Hi, I am trying to setup EoMPLS over two networks which running different AS number with VPNv4 BGP for MPLS VPN. Connection is something like:
PE1---AS1234----- WAN (bgp w/vpnv4) ------AS5678--PE2
We trying to build EoMPLS between PE1 and PE2. We have send the loopback IP through BGP for xconnect peer at both end. VC is up but can't receive any packet. Problem should be caused by missing label for remote end. There is only two labels when "show mpls l2transport vc detail"
Local interface: Gi0/3.187 up, line protocol up, Eth VLAN 187 up
Destination address: 10.10.135.139, VC ID: 1234, VC status: up
After the packet cross the border, we should need another label to forward the packet to the destination PE like in MPLS VPN. Workaround may be building tunnel between the two PE. But is there any other choice I can do? Thanks.
Thanks Arunkumar. It is good idea. The only problem is we need to setup another ethernet circuit between the two ASBR or do ethernet emulation over the existing STM-1. We will see what we can do on it.
Calvin, from your description it seems you have option B inter AS implemented. this wont give the end-to-end LSP required for ATOM to work.
As a workaround maintaining the same method if you can inject loopback address from IGP into BGP on the local ASBR in each AS and then advertise them on IPv4 to the other AS with a label assigned to the loopback routes.
And when received on the remote AS you will need to inject those received loopback routes into IGP.
This should get your end to end LSP based ATOM VC working.
