Dear All
From cisco document 6500-sup720 and 7600-rsp720 are support IPv4 unicast and MPLS—512,000 routes by default. On my network we have route more than 400K which nearly reach to the limit then I tried to change from 512K to 1007K as below.
Router#sh mls cef maximum-routes
FIB TCAM maximum routes :
=======================
Current :-
-------
IPv4 - 1007k
MPLS - 1k
IPv6 + IP Multicast - 8k (default)
After rebooted I got high cpu issue on both 6500-sup720 and 7600-rsp720 then I tried to tuning to other value such as 600K , 700K and so on but doesn't help.
Summary
- I have no cpu issue with default value for mls cef maximum-route
- I have cpu issue when tuning to other value such as 600K , 700K
Please advise.
Pichet
