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 - configured on
the L3 Switch, and have it route over and be accessible at the DR Site.
I would use say and 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.
Here is the Diagram Link:

Yes that setup is possible using EIGRP

Re: EIGRP Help
Some switches also support routed interface

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

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

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

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

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

Re: EIGRP Help
If you want to extended a VLAN ( from your HQ to the DRP
site, then you would have to bridge that VLAN across the DS3 link which
is possible

In the diagram that you posted it looks like you are only intending on
having one VLAN at the DRP site - is that the cae and are you sure that
will will not want add others VLANS now or in the future.

Re: EIGRP Help
I'll just use EIGRP then to route. You're right. May want to expand
into the future.
