Re: [mpls-linux-general] MPLS and ATM

[James R. L. <jl...@mi...>]

Hello,

What is the atm index of your ATM card?

cat /proc/net/atm/device

It shows up as the Intf.

When creating your atm interface (via atmarp -c) the index in the name
needs to match that of the index from above.

Example:

If the atm card index (from /proc/net/atm/device) is 3

atmarp -c atm3

I know this is a kind of a ridiculous rule, but due to the nature of
ATM for Linux it is a requirement.  Someday I'll get a around to re-writing
the way ATM interfaces are handled on Linux ...

Let me know if this still doesn't help.

Jim
