Hi All.
Consider the following scenario.
Node A. --->Switch---->C7609--{...Internet..}--C7200--NodeB
Node A has IP 192.168.1.1
Node B has IP 192.168.1.2
So far I have a working gre tunnel between the routers.
How do I get Node A to talk to Node B ?
Any help appreciated.
Thanks,
Ken

Hi Ken,
Is this a trick question or are you going to post the config?

Consider the following topology
Router1 [S0](64.45.15.17) ------ Internet -------(65.17.89.11)[S0]Router2---192.168.1.0/24
|_(10.0.0.1)_____________GRE Tunnel____________________(10.0.0.2)_|
Router1
*******
interface Tunnel0
ip address 10.0.0.1 255.255.255.252
tunnel source 64.45.15.17
tunnel destination 65.17.89.11
ip route 192.168.1.0 255.255.255.0 Tunnel0
ip route 65.17.89.11 255.255.255.255 Serial0
Router2
*******
interface Tunnel0
ip address 10.0.0.2 255.255.255.252
tunnel source 65.17.89.11
tunnel destination 64.45.15.17
ip route 64.45.15.17 255.255.255.255 Serial0
hope this helps.

I have the basic tunnel between the cisco routers up but i suspect my whole approach seems wrong.
Node A. --->Switch---->C7609--{...Internet..}--C7200--NodeB
Node A has IP 192.168.1.1
Node B has IP 192.168.1.2
Unfortunatelly the iterfaces are all ethernet and it is the nodes that i need to get to talk.

I have decided to go with an EoMPLSoGRE setup.
So far I have:
the gre tunnel up
the mpls l2transport vc up
the setup is:
asr1004====GRE====c7206
the xconnect is on ge interfaces in the 2 boxes and the ce is a pc on one end and a switch on the other.
My challenge is the vc does not seem to pass any traffic. Specifically when I sh mpls forwarding-table I see no bytes switched.
Also on the c7200 the outgoing interface is 'none'
All assistance will be appreciated.

The configuration for this is relatively straightforward, so if the code and platform you're operating support the feature you should be fine.
-Configure a GRE Tunnel between your PEs.
-Enable MPLS over Tunnel
-Establish Routing over Tunnel for LDP endpoints
-Verify LDP adjacency
-Configure Pseudowire Class with 'encapsulation mpls'
-Configure the xconnect on the Attachment Circuit.
Validate the state of your vc with the 'show mpls l2transport vc' command.
