Nortel ELAN: can it be routed ????

Yes it can. You need to be sure they put some sort of access list so that not everything can reach that subnet range. Keep it in house.
We have a site that has OTM/TM here at the main corporate site. Locally we have 5 PBX's, one in Dallas, one in Florida and soon to have one in DC area. Only one of these switches are in the same building and this is used to manage them all.
Some of you are going to go DUH of course they are not in the same building. Well....in one of the buildings we have 2 CS1000M Multi Group switches. One a 3 group switch and the other a 4 group switch.

The latest survey shows that 3 out of 4 people make up 75% of the population.

nortel says don't do it.. i have and it works.. the main problem nortel saw early was broadcast traffic causing hits. i know vlan segmentation blocks all traffic from other vlans... in one case (a bps 2000 switch) that was not the case...
if i needed to do it here i would, but i would also check that vlan traffic with a data sniffer for a few days to insure the isolation.. think about it, one clown plug something into the wronge port and you'll end up chasing it.

The E-LAN is indeed routable, as has been noted. I have 5 locations: London, Chicago, New York, 2 in Washington DC, and all are routed, and members of the same vlan.
Station management is done through 1 central TM 3.1 server that has access to the E-LAN vlan.
We do not explicitly block access to the E-LAN vlan, and have not had any problems with broadcast traffic in 2+ years.

The problem in the past was that the customers wanted to place it on their lan. Router will stop broadcasts and that is how Nortel wanted and wants it set up to this day, behind a router.

FYI it sounds like different folks are talking about different things here.
Routable ELAN means it can be hit from other subnets in the network - therefore it is behind a router.
Other folks are taking about using VLANS to extend the ELAN over a large geographic area (all the same subnet though)
The second example can also be routable if needed, and BOTH configurations are 100% supported by Nortel for support.

ELANs that are on the same subnet can be routed. But the have to be in the SAME subnet. That is for release 4.5 and earlier. With Release 5.0 you can have the ELAN in different subnets that route between each other. The reason for VLANS is to keep broadcast traffic down.
If you are going to use Geographic Redundancy, have different call servers in different areas for survivability, you MUST have different ELAN subnets. You must use the same node ID for all the Sig Svr Nodes. It gets quite involved setting it up and not enough room here to explain.

Yeah, that was a bad mistake from WAY back. the default 137.135.0.0 was actually a lab switch in Nortel Santa Clara in a fcility that is now closed. Nortel still owns that Class B address, and I have heard rumors that a machine shows up on the internet at that address every once in a blue moon. That may just be a myth though.
In any case, you will need to assign valid local IP aadresses from you IT department. You can do NAT with private IPs behind it, but that I think is more complex.
