Configuring Bfd For Ipv6 Bgp - HP MSR Series Configuration Manual

IPsec policy name: policy002, SPI :54321
Routing policy configured:
No routing policy is configured
The output shows that both IBGP and EBGP neighbor relationships have been established, and all
protocol packets are protected by IPsec.

Configuring BFD for IPv6 BGP

Network requirements
As shown in
Establish two IBGP connections between Router A and Router C. When both links are working, Router C
adopts the link Router A<—>Router B<—>Router C to exchange packets with network 1200::0/64.
Configure BFD over the link. Then if the link fails, BFD can quickly detect the failure and notify it to IPv6
BGP. Then the link Router A<—>Router D<—>Router C takes effect immediately.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPFv3 to make sure that Router A and Router C are reachable to each other. (Details
not shown.)
3. Configure IPv6 BGP on Router A:
# Establish two IBGP connections between Router A and Router C.
<RouterA> system-view
[RouterA] bgp 200
[RouterA-bgp] ipv6-family
[RouterA-bgp-af-ipv6] peer 3002::2 as-number 200
[RouterA-bgp-af-ipv6] peer 2002::2 as-number 200
[RouterA-bgp-af-ipv6] quit
# When the two links between Router A and Router C are both up, Router C adopts the link Router
A<—>Router B<—>Router C to exchange packets with network 1200::0/64. (Set a higher MED
value for route 1200::0/64 sent to peer 2002::2 on Router A.)
Create IPv6 ACL 2000 to permit 1200::0/64 to pass.
[RouterA] acl ipv6 number 2000
Figure 102, configure OSPFv3 as the IGP in AS 200.
