HP 6125XLG - BFD for Ipv6 BGP Configuration Example

# Ping the IPv6 address 4::4 (loopback interface address) of CE 2 from CE 1. The ping operation
succeeds.
BFD for IPv6 BGP configuration example
Network requirements
As shown in Figure 77, configure OSPFv3 as the IGP in AS 200.
Establish two IBGP connections between Switch A and Switch C. When both paths are working, Switch
C adopts the path Switch A<—>Switch B<—>Switch C to exchange packets with network 1200::0/64.
Configure BFD over the path. Then if the path fails, BFD can quickly detect the failure and notify it to IPv6
BGP. Then the path Switch A<—>Switch D<—>Switch C takes effect immediately.

Switch A Vlan-int100 3000::1/64 Switch C Vlan-int101 3001::3/64
Vlan-int200 2000::1/64 Vlan-int201 2001::3/64

Configuration procedure
1. Configure IPv6 addresses for interfaces. (Details not shown.)
2. Configure OSPFv3 so that Switch A and Switch C can reach each other. (Details not shown.)
3. Configure IPv6 BGP on Switch A:
# Establish two IBGP connections to Switch C.
