peer bfd (IPv6 address family view/IPv6 BGP-VPN instance
view)
Syntax
peer ipv6-address bfd
undo peer ipv6-address bfd
View
IPv6 address family view, IPv6 BGP-VPN instance view
Default level
2: System level
Parameters
ipv6-address
: IPv6 address of a peer.
Description
Use
peer bfd
to enable BFD over the link to a BGP peer.
Use
undo peer bfd
to restore the default.
By default, BFD is not enabled for any BGP peer.
After a link failure occurs, BFD may detect the failure before the system performs GR, and as a result,
GR will fail. Therefore, if GR capability is enabled for IPv6 BGP, use BFD with caution.
Examples
# Enable BFD over the link to BGP peer 100::1.
<Sysname> system-view
[Sysname] bgp 100
[Sysname] ipv6-family
