Bfd For Static Routes Configuration Example (Indirect Next Hop) - HP FlexFabric 12900E Series Configuration Manual

Static Routing table Status : <Inactive>
Summary Count : 0
The output shows that Switch A communicates with Switch B through VLAN-interface 11.

Network requirements
Figure 4 shows the network topology as follows:
•
Switch A has a route to interface Loopback 1 (2.2.2.9/32) on Switch B, with the output interface
VLAN-interface 10.
•
Switch B has a route to interface Loopback 1 (1.1.1.9/32) on Switch A, with the output interface
VLAN-interface 12.
•
Switch D has a route to 1.1.1.9/32, with the output interface VLAN-interface 10, and a route to
2.2.2.9/32, with the output interface VLAN-interface 12.
Configure the following:
•
Configure a static route to subnet 120.1.1.0/24 on Switch A.
•
Configure a static route to subnet 121.1.1.0/24 on Switch B.
•
Enable BFD for both routes.
•
Configure a static route to subnet 120.1.1.0/24 and a static route to subnet 121.1.1.0/24 on both
Switch C and Switch D.
When the link between Switch A and Switch B through Switch D fails, BFD can detect the failure
immediately. Switch A then communicates with Switch B through Switch C.
