I have run into an issue where I am getting this error:
%MLSCEF-SP-4-FIB_EXCEPTION_THRESHOLD: Hardware CEF entry usage is at 95% capacity for MPLS protocol.
Currently I am set up like this:
FIB TCAM maximum routes :
=======================
Current :-
-------
IPv4 - 900k
MPLS - 20k
IPv6 + IP Multicast - 48k (default)
And I have the current exception status:
#sh mls cef exception status
Current IPv4 FIB exception state = FALSE
Current IPv6 FIB exception state = TRUE
Current MPLS FIB exception state = TRUE
and I have the current summary:
#sh mls cef summary
Total routes: 783690
IPv4 unicast routes: 714439
IPv4 Multicast routes: 4
MPLS routes: 20480
IPv6 unicast routes: 48767
IPv6 multicast routes: 3
EoM routes: 0
I Realize that updating this will require a reboot. I see that cisco says my card RSP720-3CXL-GE has space for 1 million. So looking at this it looks like I will be able to use 32k more routes. so I can add 20 to the MPLS and 12 to the IPv6. Is this correct? Will this require a reboot after each change? Or can I change everything then reboot? Does anyone have any opinions my plan for splitting up the TCAM space?
