Hi,
As suggested RIPv2 would be better than manual routing but beware of the
convergence time with this protocol, this could take up to 5 minutes but it's
automatic ;-)
SecureStack B3/B5/C3/C5 and G3 included inter-vlan routing and RIPv2 without
licence. E1 is ready and much.
Working with a multi-point routed Campus instead of single-point
routing/switching one, allow you to have easy maintenance window and avoid L2
issue to propagate to any sites.
They are pros and cons but that depend on how many issues you have encountered
until now with single-point architecture and how hard it is to planify
maintenance operation actually. You should consider IP migration plan by site,
routing compatible products, etc.

If I'm reading your original post correctly, you will have an S4 chassis at
your core, with G3s as building distributors and E1 switches as edge switches.
Since you mention a budget restraint on licences, I'm guessing that you intend
to do your distributed routing on the G3s. (Both the E1 and S4 have standard
OSPF).
When I have been in a similar situation, (eg using gold DFEs as routers sans
licence ), I have used RIP v2 in preference to statics. RIP is sub optimal for
a couple of reasons, but it beats statics hands down IMHO.
One other possibility you have is to run your load balancing on the S4. They
handle this work very well, and that will certainly cure your ARP flood.

We had an issue with the Microsoft NLB that was causing an arp flood.
We had other issues that I cannot fully explain at this point. Our network has
been very stable for many years. In essence, this NLB problem had been going
on for quite some time, however with additional devices hitting OWA and our web
server the problem finally hit a breaking point. The budget constraints are
tied to purchasing the additional licenses for routing.

What was the issue that caused you to re-think your routing strategy?
And what budget constraint implies that you must use static routes as opposed
to a dynamic routing policy?

Hi all,
We have a 99% Enterasys network. At our core we are replacing our dfe
blades with an S4. Three years ago, I move all of the routing from the edge
devices (E1's) to the core. Everything had run fine until an issue occurred
recently. Now the thought process has been to move the routing back out to the
edge devices using static routes. I am looking for external advise on the pros
and cons of making this change.
We have 40+ subnets/vlans. The remote buildings will have a G3 at the entrance
with 2 - 3 E1's stacked behind. At some point in time, we have had up to 13K
devices connect to our network.
Thanks,
Sean
