A method, system and computer readable medium for advertising and interoperating Layer 2 VPN services from an access node to a core network. The method can include executing, using one or more processors, a routing protocol on an access node to establish adjacency with a core network node in an access mode. The method can also include mapping, using the one or more processors, an access network Layer 2 service identifier to a core network service identifier. The method can further include advertising, using the one or more processors, a mapping for the L2VPN service to the core network node. The method can also include sending, using the one or more processors, network traffic from the access node to the core network node without core network encapsulation.

Layer 2 VPN service advertisement from access nodes to a core network

A method, system and computer readable medium for redistributing routes in backbone edge bridge multi-chassis link aggregation group topologies between two routing protocols is described. The method can include learning, at a first node and a second node, a first routing table entry originating from a first side of a network and being received in a first protocol and creating, at the first node and the second node, and generating second routing entry information corresponding to the first routing table entry, in a second protocol different from the first protocol. The method can also include exchanging the second routing entry information between the first node and the second node. The first node and/or the second node add the second routing entry information to the routing table when the first routing entry is not present in the routing table and ignores the second routing entry information when the first routing entry is present in the routing table.
