Hello Experts,

DR Topology

CE----PE(DIST)------PE(CORE)------ISP(PE)----(ISP MPLS CLOUD with PE's
where all other customers are connected)

Sorry Ruhann to reply late,i was stuck is something else.

The HQ and the DR are connected to different PE. There are not any backdoor
link between the DR and the HQ.
The DR is a carrier supporting carrier ,and each customer in DR is connected
via a back to back VRF with the ISP PE router.

Hello Pradeep,

As per ur previous mail u told me that it can be done through AS-path, why
we need this??? As per my knowledge each branch routers have the routes to
HQ and DR, when the HQ fails totally the routes of HQ will disappear from
the routing table of the CE router's and hence users have to open a new
session with the new IP of web application that is located in DR, but what i
want is a seemless failover without chaging the IP address of the web
application

I have read about content switching switches but i m still in doubt, and
also i don't have content switches in my enterprise.

Thanks
