is short but it's SERIOUS 😭🔒. Using an SNMP SET to make an RSVP or Integrated Services reservation follows rules that are different from the ones you'd get if the reservation was negotiated using RSVP itself. So be careful with that one 👀. The only other security considerations are the ones that come with SNMP itself, so if you're worried about security, go check out SNMP's own stuff 🫶.
