437
ipv6-address: IPv6 address of a peer.
as-path-acl-number: Number of an AS path ACL, in the range of 1 to 256.
import: Filters incoming routes.
export: Filters outgoing routes.
Examples
# Specify the AS path ACL 3 to filter routes outgoing to the peer 1:2::3:4.
<Sysname> system-view
[Sysname] ip as-path 3 permit ^200
[Sysname] bgp 100
[Sysname-bgp] ipv6-family
[Sysname-bgp-af-ipv6] peer 1:2::3:4 as-path-acl 3 export
peer bfd (IPv6 address family view/IPv6 BGP-VPN instance
view)
Use peer bfd to enable BFD over the link to a BGP peer.
Use undo peer bfd to restore the default.
Syntax
peer ipv6-address bfd
undo peer ipv6-address bfd
Default
BFD is not enabled for any BGP peer.
Views
IPv6 address family view, IPv6 BGP-VPN instance view
Default command level
2: System level
Parameters
ipv6-address: IPv6 address of a peer.
Usage guidelines
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
[Sysname-bgp-af-ipv6] peer 100::1 bfd
