g
gated.conf(4) gated.conf(4)
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 non-local 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 BGP global trace options. (See Trace Statements and the BGP specific tracing options
below.)
Tracing options
Note that the state option works with BGP, but does not provide true state transition information.
Packet tracing options (which may be modified with detail, send and recv):
packets
All BGP packets
open
BGP OPEN packets which are used to establish a peer relationship.
update
BGP UPDATE packets which are used to pass network reachability information.
keepalive
BGP KEEPALIVE packets which are used to verify peer reachability.
The ICMP Statement
On systems without the BSD routing socket, gated listens to ICMP messages received by the system.
Currently gated only does processing on ICMP redirect packets, but more functionality may be added in
the future, such as support for the router discovery messages. Processing of ICMP redirect messages is
handled by the redirect statement.
Currently the only reason to specify the icmp statement is to be able to trace the ICMP messages that
gated receives.
The ICMP statement
icmp {
traceoptions trace_options ;
}
traceoptions trace_options ;
Specifies the tracing options for ICMP. (See Trace Statements and the ICMP specific tracing options
below.)
Tracing options
Packet tracing options (which may be modified with detail and recv):
packets
All ICMP packets received.
redirect
Only ICMP REDIRECT packets received.
routerdiscovery
Only ICMP ROUTER DISCOVERY packets received.
info Only ICMP informational packets, which include mask request/response, info
request/response, echo request/response and time stamp request/response.
error
Only ICMP error packets, which include time exceeded, parameter problem, unreachable and
source quench.
