Configuring MBGP Route Redistribution
MBGP can advertise routing information in the local AS to neighboring ASs. It redistributes such
routing information from IGP into its routing table rather than learns the information by itself.
Follow these steps to configure MBGP route redistribution:
To do… Use the command… Remarks
Enter system view system-view —
Enter BGP view bgp as-number —
Enter IPv4 MBGP address family
view
ipv4-family multicast —
Enable route redistribution from
another routing protocol
import-route protocol
[ { process-id | all-processes }
[ med med-value | route-policy
route-policy-name ] * ]
Inject a network into the MBGP
routing table
network ip-address [ mask |
mask-length ] [ short-cut |
route-policy route-policy-name ]
At least one of these approaches
is required.
No route redistribution is
configured by default.
z The Origin attribute of routes redistributed into the MBGP routing table with the import-route
command is Incomplete.
z The Origin attribute of routes injected into the MBGP routing table with the network command is
IGP.
z The networks to be injected must exist in the local IP routing table, and using a route policy
makes route control more flexible.
Configure Default Route Redistribution into MBGP
Using the import-route command cannot redistribute any default route into MBGP. This task allows
you to do so.
Follow these steps to configure MBGP to redistribute a default route from another protocol:
To do… Use the command… Remarks
Enter system view system-view —
Enter BGP view bgp as-number —
Enter MBGP address family view ipv4-family multicast —
