Configuring an IPv6 BGP route reflector
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Enter IPv6 address family
view.
ipv6-family N/A
4. Configure the router as a route
reflector and specify an IPv6
peer/peer group as a client.
peer { ipv6-group-name |
ipv6-address } reflect-client
Not configured by default.
5. Enable route reflection
between clients.
reflect between-clients Enabled by default.
6. Configure the cluster ID of the
route reflector.
reflector cluster-id cluster-id
By default, a route reflector uses its
router ID as the cluster ID.
NOTE:
•
In general, since the route reflector forwards routing information between clients, you are not required
to make clients of a route reflector fully meshed. If clients are fully meshed, H3C recommends disabling
route reflection between clients to reduce routing costs.
• If a cluster has multiple route reflectors, you need to 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.
For more information about BFD, see High Availability Configuration Guide.
IMPORTANT:
Before configuring BFD for IPv6 BGP, you must enable BGP.
