Refer to the exhibit. An engineer working for a private telecommunication company with an employee id: 1234:56:789 notices that the customer network going through AS30-AS65001-AS65000 is experiencing packet drops when it accesses an application at 172.16.20.1/32 in the DC cloud. The BGP link between AS20 and AS30 is inaccessible because of a fiber cut. Routers RL, RN, and RZ are configured with confederation identifier 10. Which action resolves this issue?
The issue relates to BGP notification messages indicating that the peer is in the wrong AS. This suggests a configuration problem with BGP confederation peers. Router RX needs to be configured correctly with the BGP confederation peers ASN for proper communication. The optimal solution is to configure RX with its confederation peers correctly, which is done by specifying 'bgp confederation peers 65000'. This ensures that RX recognizes its peers within the confederation correctly, resolving the issue as described in option A.
You get those errors if you don't configure the bgp confederation peers ASN on RX Correct is A
But wouldn't joining RX in the confederation identifier 10 accomplish the same thing?
