Looks like you're using a RSP720-3C, which has that TCAM limitation. You need RSP720-3CXL do take more routes.

Hi,

Got the issue, but what would be the work around for this?  Mqaximum i am
allowed is 223K.


12:44:10.257: %MLSCEF-SP-4-FIB_EXCEPTION_THRESHOLD: Hardware CEF entry usage
is at 95% capacity for MPLS protocol.
12:44:09.650: %MLSCEF-SP-STDBY-4-FIB_EXCEPTION_THRESHOLD: Hardware CEF entry
usage is at 95% capacity for MPLS protocol.
12:44:13.182: %CFIB-SP-STDBY-3-CFIB_EXCEPTION: FIB TCAM exception for IPv4
unicast. Packets through some routes will be dropped.
Use "mls cef maximum-routes" to modify the FIB TCAM partition or/and
consider a hardware upgred.
Examine your network and collect the necessary information from this setup.
The only way to recover from this state is by reload the  router.
