# 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
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.

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.
<SwitchA> system-view
[SwitchA] bgp 200
[SwitchA-bgp] router-id 1.1.1.1
[SwitchA-bgp] peer 3001::3 as-number 200
: 0
Figure 77, configure OSPFv3 as the IGP in AS 200.
