Hi all,
We're running a cluster of SRX-240's and are in the process of migrating our core routers to Extreme Networks.
One of the goals is to run a multi-VLAN trunk between the SRX-s and Extreme router (stack). This is of course simple to a accomplish using redundant interfaces with VLAN tagging. But one of the VLANs is already defined on the SRX (a DMZ), so switching is needed.
As far as I can tell I need to define the two interfaces from the nodes of the SRX connecting to the core routers as ethernet-switching with port mode trunk and define VLAN's. I did a test setup, added a switching fabric link between the nodes. This works, but in contrast to using redundant interfaces, both interfaces on the respective nodes are active and switching traffic among them. So I probably need spanning-tree to avoid loops? Or is there a way to use the an active-active setup?
Is this the right way to do this? Any input is greatly appreciated!
Regards,
Steve
