Why not use something like RAD's RICi-T3.  I'm sure it would be a whole lot
less money, and much more straight-forward.

Subject: [c-nsp] 7301 w/ bridge-group

Hi-

I am looking at a deployment with a pair of 7301s with two DS-3s
connecting them. The intention is to extend an Ethernet segment from one
port across the two DS-3s to a port on the second 7301. Having used
bridge-groups in the past for high bandwidth applications, I realize
that they perform horribly and everything is process switched.

1) Is my assumption that the NPE-G2 will process switch everything
accurate? Last device I tried this on was a RSP4 based 7500, so I
realize the architecture is very different.

2) Is using L2TPv3 pseudo-wire with the DS-3s running as L3 routed
interfaces going to get better performance on this platform?

3) Did I miss something about bonding serial interfaces and having them
in a bridge group? I can't even fathom how that is supposed to work.

If anyone has other suggestions, I'm open to them.

David
