Re[2]: Routed over this thing?

Hi Eric,

Exactly right on all counts. If I'm getting this right, connections
to the end users with single IP's with work just fine without RBE, just
doing AAL5 encapsulation. But to route to them, RBE has to be
configured?

The CPE is BroadMax LinkMax HSA-300A. It is supposed to work with
LLCbridging.

Today, after verifying that this CPE worked as a bridge and
passed traffic to the one IP of...
ip route 66.250.201.4 255.255.255.255 ATM1/1/0.320
We configured it for LLC Bridge and assigned that IP 66.250.201.4 to the WAN side of the CPE.
And then did this..
ip route 66.250.202.0 255.255.255.248 66.250.201.4

But it didn't work, couldn't reach 66.250.201.4 WAN address at all...
no arp, no routing... so maybe this is due to RBE not configured.
If that's the case, does what was attempted look reasonably sane?

Thanks,

Todd
