asked on

point to point interface problems

Both sites have Cisco 1721 with T1 CSU/DSU.  

Description:

ISSDepot is main site, has internet connection and VPN to other company sites
POATrailer is a trailer located at a project site, only point to point t1 connection back to depot

Cannot get Serial 0 on either router to come up, when I manage to get the interface up the line protocal is down.
Cannot ge the subs (serial0.1) up at all....

any help is appreciated.

Did you talk to your Telco, they should provide you all relevant settings for your T-1, framing, linecoding etc......
These settings differ Telco to Telco. Because of your up, down status one possible reason for your trouble could be the framing.
There is a signal reaching the interface but thats all, no keep alives are being sent. Ahhhhh, did you try using the "frame-relay map" command to map a remote DLCI to the remote IP ?

frame-relay map IP x.x.x.x dlci

Turns out the technician that installed the circut was *cough* new.....

There was no fram relay encapsulation....it was a direct point to point (PPP) setup.....routers are fine now.....all i have to figure out now is how to get the router to see the internet since it sits on the ethernet....oh well...another post....

Simply add a default route pointing to the local firewall
  ip route 0.0.0.0 0.0.0.0 <ip of firewall>
got it....that's what I get for asking before I search....
