Configuring a Global Topology and Associating It with an Interface
Follow these steps to enable a global topology in the default VRF and to enable its use with a specific interface.
SUMMARY STEPS

address-family { ipv4 | ipv6 } multicast topology topo-name
3.
maximum prefix limit
4.
interface type interface-path-id
5.
address-family { ipv4 | ipv6 } multicast topology topo-name

DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Configures a topology in the default VRF table that
will be associated with a an interface.
address-family { ipv4 | ipv6 } multicast topology topo-name
Example:
RP/0/RSP0/CPU0:router(config)# address-family ipv4
multicast topology green
Step 2
(Optional) Limits the number of prefixes allowed
in a topology routing table. Range is 32 to 2000000.
maximum prefix limit
Example:
RP/0/RSP0/CPU0:router(config-af)# maximum prefix 100
Step 3
Specifies the interface to be associated with the
previously specified VRF table that will add the
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-af)# interface
GigabitEthernet 0/3/0/0
Step 4
connected and local routes to the appropriate routing
table.
Enables the topology for the interface specified in
Step 4, on page 292, adding the connected and local
routes to the appropriate routing table.
address-family { ipv4 | ipv6 } multicast topology topo-name
Example:
RP/0/RSP0/CPU0:router(config-if)# address-family ipv4
multicast topology green
Step 5
—
Repeat Step 4 and Step 5 until you have specified all the interface
instances you want to associate with your topologies.
Step 6
Example:
RP/0/RSP0/CPU0:router(config-if-af)# interface
