| Exterior
Gateway Protocol (EGP) is a
protocol for exchanging routing information between two neighbor
gateway
hosts (each with its own
router) in a network of autonomous systems. EGP is commonly used between
hosts on the Internet to exchange routing table information. The routing
table contains a list of known routers, the addresses they can reach, and a
cost
metric associated with the path to each router so that the best
available route is chosen. Each router polls its neighbor at intervals
between 120 to 480 seconds and the neighbor responds by sending its complete
routing table. EGP-2 is the latest version of EGP. |
