An ability to compress packets is announced from a customer edge router (CE) to other CEs through a routing protocol packet. An announcement of that ability is received from another CE through a routing protocol packet. A compression technique is then matched. The CE receives compression information from the other CE in a routing protocol packet, and determines that a compression technique identified therein matches any compression technique the CE is programmed to use. The CE then flags packets transmitted from/received by the CE to be compressed/decompressed according to the matched compression technique. Alternatively, the CE may match by transmitting compression information identifying a compression technique to the another CE in a routing protocol packet; the another CE receives the routing protocol packet and determines that a compression technique identified in the compression information of the routing protocol packet matches any compression technique the another CE is programmed to use.

What is claimed is: 1. A method comprising:announcing, in a first routing protocol packet transmitted from a first customer edge router to at least a second customer edge router in a network, an ability to compress payloads of packets;receiving compression information from the second customer edge router in a second routing protocol packet, the compression information identifying a compression technique supported by the second customer edge router, wherein the first and second routing protocol packets are BGP (border gateway protocol) packets;determining a matched compression technique by determining whether the compression technique identified in the compression information matches any compression technique supported by the first customer edge router;identifying, in a routing table at the first customer edge router, the matched compression technique as applicable to routes that include the second customer edge router; andflagging, based on the routes identified in the routing table, packets transmitted from the first customer edge router to the second customer edge router for compression of payloads, but not headers, of the packets in accordance with the matched compression technique.
