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

clauses may specify any number of neighbor clauses.

Any parameters from the neighbor subclause may be speciﬁed on the group clause to provide

defaults for the whole group (which may be overridden for individual neighbors). In addition, the

group clause is the only place to set the following attributes:

peeras

Identiﬁes the autonomous system number expected from peers in the group. If not

speciﬁed, it will be learned dynamically.

localas

Identiﬁes the autonomous system which GateD is representing to the group. The

default is that which has been set globally in the autonomoussystem statement.

This option is usually only used when masquerading as another autonomous system

and its use is discouraged.

maxup

Speciﬁes the number of neighbors GateD should acquire from this group. The default

is to acquire all of the neighbors in the group. GateD will attempt to acquire the ﬁrst

maxup neighbors in the order listed. If one of the ﬁrst neighbors is not available, it will

acquire one further down the list. If after start-up GateD does manage to acquire the

more desirable neighbor, it will drop the less desirable one.

neighbor neighbor_address

Each neighbor subclause deﬁnes one EGP neighbor within a group. The only part of the sub-

clause that is required is the neighbor_address argument which is the symbolic host name or

IP address of the neighbor. All other parameters are optional.

preference preference

Speciﬁes the preference used for routes learned from these neighbors. This can differ

from the default EGP preference set in the egp statement, so that GateD can prefer

routes from one neighbor, or group of neighbors, over another. This preference may be

explicitly overridden by import policy.

preference2 preference

In the case of a preference tie, the second preference, preference2 may be used

to break the tie. The default value is 0.

metricout metric

This deﬁnes a metric to be used for all routes sent to this neighbor. The value over-

rides the default metric set in the egp statement and any metrics speciﬁed by export

policy, but only for this speciﬁc neighbor or group of neighbors.

nogendefault

Prevents GateD from generating a default route when EGP receives a valid update

from its neighbor. The default route is only generated when the gendefault option is

enabled.

importdefault

Enables GateD to accept the default route (0.0.0.0) if it is included in a received EGP

update. If not speciﬁed, the default route contained in an EGP update is ignored. For

efﬁciency, some networks have external routers announce a default route to avoid

sending large EGP update packets.

exportdefault

Enables GateD to include the default route (0.0.0.0) in EGP updates sent to this EGP

neighbor. This allows the system to advertise the default route via EGP. Normally a

default route is not included in EGP updates.

gateway gateway

If a network is not shared with a neighbor, gateway speciﬁes a router on an attached

network to be used as the next hop router for routes received from this neighbor. This

option is only rarely used.
