Figure 6-1. EGP Connection between Two Autonomous Systems
Running RIP
The Bay Networks implementation of EGP complies with RFCs 827 and 904. It
runs over the same LAN and WAN media/protocols that IP runs over, including
Ethernet, Token Ring, Synchronous, Wellfleet Proprietary Synchronous, Frame
Relay, SMDS, X.25 (DDN, PDN, Pt-to-Pt), ATM PVC, FDDI, T1, E1, HSSI, and
PPP.
An EGP router has the following capabilities:
• It acquires EGP neighbors.
• It determines neighbor reachability.
• It exchanges network reachability information with its neighbors.
Each of these capabilities has an associated phase in EGP: the Neighbor
Acquisition phase, the Neighbor Reachability phase, and the Network
Reachability phase, respectively. The following three sections explain each phase.
Note: EGP assumes that each advertised network is a natural class network
(A, B, or C) based on its high-order bits. EGP cannot advertise or interpret
subnets or supernets.
