2911 Router with PPP and LAN config

[ccaldwell2]

Need some guidance on this one..

I have a (2) 2911 routers connected to a external CSU/DSU between the two sites, both with 3 gig ports.

2911 Router (Local Router):

gig 0/0 used for PPP to remote site (using external CSU)

*gig 0/1 interface configured for local network traffic172.27.1.0 /28 out of gig 0/0

*route has been added to allow LAN traffic to Remote site

2911 Router (Remote site):

gig 0/0 used for PPP to local site (using external CSU)

gig 0/1 connected to hub which has 5 hosts (10.7.1.0 /24)

gig 0/2 connected to server is data center (10.7.1.0 /24)

Can this config be done on the remote site router?

It's not clear what you are asking. Can you clarify ?

One thing to be noted is that gi0/1 and gi0/2 on the remote site router cannot both be in the 10.7.1.0/24 subnet. You cannot assign 2 ethernet interfaces on the same router into the same subnet.

Here is the issue..

There is a server on one side of the building, and the hosts are down the hall (connected to a hub).

My router is located in the data center, and my connectivity between them is limited to patched fiber and then thru a transceiver to copper at the 2911 router.

They are all configured for the same subnet, and I need them to communicate.

Can I create a VLAN on the router and encapsulate the gig 0/1.1 (server conn.) and gig 0/2.1 (connection to the hub)?

You could use subinterfaces on one of the 2911 interfaces if you had a L2 switch connected to that interface.

I don't think you can allocate the inbuilt interfaces to a vlan ie. make the interfaces switchports at L2.

To be perfectly honest if you only have 5 hosts on the hub by far the easiest solution is to simply readdress them into a different subnet and then use both gigabit interfaces on the 2911 and route between the hosts and the server. Much easier.
