version version
Specifies the version of the BGP protocol to use with this peer. If not specified, the highest sup-
ported version is used first and version negotiation is attempted. If it is specified, only the
specified version will be offered during negotiation. Currently supported version are 2, 3 and 4.
passive
Specifies that active OPENs to this peer should not be attempted. GateD should wait for the peer
to issue an open. By default all explicitly configured peers are active, they periodically send
OPEN messages until the peer responds.
sendbuffer buffer_size
recvbuffer buffer_size
Control the amount of send and receive buffering asked of the kernel. The maximum supported
is 65535 bytes although many kernels have a lower limit. By default, GateD configures the max-
imum supported. These parameters are not needed on normally functioning systems.
indelay time
outdelay time
Used to dampen route fluctuations. Indelay is the amount of time a route learned from a BGP
peer must be stable before it is accepted into the gated routing database. Outdelay is the
amount of time a route must be present in the gated routing database before it is exported to
BGP. The default value for each is 0, meaning that these features are disabled.
keep all
Used to retain routes learned from a peer even if the AS paths of the routes contain one of our
exported AS numbers.
showwarnings
Causes GateD to issue warning messages when receiving questionable BGP updates such as
duplicate routes and/or deletions of nonexisting routes. Normally these events are silently
ignored.
noauthcheck
Normally GateD verifies that incoming packets have an authentication field of all ones. This
option may be used to allow communication with an implementation that uses some other form
of authentication.
noaggregatorid
Causes GateD to specify the routerid in the aggregator attribute as zero (instead of its routerid)
in order to prevent different routers in an AS from creating aggregate routes with different AS
paths.
keepalivesalways
Causes gated to always send keepalives, even when an update could have correctly substituted
for one. This allows interoperability with routers that do not completely obey the protocol
specifications on this point.
v3asloopokay
By default gated will not advertise routes whose AS path is looped (with an AS appearing more
than once in the path) to version 3 external peers. Setting this flag removes this constraint.
Ignored when set on internal groups or peers.
nov4asloop
Prevents routes with looped AS paths from being advertised to version 4 external peers. This can
be useful to avoid advertising such routes to peer which would incorrectly forward the routes on
to version 3 neighbors.
logupdown
Causes a message to be logged via the syslog mechanism whenever a BGP peer enters or leaves
the ESTABLISHED state.
ttl ttl
By default, GateD sets the IP TTL for local peers to one and the TTL for nonlocal peers to 255.
This option mainly is provided when attempting to communicate with improperly functioning
routers that ignore packets sent with a TTL of one. Not all kernels allow the TTL to be specified
for TCP connections.
traceoptions trace_options
Specifies the tracing options for this BGP neighbor. By default these are inherited from group or
