Hello all,
I am with problem that sometimes the comunication is lost, the lik was working propelly but suddenly the comunication get down. When I access the router by console and I remove the virtual-template and change the ppp protocol for IETF, and the other end change for aal5nldpid, the link become UP.
I have the follow topology:
frame-relay ---> telco ---> ATM
end satation end station
CONFIG FRAME-RELAY
interface Serial0/0.1 point-to-point
description INTERFACE FRAME-RELAY END STATION
bandwidth 128
ip address
ip nbar protocol-discovery
ip ospf cost 170

Which IOS are you using, and does it work if you reload the router with the PPP configuration ?

IOS is C3745-JSX-M.12.3.19.
Same doing reload the comunication is not working.
I did test now and note that if I creat the new virtual-template and sub-interface, the link back working.
I think that problem could be in virtual-access....

You can be running into a bug, can you upgrade to latest image of 12.3 or 12.4 and try again ?

A bug that causes the symptoms you are seeing - at reboot with correct config doesn't work, then you configure it again and it starts working.
