Hi I'm trying to configure a EoMPLS on 2 different router and enable traffic on a VRF.
So what I want to do is:
R1----R2----R3
R1 is on a Routing Area and R3 is on another one, all three Router know each other witch OSPF.
The traffic from R3 come on my R1 Area's witch EOMPLS and this traffic have to be direct in a VRF on R1 without any redirection from Global routing table R1 in to VRF.
My hope I give to you a clear vision of what I want to do.
Someone can give some good tips to implementing that.
Below Some configuration realized on GNS3
R1
interface GigabitEthernet4/0
mtu 4470
no ip address
no negotiation auto
no keepalive
!
interface GigabitEthernet4/0.234
encapsulation dot1Q 234
xconnect 3.3.3.3 234 encapsulation mpls
R3
interface GigabitEthernet4/0
mtu 4470
no ip address
no negotiation auto
no keepalive
!
interface GigabitEthernet4/0.234
encapsulation dot1Q 234
xconnect 7.7.7.7 234 encapsulation mpls
R1#sho mpls l2transport vc detail
Local interface: Gi4/0.234 up, line protocol up, Eth VLAN 234 up
Destination address: 3.3.3.3, VC ID: 234, VC status: up
Output interface: Gi2/0, imposed label stack {17 16}
Preferred path: not configured
Default path: active
Next hop: 192.168.0.2
Create time: 06:58:11, last status change time: 00:45:08
Signaling protocol: LDP, peer 3.3.3.3:0 up
MPLS VC labels: local 17, remote 16
Group ID: local 0, remote 0
MTU: local 4470, remote 4470
Remote interface description:
Sequencing: receive disabled, send disabled
VC statistics:
packet totals: receive 0, send 0
byte totals: receive 0, send 0
packet drops: receive 0, seq error 0, send 0

What IOS version are you running? I remember GNS3 images not being too friendly when asked to forward traffic over l2vpn
CRS1000v and ASR9kV both support l2vpn at least at control plane.
Thanks, L.

Yes is true GNS3 it's not so friendly but at the moment everything work fine, the real Hardware, support the configuration with:
7600-SIP-400
7600-SIP-200

Hey thanks for confirming.
when you refer to a VRF, is that a L3VPN or just a VRF lite? When it comes to MPLS services you need a L2 AC; that is your interface to the CE. The traffic that travels inside a l2vpn is layer 2 by definition, is it that traffic that you want to associate to a vrf?
Thanks, L.
