EGP are called EGP neighbors, and the exchange of HELLO and I-H-U messages is referred to as acquiring

a neighbor. Once the neighbor is acquired, the system polls the neighbor for routing information. The

neighbor responds by sending an update containing routing information. If the system receives a poll from

its neighbor, it responds with its own update packet. When the system receives an update, it includes

routes from the update into its routing database. If the neighbor fails to respond to three consecutive polls,

GateD assumes that the neighbor is down and removes the routes of that neighbor from its database.

preference preference

Sets the preference for routes learned from RIP. The default preference is 200. This preference

may be overridden by a preference speciﬁed on the group or neighbor statements or by

import policy.

defaultmetric metric ;

Deﬁnes the metric used when advertising routes via EGP. If not speciﬁed, the default value is

255 which some systems may consider unreachable. This choice of values requires you to expli-

citly specify a metric when exporting routes to EGP neighbors. This metric may be overridden by

a metric speciﬁed on the neighbor or group statements or in export policy.

packetsize maxpacketsize

This deﬁnes the expected maximum size of a packet that EGP expects to receive from this neigh-

bor. If a packet larger than this value is received, it will be incomplete and have to be discarded.

The length of this packet will be noted and the expected size will be increased to be able to

receive a packet of this size. Specifying the parameter here will prevent the ﬁrst packet from

being dropped. If not speciﬁed, the default size is 8192 bytes. All packet sizes are rounded up to a

multiple of the system page size.

traceoptions trace_options

Speciﬁes the tracing options for EGP. By default these are inherited from the global trace

options. These values may be overridden on a group or neighbor basis. (See Trace Statements

and the EGP speciﬁc tracing options below.)

group

EGP neighbors must be speciﬁed as members of a group. A group is usually used to group all

neighbors in one autonomous system. Parameters speciﬁed on the group clause apply to all of the

subsidiary neighbors unless explicitly overridden on a neighbor clause. Any number of group
