CISCO_BGP4_MIB

Revision: 2010-09-30

An extension to the IETF BGP4 MIB module defined in RFC 1657.

Following is the terminology associated with Border Gateway Protocol(BGP).

UPDATE message
UPDATE messages are used to transfer routing information between BGP peers. An UPDATE message is used to advertise a single feasible route to a peer, or to withdraw multiple unfeasible routes from service.
Adj-RIBs-In
The Adj-RIBs-In store routing information that has been learned from inbound UPDATE messages. Their contents represent routes that are available as an input to the Decision Process.
Loc-RIB(BGP table)
The Loc-RIB contains the local routing information that the BGP speaker has selected by applying its local policies to the routing information contained in its Adj-RIBs-In.
Adj-RIBs-Out
The Adj-RIBs-Out store the information that the local BGP speaker has selected for advertisement to its peers. The routing information stored in the Adj-RIBs-Out will be carried in the local BGP speaker’s UPDATE messages and advertised to its peers.
Path Attributes
A variable length sequence of path attributes is present in every UPDATE. Each path attribute is a triple <attribute type, attribute length, attribute value> of variable length.
Network Layer Reachability Information(NLRI)
A variable length field present in UPDATE messages which contains a list of Network Layer address prefixes.
Address Family Identifier(AFI)
Primary identifier to indicate the type of the Network Layer Reachability Information(NLRI) being carried.
Subsequent Address Family Identifier(SAFI)
Secondary identifier to indicate the type of the Network Layer Reachability Information(NLRI) being carried.
