My EIGRP knowledge is limited. I was wondering if one of you Cisco
geniuses could help me with my configuration. First I have a scenario
here. My corporate office has a Layer 3 Switch with multiple VLANs
configured, however they want to setup a router at a DR Site. They
purchased two routers which will be connected via a DS3 for transport
to the DR Site. Is it possible to have a VLAN - 10.2.0.0 configured on
the L3 Switch, and have it route over and be accessible at the DR Site.
I would use say 10.4.2.1 and 10.4.2.2 for the Serial Interfaces, is it
possible to use EIGRP in such a scenario. I know my question is vague,
but if anyone can help, that would be great.

Some switches also support routed interface

Pick a test port and see if 4506 will accept the following

int <interface>
no switchport
ip address ....
exit

sho int <interface> status ! see if it says 'routed"




#sh int fa 11/1 switch
Name: Fa11/1
Switchport: Disabled


#sh int fa 11/1 status

Port Name Status Vlan Duplex Speed Type
Fa11/1 connected routed a-full a-100
10/100BaseTX




#sh run int fa 11/1
Building configuration...

Current configuration : 68 bytes
!
interface FastEthernet11/1
ip address x.x.x.60 255.255.0.0
end

If you want to extended a VLAN (10.2.0.0/16) from your HQ to the DRP
site, then you would have to bridge that VLAN across the DS3 link which
is possible
