BRI to PRI

I have a 3620 with BRI connecting to a 3640 with a PRI to backup a leased line, using dialer interface on the PRI end. When the fibre goes down, the BRI dials the PRI. Connects OK, with 2 active channels, but cdp doesn't see the router at the other end. (I haven't done anything to manually disable cdp over ISDN). I also can't route anything over it.... ideas?

Re: BRI to PRI

Hi,

Yes I've had this problem before. Try using the legacy dialer - works first time every time!
