1. Introduction This document provides a survey of BGP-4 v1 MIB [
RFC4274 ]
implementations. After a brief summary, each response is listed.
The authors make no claim as to the accuracy of the information
provided.
The following organizations reported having BGP-4 MIB
implementations: Cisco Systems, Redback Networks, and NextHop
Technologies.
2. Survey Summary This survey asked for information about the implementations of the
BGP-4 [
RFC4271 ] that support MIB agents [
RFC1657 ] according to the
BGP-4 v1 MIB [
RFC4274 ].
Two or more of the implementations of BGP-4 v1 MIB [
RFC4274 ] each
implement all the objects. None of the implementations that
responded to the survey implemented the read-write variables (
Section 2.2 ). The two TRAPs as specified are not implemented by two
implementations (
Section 2.3 ). The counters' initialized state is
zeroed in all implementations, but a reset peer is only reset by the
Redback implementation (
Section 2.4 ).
There are 3 agent implementations for the 3 surveyed (
Section 2.5 ).
The Simple Network Management Protocol (SNMP) managers used to test
the implementations are: Net-SNMP (www.net-snmp.org), Multi Router
Traffic Grapher (www.mrtg.org), and the internal Cisco manager.
No interoperability issues related to the Manager specification were
found.
2.1. MIB Agent Object Implementation Summary Cisco NextHop Redback

Y Y Y bgpPeerLocalAddr
Y Y Y bgpPeerLocalPort
Y Y Y bgpPeerRemoteAddr
Y Y Y bgpPeerRemotePort
Y Y Y bgpPeerRemoteAs
Y Y Y bgpPeerInUpdates
2.2. MIB Agent Read-Write Object Implementation Summary Does your implementation allow managers to write to the following
read-write objects? Indicate yes or no (Y or N) for each object:
Cisco NextHop Redback
N N N bgpPeerAdminStatus
N N N bgpPeerConnectRetryInterval
N N N bgpPeerHoldTimeConfigured
N N N bgpPeerKeepAliveConfigured
N N N bgpPeerMinASOriginationInterval
N N N bgpPeerMinRouteAdvertisementInterval
None of the implementations surveyed supported the read/write
variables.
2.3. MIB Agent Trap Implementation Summary Does your implementation include each of the following notifications?
Indicate yes or no (Y or N) for each notification:
Cisco NextHop Redback
Y N N bgpEstablished
Y N Y*1 bgpBackwardTransition
*1 - Redback only supports the transition from Established to
Idle.
2.4. MIB Agent BGP Peer Reset state Two questions were asked about the bgpPeerInUpdates,
bgpPeerOutUpdates, bgpPeerInTotalMessages and
bgpPeerOutTotalMessages.
The first was "Do you initialize these counters to zero?", and the
second was "Do you reset these counters to zero when a configured
peer enter the established state?"
Cisco NextHop Redback
Y Y Y initialize to zero
N N Y reset to zero when configured peer
Enters established state
2.5. MIB Manager Interactions Managers:
BGP MIB agent:
Cisco NextHop Redback
Y Y N independent implementation
- - C (P or C)public or commercial
Redback code based on SNMP Research EMANATE
SNMP Manager Interaction
Cisco NextHop Redback
cisco Net-SNMP MRTG SNMP Managers tested with
- Y Y Manager implemented independently
from agent
- Y Y Read access to BGP-4 MIB
variables.
N N N Write access to BGP-4 MIB
variables.
- N Y Sending and receiving BGP-4 MIB
notifications.
Y Y Y Tested using SNMPv1/v2c.
Y N Y Tested using SNMPv3.
"-" indicates cisco did not answer these questions.
NextHop SNMP agent support is via SNMP Multiplex (SMUX)
interface.
MRTG SNMP is found at www.mrtg.org. Net-SNMP (UC Davis tools)
