Can you help me understand the case? Router A, B ,and C are in the same AS. Topology is A – B – C-loopback(220.127.116.11). and A and C are BGP neighbor. A,B,C are full BGP connection. Publish network 18.104.22.168. Router A can see 22.214.171.124 in routing table only after turning off synchronization. Why ? thank you.
