IPv6 BGP Commands

Border Gateway Protocol (BGP) is an external gateway protocol that transmits interdomain routing

information within and between Autonomous Systems (AS). BGP version 4 (BGPv4) supports

classless interdomain routing and the aggregation of routes and AS paths. Basically, two routers (called

neighbors or peers) exchange information including full routing tables and periodically send messages

to update those routing tables.

The following commands allow you to configure and enable BGP.

• aggregate-address

• bgp always-compare-med

• bgp bestpath as-path ignore

• bgp bestpath med confed

• bgp bestpath med missing-as-best

• bgp client-to-client reflection

• bgp cluster-id

• bgp confederation identifier

• bgp confederation peers

• bgp dampening

• bgp default local-preference

• bgp enforce-first-as

• bgp fast-external-fallover

• bgp four-octet-as-support

• bgp graceful-restart

• bgp log-neighbor-changes

• bgp non-deterministic-med

• bgp recursive-bgp-next-hop
