IMlA Interface problem

steve.kerr
Level 1
Level 1

Hi,

I have a problem with my ATM/IMA subinterfaces in that I can't even ping my local interface from the router despite it showing UP UP.

I am connecting to 3 times E1's using VWIC2 mutliflex cards on a 3825.

I have an ATM aim model and all of the above seem to be up OK.

I am working with my telco to connect remote frame-relay sites in to my core site.

The remote sites stay as frame-relay and my core site has 3 times E1's connected to my telco's ATM switch (a Nortel) as a single 6 meg ATM bundle.

We are trying to migrate my core site from frame-relay to ATM over E1 using the configuration below.

My IMA is UP, and my sub-interfaces are UP UP, but I can't ping my local sub-interface IP address, let alone the remote site IP.

Am I missing some command to map my layer 3 to the layer 2 protocol?

Any other ideas?
