2810's Core and 2626 as access

[T Harris]

We have a pair of routers that are using VRRP to provide redundancy. Each router is connected to a 2810 and a single link between the two switches exists. VLANs are used. 2626's are used as access switches and each has a single connection to one or the other 2810s.

We would like to provide greater redundancy and have two (up)links from each 2626 - one connected to each 2810 core switch. We were planning on using MSTP and following HPs configuration note - but we have now realised that 2810's don't support IP routing. Anyway way to achieve what I need another way?

Hi,

I don't see why the lack of L3 routing on the 2810's causes you an issue?
What you've described, redundant links from your 2626's to the 2810's using MSTP, should work fine.

Thanks - most helpful. It was the reference to turning on IP routing in this document that got we wondering - why. Do you know why they turn on IP Routing?

The document is just trying to provide an example of a typical complete HP solution (whereas you have seperate routers routing between your VLANs).
You may want to just read through the MSTP setup guides in the manuals as it's quite complete and explains most of the concepts in detail:
