Viewing BGPv6 neighbors information

View information about BGPv6 neighbors.

Procedure

  1. To enter User EXEC mode, log on to the switch.
  2. View information about BGPv6 neighbors:

    show bgp ipv6 neighbors [WORD<1–256>] [vrf <WORD 1-16>] [vrfids <0-255>]

  3. View information about BGPv6 peer advertised routes:

    show bgp ipv6 neighbors WORD<1–256> advertised-routes [WORD<1–256>] [longer-prefixes] [vrf <WORD 1-16>] [vrfids <0-255>]

  4. View information about BGPv6 peer routes:

    show bgp ipv6 neighbors WORD<1–256> routes [WORD<1–256>] [community <enable|disable>] [vrf <WORD 1-16>] [vrfids <0-255>]
