Self-organizing and scalable MPLS VPN transport for LTE

摘要

In one embodiment, an access node of a network may receive a message that is destined for a particular address. The access node can determine that it does not have a border gateway protocol (BGP) label switched path (LSP) mapped for the particular address. The access node can further trigger an aggregation node to update outbound route filtering (ORF) to permit advertisements for the particular address. In response to the updated ORF of the aggregation node, the access node can receive via advertisements a BGP forwarding equivalent class (FEC) for an LSP mapped to the particular address. The access node can further transmit messages destined for the particular address from the access node to a subsequent node of the LSP according to the BGP FEC for the LSP.

1. A method, comprising:
receiving a message at an access node of a network, the message destined for a particular address; determining that the access node does not have a border gateway protocol (BGP) label switched path (LSP) mapped for the particular address; triggering an aggregation node to update outbound route filtering (ORF) to permit advertisements for the particular address; receiving, via advertisements in response to the updated ORF of the aggregation node, a BGP forwarding equivalent class (FEC) for an LSP mapped to the particular address; and transmitting messages destined for the particular address from the access node to a subsequent node of the LSP according to the BGP FEC for the LSP.
