We are currently using Nortel Contivity VPN devices between London and International Offices.
Unfortunately the Service Provider has let us countless times and we are now putting in a leased line between one of the branch offices and London.
The attached diagram show the setup we will have. There is no dynamic routing protocol runing in the international branch offices.
The london Office has OSPF running on the LAN between its London sites.
The VPN devices are running a meshed configuration using RIP and a secure tunnels between each of the offices.
All the internet traffic from International offices comes into London.
Obviously implementing the leased line would mean that any traffic destined for other international offices would have to go via london.
1. We are running OSPF on the London LAN what issues will we have if we run ospf on the cisco router in the branch office or is it best to make is point to point link and redistribute statis into OSPF once in london.
2. The question is which link do we make primary , the leased or the Nortel VPN connection. Not sure how to measure the traffic going from the branch to other internal offices.
3. Can HSRP be implemented. Not sure if the Nortel's do HSRP.
3. Does any one have a sample configuration for the 2600 in this scenario ?
