The AS number 303 is defined early because it is a definition statement and must
occur before the first protocol statement. EGP is enabled by the yes keyword in
the EGP statement. This statement also defines the following EGP parameters:
•
Packetsize parameter, which defines the initial size of update packets
accepted.
• Group clause, which sets parameters for all of the EGP neighbors in the
group.
• Minhello and minpoll , which set the protocol timers.
The first export statement directs GATED to use EGP to advertise the network
(136.66.0.0) to the Internet. This is the address of the network, not of a gateway.
The second export statement is used to announce the default route to subnet
136.66.12.0 with a metric of 3.
