Vlan Tagging should be enabled between the two switches.

Your question is vague, please provide more detail so we do not assume when trying to assist your issue.

Hi,
I have a network with baystacks 470 e passports 8600,
I have two datacenters in diferent sites, the servers must have in the same network .

You can do this without an issue, as long as you can use VLANs on all the gear that make up your network data flow to both sites. Meaning the router that handles the communications can do vlanning. Your best be in this scenario, is your 8600s handle your WAN ips.

From there you have to setup is vlan tagging across your wan link. This will allow you use the same subnet (Vlan) at both locations.

If you have a firewall or router between these two sites that do not handle vlan tagging, then this will not work for you. You will not be able to split the same subnet across the two sites. (Not that I know of...)


8600s

470---8600---(tagged packets)---8600---470

If you need more info on how to set this up, please let me know. I will shoot you more specifics.

470---8600---(tagged packets)---8600---470
| |
8600-------8600-----------8600
and if the link who have the taged packets broken ,how can i do for the other link work us a backup.

As you've probably already realized you'll need to have the VLAN on the primary and backup paths - probably using VLAN tags. Of course this would cause a loop for that VLAN, so you'd need to use spanning tree to setup the active/standby relationship - or you could use Nortel's SMLT feature in a 'square' configuration.

Several people in this group are fairly smart about SMLT configurations, but it might be helpful for you to first take a look on Nortel's web site for their SMLT design guides and their 'Converged Campus Technical Solution Guide'. They give examples and configurations similar to your needs.

These links will give you a brief overview of what Anthony is describing. It shows you how you could setup/design a SMLT meshed network.

Tanks to boths,i think is the way to solve my problem.
