Static Routing-Track-Bfd Collaboration Configuration Example - HPE FlexNetwork HSR6800 series Configuration Manual

Static routing-Track-BFD collaboration configuration
example
Network requirements
As shown in
20.1.1.0/24 and 30.1.1.0/24. Configure static routes on these routers so that the two segments can
communicate with each other. Configure route backup to improve network reliability.
Router A is the default gateway of the hosts in segment 20.1.1.0/24. Two static routes to 30.1.1.0/24
exist on Router A, with the next hop being Router B and Router C, respectively. These two static
routes back up each other, where:
•
The static route with Router B as the next hop has a higher priority, and is the master route. If
this route is available, Router A forwards packets to 30.1.1.0/24 through Router B.
•
The static route with Router C as the next hop acts as the backup route.
•
Configure static routing-track-BFD collaboration to determine whether the master route is
available in real time. If the master route is unavailable, BFD can quickly detect the route failure
to make the backup route take effect. Router A forwards packets to 30.1.1.0/24 through Router
C and Router B.
Similarly, Router B is the default gateway of the hosts in segment 30.1.1.0/24. Two static routes to
20.1.1.0/24 exist on Router B, with the next hop being Router A and Router C, respectively. These
two static routes back up each other, where:
•
The static route with Router A as the next hop has a higher priority, and is the master route. If
this route is available, Router B forwards packets to 20.1.1.0/24 through Router A.
•
The static route with Router C as the next hop acts as the backup route.
•
Configure static routing-track-BFD collaboration to determine whether the master route is
available in real time. If the master route is unavailable, BFD can quickly detect the route failure
to make the backup route take effect. Router B forwards packets to 20.1.1.0/24 through Router
C and Router A.

Configuration procedure
1. Specify the IP address for each interface as shown in
2. Configure Router A:
# Configure a static route to 30.1.1.0/24, with the address of the next hop as 10.2.1.2 and the
default priority 60. This static route is associated with track entry 1.
<RouterA> system-view
[RouterA] ip route-static 30.1.1.0 24 10.2.1.2 track 1
# Configure a static route to 30.1.1.0/24, with the address of the next hop as 10.3.1.3 and the
priority 80.
