The source and destination IP addresses or peering interfaces should to
be a mirror image of each other.

Subject: tunnel interface - does src/dst ip matter?
Hi, group
From what I understand, the source and destination IPs of a GRE tunnel
interfaces can be any IPs on the 2 routers as long as they are
reachable, but one of the labs I am working proved I was wrong, can
anyone give some insight?
TIA,
Pat
