Hardware CEF entry usage is at 95% capacity for MPLS protocol.

[Dani Simanjuntak]

Hello,

I have router that use WS-SUP32-GE-3B, 

I have error after upgrade my IOS : 

%MLSCEF-SP-4-FIB_EXCEPTION_THRESHOLD: Hardware CEF entry usage is at
95% capacity for IPv4 unicast protocol

#sh mls cef summary

Total routes:                     216546
    IPv4 unicast routes:          194260
    IPv4 Multicast routes:        3
    MPLS routes:                  2048
    IPv6 unicast routes:          20235
    IPv6 multicast routes:        3
    EoM routes:                   0

Can I adding memory  to solve this problem? Or I must change my supervisor Engine? 

because if I  increase in the size of the IPv4 TCAM space always reduces the amount of TCAM space that is available to IPv6

Thanks.
