Help with IP and ATM T1 circuits

I am turning up a new wan on the ATM protocol. And with my current setup I can not ping the ATM interface on the router. Can anyone tell me what I am missing?

Re: Help with IP and ATM T1 circuits

Which IP address are you trying to ping ? I don't see any IPs configured in the config you posted.

Sorry was not the current config.

Here is the section of the current config of the host router and one of the remotes.

Re: Help with IP and ATM T1 circuits

Hi,

Your routers seem to be using old syntax so I'm not sure I'll get it completely right but try the following on the host router (for the remote whose config you posted):

interface ATM0/0/0

description Circuit 14.HCGJ.004342.VADI

ip address 192.168.101.1 255.255.255.0

no scrambling-payload

atm pvc 3 1 32 aal5snap

protocol ip 192.168.101.3 broadcast

Also, I'm not sure if that is the right PVC for that remote...change it to suit.

The remote router config seems okay.

Try that and see how you go.

Actually, I found out how to do this with the version you are using. You need to use

Re: Help with IP and ATM T1 circuits

Actually, I found out how to do this with the version you are using. You need to use a map-list to specify the IP address of every remote router as follows:

interface ATM0/0/0

description Circuit 14.HCGJ.004342.VADI

ip address 192.168.101.1 255.255.255.0

no scrambling-payload

atm pvc 3 1 32 aal5snap

atm pvc 5 1 33 aal5snap

atm pvc 6 1 34 aal5snap

atm pvc 4 1 35 aal5snap

no atm ilmi-keepalive

map-group PVCMap

!

map-list PVCMap

ip atm-vc broadcast

! create one line for every remote router

For example, one possible config could be:

map-list PVCMap

ip 192.168.101.3 atm-vc 3 ! assuming 1/32 goes to the remote site whose config you attached

Pls do remember to rate posts...

Re: Help with IP and ATM T1 circuits

I may try that Paresh.

The SE on the cisco case wanted to know why I was using the "OLD command" I have all the pvc's working with IP acept on remote. The SE had me us the " pvc vpi/vci" command to get to the pvc configuration level. then using the broadcast command all the multi point pvc's sh using the "sh atm map" command. So far the "sh atm map" command does not show the pvc to ip maping on the point to point interfaces but ping works and I can pass traffic.

I think I may have recieved the wrong vpi/vci info for the remote that can not talk to the host. It can talk to the other remotes. ( full mesh pvc's).
