[RouterC-bgp-ipv4] peer 9.1.1.1 enable
Verifying the configuration
Ping Router C on Router A. Meanwhile, perform an active/standby switchover on Router B. The ping
operation is successful during the whole switchover process.
BFD for BGP configuration example
Network requirements
As shown in Figure 71,
• Run OSPF in AS 200.
• Establish two IBGP connections between Router A and Router C. When both paths are working,
Router C adopts the path Router A<—>Router B<—>Router C to communicate with network
1.1.1.0/24. Configure BFD over the path. If the path fails, BFD can quickly detect the failure and
notify it to BGP. Then the path Router A<—>Router D<—>Router C takes effect immediately.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPF so that Router A and Router C can reach each other. (Details not shown.)
3. Configure BGP on Router A:
# Establish two IBGP connections to Router C.
<RouterA> system-view
[RouterA] bgp 200
[RouterA-bgp] peer 3.0.2.2 as-number 200

[RouterA-bgp-ipv4] peer 3.0.2.2 enable
[RouterA-bgp-ipv4] peer 2.0.2.2 enable
[RouterA-bgp-ipv4] quit
# Create ACL 2000 to permit 1.1.1.0/24 to pass.
