how to fix BGP down, I can ping azure IP from my on Prem router. icmp is fine but tcp ping to port 179 is not fine, its dropped. I did some packet capture on router, I cannot see SYN-ACK received from Azure express route. so if tcp handshake is not complete then BGP will remain down. There is no firewall between on-prem router to azure.

Please help how to fix it.
