Bfd For Bgp Configuration Example - HPE 5800 Series Configuration Manual

Ping Switch C on Switch A. Meanwhile, perform a master/slave switchover on Switch B. The
ping operation is successful during the whole switchover process.

BFD for BGP configuration example

Network requirements
As shown in
•
Configure OSPF as the IGP in AS 200.
•
Establish two IBGP connections between Switch A and Switch C. When both links are working,
Switch C adopts the link Switch A<—>Switch B<—>Switch C to exchange packets with network
1.1.1.0/24. Configure BFD over the link. Then if the link fails, BFD can quickly detect the failure
and notify it to BGP. Then the link Switch A<—>Switch D<—>Switch C takes effect immediately.

Configuration procedure
Configure IP addresses for interfaces. (Details not shown.)
1.
Configure OSPF in AS 200 to make sure Switch A and Switch C can reach each other, and
2.
configure Switch A to redistribute BGP routes. (Details not shown.)
Configure BGP on Switch A:
3.
# Establish two IBGP connections between Switch A and Switch C, and configure Switch A to
advertise itself as the next hop.
