All,
I would appreciate any help on this - been looking at it all day.
I have a remote site LAN 192.168.143.0 /24, with 2 x routers. One of the routers connects to the HQ via the Internet, the other router, on the same LAN, connects to the Head Office via a Concentrator in a Co-Lo. On the Inside of the Concentrator I have a 2800 router that connects to an MPLS network.
(Internet Route) Remote Site----VPN Concentrator---2800 Router-----MPLS----/ (router 1) / / Head Office / / Remote site----------------------MPLS--------------------/ (router 2) (MPLS route)
The Head Office has 2 x routers as well.
I have been trying to figure out how to dynamically learn the route to
192.168.43.X /24 on the Concentrator so that I can push it out to the 2800 and onward advertise it into my Head Office via the MPLS network.Not being a Concentrator guru, I have been through various options (reverse route injection) etc to advertise the remote route to my Head Office but nothing that convinces me that i am doing it correctly.
I need this to be dynamic as I am policy routing. Most of the traffic will go over the VPN. If the VPN fails I need all traffic to re-route via the active MPLS connection.
At present I find that my Head Office site sees the VPN as even after I 'pull' the Internet connection out. This blackholes the traffic instead of detecting the VPN failure and routing it all via the MPLS.
In summary my question is how I detect the remote LAN presence on my Concentrator to advertise it to my 2800. Furthermore, how I successfully detect the VPN failure so I can ensure that any dynamic routing is removed from he Concentrator routing table.
Regards
Darren
