I am trying to replace a 3com office connect(which is working fine) with a cisco 1720 and cannot get the replacement to talk to the core routers. The router has three connections, ethernet to local LAN which works fine. The other connections are two frame relay pvc's to different 3com NB11 routers, one is the backup to the other. It is these that have the problem.
They are both in seperate sub-nets. I have double checked that the pvc's ends are not swapped and I have aligned the ip subnets correctly with the pvc's.
I cannot ping the other end of the connection even though the router reports the link up and SH INT shows the interfaces to be up. I did check I'd enabled ip routing.
Help!!
config is below
sh run

When I run various forms of DEBUG IP .... I see that packets from the core router interfaces are not only being sent and recieved but I am also seeing packets (icmp) from my network manager. The ospf side of things is obviously not happening as basic ip connectivity has not be achieved.
