What are the two solutions to fix the issue?

Refer to the exhibit.

BGP is flapping after the Copp policy is applied.

What are the two solutions to fix the issue? (Choose two)
A . Configure BGP in the COPP-CRITICAL-7600 ACL
B . Configure a higher value for CIR under the default class to allow more packets during peak traffic
C . Configure a higher value for CIR under the class COPP-CRITICAL-7600
D . Configure a three-color policer instead of two-color policer under class COPP-CRITICAL-7600
E . Configure IP CEF to CoPP policy and BGP to work

Answer: AB

Explanation:

The policy-map COPP-7600 only rate-limit HTTP & HTTPS traffic (based on the ACL conditions) so any BGP packets will be processed in the class “class-default”, which drops exceeded BGP packets. Therefore we have two ways to solve this 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)
