Static Routing-Track-Bfd Collaboration Configuration Example - HP MSR Series Configuration Manual

Static routing-Track-BFD collaboration configuration example

Network requirements
As shown in
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. Configure the IP address of 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.
