Configuring IPv4 RIB inter-protocol FRR
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter RIB view.
rib
N/A
3. Create the RIB IPv4 address
family and enter its view.
address-family ipv4
By default, no RIB IPv4
address family exists.
4. Enable IPv4 RIB
inter-protocol FRR.
inter-protocol fast-reroute
[ vpn-instance vpn-instance-name ]
By default, inter-protocol
FRR is disabled.
If you do not specify a VPN
instance, inter-protocol FRR
is enabled for the public
network.
Configuring IPv6 RIB inter-protocol FRR
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter RIB view.
rib
N/A
3. Create the RIB IPv6 address
family and enter its view.
address-family ipv6
By default, no RIB IPv6
address family exists.
4. Enable IPv6 RIB
inter-protocol FRR.
inter-protocol fast-reroute
[ vpn-instance vpn-instance-name ]
By default, inter-protocol
FRR is disabled.
If you do not specify a VPN
instance, inter-protocol FRR
is enabled for the public
network.
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 Command Remarks
1. Enter system view.
system-view N/A
2. Enter RIB view.
rib N/A
3. Create the RIB IPv4 address
family and enter its view.
address-family ipv4
By default, no RIB IPv4 address
family exists.
