packetsize maxpacketsize
This defines the expected maximum size of a packet that EGP expects to receive from this
neighbor. 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 clauses may specify any number of neighbor clauses.
Any parameters from the neighbor subclause may be specified on the group clause to pro-
vide defaults for the whole group (which may be overridden for individual neighbors). In addi-
tion, 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 prefer-
ence 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
