Explanation:
The policy-map COPP-7600 only rate-limit HTTP & HTTPS traffic (based on the ACLconditions) so any BGP packets will be processed in the class “class-default”, which dropsexceeded BGP packets. Therefore we have two ways to solvethis problem:
+ Add BGP to the ACL with the statement “permit tcp any any eq bgp”
+ Configure higher value for CIR in default class as 2Mbps is too low for web traffic (http &
https)
C takes care when the BGP session is initiated from the peer router
B takes care when the BGP session is initialized from the local router. In this case, the traffic coming in would have destination port of a random number. It would match the default class.
Not Necessary.
COPP-CRITICAL-7600 is configured as;
confirm - transmit
exceed - transmit
Meaning traffic is never dropped, regardless of how high, or low, the CIR is configured as.
Question is asking for 2 different solutions, NOT 2 elements of the same solution.
If the engineer does not want to add BGP to COPP-CRITICAL-7600, another solution is to increase the CIR of class-default, so as to reduce the chances that traffic is dropped, including BGP.
Why change the default settings if bgp falls into COPP-CRITICAL-7600?
For bgp and http(s) you need to make different policies. But I don't see such an option.
