[c-nsp] Link Status Not Transmitted, Another way to drop the interface/ route?

[Martin Robinson]

Hello Steve,

Looks like it could be a DLCI to VPI/VCI mapping problem. Firstly make
sure your frame relay encapsulation is correct, most SP's do not support
Cisco encapsulation (try IETF). Then you need to check that you have the
correct LMI type (ansi, cisco, or q933a).

If these are correct then the command "atm ilmi-keepalive <<time>>"
configured on the ATM interface should give you status of the remote
frame interface.

Regards Martin.

Hi all,

I have a situation where we are provided with a Frame Relay service one
end
of a circuit, and ATM the other.

The problem I have is that no matter what, the ATM PVC always stays
up,up,
and therefore when the Frame Relay end of the circuit goes down, we do
not
see this and still try to route packets to them via this interface.

Unfortunately, we do not control the middle pathway between the two so
can't
correct the link status not being transmitted  :(

Other than running something like BGP, or possibly even doing
reachability
via SAA, is their a simpler way to achieve end to end status and drop a
route/ the interface if the criteria is not matched?

Thanks for any help,

Steve
