To specify the maximum number of routes that can be programmed in the FIB TCAM for a protocol,
perform these tasks in privileged mode:
This example shows how to specify the maximum number of routes for IP unicast:
Console> (enable) set mls cef maximum-routes ip 220
Configuration change will take effect after next reboot.
Console> (enable) show mls cef maximum-routes
Current:
IPv4 :192k (default)
IPv4 multicast : 32k (default)
User configured:(effective after reboot)
IPv4 :220k
IPv4 multicast : 16k (adjusted default)
Console> (enable)

You must enable IP multicast routing globally on MSFC2/MSFC3 before you can enable PIM on
MSFC2/MSFC3 interfaces.
Task Command

that can be programmed in the FIB
TCAM for a protocol.
