Re: conditional routing

Thanks Carlos for the reply.

Actually I have a service running on two sites (Main and DR), Requirement
is to keep the same IP for service. when the service is running from main
site, the IP should be advertised from main site, while when the service is
down at main site and it becomes available through DR site, the same IP
should be advertised through DR..
