First sorry fo my bad english.
I need help for this: i have 3 sites with 3 cisco connected in vpn ipsec and GRE.
I have to add another router in this configuration, i copy the previous commande line to configure it from a working running config but the vpn dont get up between my new router and the others ...
i join 3 config files: RT-marseille (i have modify it to accept the new router), RT-paris (the new router with the command line i have copied) and RT-cogolin (a router that work without pb with RT-marseille and that i have to modify after to accept RT-paris). i also join a partial copy of the debug crypto isakmp on both RT-paris and RT-marseille.
Thanx for help, i very dont know what to do !!!
