Thus it's really hard to even try break an MD5 protected BGP session if you can't even establish the TCP connection. Everything that I've seen or set up had an ACL to only allow the peer(s) to be able to connect to (from memory) TCP port 179. Is there something that I've missed the boat on? #learningOpportunity
To further harden your setup, consider using GTSM https://tools.ietf.org/html/rfc5082 Kind regards, Job
