Vishal,

I have not yet had the chance to try to replicate this bug in my
environment.  Will you file this  as a bug?  Gateway IPs on external
networks don't change much.  In most environments there is never a
need to change the IP.  However, if the API does not have a constraint
to prevent the change then the L3 agent should affect it properly.  We
can discuss more in the bug report.

Could you reply with the bug number?  The L3 subteam will triage.
