In this post we demonstrate how to configure vlan based
Ethernet over MPLS on Cisco, Juniper and Alcatel-Lucent.
EoMPLS is called l2circuit on Juniper and Ethernet Pipe
(Epipe) on Alcatel-Lucent.
Prerequisites:
MPLS and ldp enabled throughout the network.
Topology:
In this example we have 3 sites and from each site we created
two L2 Circuits one each to remote sites.
On CPEs we have made 2 logical interfaces one each to remote
site.

Alcatel Configuration:
In Alcatel-lucent Ethernet Pipe (EPIPE) is
a layer 2 point-to-point service where the customer data is encapsulated and
transported across a service provider’s IP or MPLS network. EPIPE service is
based on the IETF “Martini Drafts”.
