Do I still need an external router to route between different VR , as teh extreme switch has one mac

Rod_Robertson2 — Tue, 24 Jan 2017 23:16:00 GMT

I have a customer who needs to route between virtual routers , normally I would do this , with some sort of extrenal routing box ( firewall or router )
I now have a customer who wants to do this on teh switch , I thought this was not possible as teh extreme switch has only one mac. I am about to upgrade to 16.1.3.6-patch1-10 , if that is any help.

Hi Rod, you can accomplish that using static routing.

Please see the article below:

OK like the gtac knowledge , though to be honest dont like static routes.. if there are multiple networks within the vr's , then there will need to be a static route between each and every network both directions.. that's assuming that the networks within the vr are not contiguous .. ( within a /8 /16 address range )
So we come back to an external router , with basically a routing protocol.. OSPF area 0.0.0.0 and various other area's to match the Vr's

Yes, current the inter VR is pretty limited. I have raised aGTAC feature request to allow user-VRs to do static routing tracking (e.g. flow-redirect) which will be beneficial if you are dealing with different ISPs.
