Cisco 2821 Vlan cleanup

Currently we use a Cisco 2821 at the gateway for all the vlans and for the vlan routing.  It also is our internet endpoint for vpn and tunnels.  We are currently running a slew of dell 6200 series switches that we are replacing with cisco 2960's, and we also have 2 new 4900 series that are now going to handle all the vlans.  My question is what do i need to do to the 2821 to clean up the things it don't need anymore.  Do i need any new routes to point to vlans on the 4900?

Thanks

attached are the configs.

Yes you will basically need routes added on the router to point to the different vlan subnets on the new switch.

they would have to point to  the .1 address>


for example vlan 32 is  10.15.32.x

so

ip route 10.15.32.0 255.255.255.0 10.15.32.1

is that correct?


as far as cleanup, is it just as simple as removing all the subinterfaces currently on there for the vlans?

Well not exactly. It depend on what vlan the inside interface of your router sits on.

So if the router sits on vlan 32 and the 10.15.32.1 address is the SVI on the new switch then your route would be like:

ip route 10.15.31.0 255.255.255.0 10.15.32.1
ip route 10.15.33.0 255.255.255.0 10.15.32.1


and so on. They will all have a next hop of 10.15.32.1

You will not need a router for .32 because the router already sits on the vlan.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

And yes, you will create the SVI's on the switch to correlate with the subinterfaces, then remove the subinterface on the router.

why wouldn't you make the next hop the correlating svi on the 4900? or at that point it doesn't matter as long as it hits one of them?

SouljaCommented:
How would it get to that specific SVI if it doesn't know how to get there?

 See you will have to treat the router like a host somewhat. It's sitting in the 32 vlan, so it needs it's next hop to be the svi of the 32 vlan in order to get to the other vlans.
