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.
Enabling support for IPv6 routes with prefixes
longer than 64 bits
This feature takes effect at next reboot. Make sure the reboot does not impact your network.
To enable support for IPv6 routes with prefixes longer than 64 bits:
1. Enter system view.
system-view
N/A
2. Enable support for IPv6
routes with prefixes longer
than 64 bits.
switch-routing-mode ipv6-128
By default, the device does not
support IPv6 routes with prefixes
longer than 64 bits.
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:
1. Enter system view.
N/A
2. Enter RIB view.

3. Create the RIB IPv4 address
family and enter its view.
address-family ipv4
By default, no RIB IPv4 address
family exists.
4. Configure routing
policy-based recursive
lookup.

By default, routing policy-based
recursive lookup is not
configured.
