[f-nsp] Problem Trunking Between Cisco/Foundry/Cisco

[System Support]

I am experimenting with a Foundry NI-MLX-4.

I have a fast-E trunk to a Cisco router on eth 3/3 and another fast-E trunk
to a Cisco 3750 on eth 3/20

The router has IP address 10.0.1.1/24

The MLX router has IP address 10.0.1.2/24

The 3750 has IP address 10.0.1.3/24

>From the MLX-4 I can ping both Cisco devices, but from either Cisco I cannot
ping the other.

Spanning tree on the devices show the proper ports are forwarding, but no
traffic is passing.

Any ideas ?
