Display BFD IPv6 Neighbor Information

BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see Fabric Engine and VOSS Feature Support Matrix.

About this task

Use this procedure to display information about BFD IPv6 neighbors.

Procedure

  1. To enter User EXEC mode, log on to the switch.
  2. Display BFD neighbor information:

    show ipv6 bfd neighbors

  3. Optional: Display BFD neighbor next-hop information:

    show ipv6 bfd neighbors next-hop WORD<0-128>

  4. Optional: Display BFD neighbor information for a particular VRF:

    show ipv6 bfd neighbors vrf WORD<1-16>

  5. Optional: Display BFD neighbor information for a range of VRFs:

    show ipv6 bfd neighbors vrfids WORD<0-512>

Example

The following example displays BFD session information for an IPv6 neighbor.

Switch:1>show ipv6 bfd neighbors

Variable Definitions

The following table defines parameters for the show ipv6 bfd neighbors command.

Variable

Value

WORD<0-128>

Specifies the next-hop IPv6 address in the format a:b:c:d:e:f:g:h.

vrf WORD<1-16>

Specifies a VRF instance by name (the string length ranges from 1–16 characters).

vrfids WORD<0-512>

Specifies a range of VRFs by ID number (the ID ranges from 0–512).
