Configuring IPv4 RIB inter-protocol FRR

Step
1. Enter system view.
2. Enter RIB view.
3. Create the RIB IPv4 address
family and enter its view.
4. Enable IPv4 RIB
inter-protocol FRR.

Configuring IPv6 RIB inter-protocol FRR

Step
1. Enter system view.
2. Enter RIB view.
3. Create the RIB IPv6 address
family and enter its view.
4. Enable IPv6 RIB
inter-protocol FRR.

Configuring routing policy-based recursive lookup

When a route changes, the routing protocol has to perform a route recursion if the next hop is
indirectly connected. The routing protocol might select an incorrect path, which can cause traffic loss.
To prevent this problem, you can use a routing policy to verify the recursive route. If the recursive
route fails to match the routing policy, the routing protocol invalidates the route and marks it as
unreachable.
For the device to use exact routes to forward the traffic, make sure all desired routes can match the
routing policy.
To configure routing policy-based recursive lookup:
Step
1. Enter system view.
2. Enter RIB view.
3. Create the RIB IPv4 address
family and enter its view.
