Bfd For Static Routes Configuration Example (Indirect Next Hop) - HP MSR2000 series Configuration Manual

# Display the BFD session information on Switch A.
<SwitchA> display bfd session
Total Session Num: 1
Session Working Under Ctrl Mode:

4/7
The output shows that the BFD session has been created.
# Display static routes on Switch A.
<SwitchA> display ip routing-table protocol static
Public Routing Table : Static
Summary Count : 2
Static Routing table Status : <Active>
Summary Count : 1
Destination/Mask
120.1.1.0/24
Direct Routing table Status : <Inactive>
Summary Count : 1
Destination/Mask
120.1.1.0/24
The output shows that Switch A communicates with Switch B through VLAN-interface 10.
When the link over VLAN-interface 10 fails, Switch A can quickly detect the failure.
# Display static routes information on Switch A again.
<SwitchA> display ip routing-table protocol static
Public Routing Table : Static
Summary Count : 1
Static Routing table Status : <Active>
Summary Count : 1
Destination/Mask
120.1.1.0/24
Static Routing table Status : <Inactive>
Summary Count : 0
The output shows that Switch A communicates with Switch B through VLAN-interface 11 now.

BFD for static routes configuration example (indirect next hop)

Network requirements
As shown in
interface VLAN-interface 10. Switch B has a route to interface Loopback 1 (1.1.1.9/32) on Switch A, with
output interface VLAN-interface 12. Switch D has a route to 1.1.1.9/32, with output interface
VLAN-interface 10, and a route to 2.2.2.9/32, with output interface VLAN-interface 12.
Configure static routes to subnet 120.1.1.0/24 on Switch A, static routes to subnet 121.1.1.0/24 on Switch
B, and static routes to subnets 120.1.1.0/24 and 121.1.1.0/24 on both Switch C and Switch D. Enable BFD
