Is this a Bell Nexxia PPPoE service (GAS) or ADSL gateway
(HSA)?
If it's GAS you'll also need to terminate the L2TP on a
specific device.

Subject: [cisco-nas] terminating DSL VLANs/Tunnels (spec.
bell nexxia,
canada)


(may be OT in that it doesn't specifically reference a cisco
nas, but it deals
in access provisisioning of sirts so am hoping it will reach
the right audience)

we are about to terminate a 100baset connection from bell
nexxia up here over
which they will be sending 120 tunnels from the various
redback switches to us
spread over 12 VLANs.
this will connect all the various DSL clients to our network
for us to route
traffic out our internet pipe (datacenter).

We are looking at having this terminate into a Cisco 3550
EMI to have all the
VLANs and Tunnel switching and so forth. This would provide
sufficient port
density for the DNS, Radius, and so forth servers wthat will
also occupy the
rack in the datacenter.

Had some brief speculation on this earlier, and before
actually purchasing,
wanted to make sure that this would more than likely handle
our needs. Can
anyone either with first hand experience with Bell or other
such DSL service
links provide some insight and/or recommendations?

thanks

Dave

Both types of connections will be coming over these pipe and terminating at the
switch for routing to the internet. Not understanding your second statement.

What kind of tunnels are you talking about? Are these L2TP tunnels? If
so, the 3550 doesn't support L2TP termination.

good catch, they are L2TP tunnels. VLAN trunking is ISL.

As such, the question becomes what do we need to terminate the tunnels in,
recommended setup sort of thing, from the given 120 tunnel count over the 12
VLANs.

Obviously I was hoping the robust and feature-full nature of the 3550 would be a
one shot solution to save on configuration, device number, and rackspace.

Is that 120 tunnel or 120 sessions? If tunnels, how many sessions do
you expect? It sounds like you are looking for both a router and a
switch combined into one. I think the c37xx has a switch module but I
don't know if it has sufficient port density or is the most cost
effective solution for your needs though.
