Configuring An Ipv6 Bgp Route Reflector; Configuring Bfd For Ipv6 Bgp - HP 3600 v2 series Configuration Manual

Configuring an IPv6 BGP route reflector

Follow these steps to configure an IPv6 BGP route reflector:
To do...
Enter system view
Enter BGP view
Enter IPv6 address family view
Configure the router as a route
reflector and specify an IPv6 peer
or peer group as a client
Enable route reflection between
clients
Configure the cluster ID of the
route reflector
NOTE:
Because the route reflector forwards routing information between clients, you must make clients of a
•
route reflector fully meshed. If clients are fully meshed, HP recommends disabling route reflection
between clients to reduce routing costs.
If a cluster has multiple route reflectors, you must specify the same cluster ID for these route reflectors to
•
avoid routing loops.

Configuring BFD for IPv6 BGP

IPv6 BGP maintains neighbor relationships based on the keepalive timer and holdtime timer, which are
set in seconds. IPv6 BGP defines that the holdtime interval must be at least three times the keepalive
interval. This mechanism makes the detection of a link failure rather slow and thus causes a large quantity
of packets to be dropped especially when the failed link is a high-speed link. You can enable BFD to
detect the link to a peer. BFD can quickly detect any link failure and thus reduce network convergence
time.
Follow these steps to enable BFD for a BGP peer:
To do...
Enter system view
Enable BGP and enter BGP view
Enter IPv6 address family view
Enable BFD for the specified BGP
peer
Use the command...
system-view
bgp as-number
ipv6-family
peer { ipv6-group-name |
ipv6-address } reflect-client
reflect between-clients
reflector cluster-id cluster-id
Use the command...
system-view
bgp as-number
ipv6-family
peer ipv6-address bfd
