Configuring Internet Protocol (IP) routing

Statements of the gated configuration file

The configuration statements and the order in which these statements appear divide gated.conf into:

options statements
interface statements
definition statements
protocol statements
static statements
control statements

Entering a statement out of order causes an error when parsing the configuration file.

Two other types of statement do not fit in these categories:

%directive statements
%trace statements

These statements provide instructions to the parser and control tracing from the configuration file. They do not relate to the configuration of any protocol and may occur anywhere in the gated.conf file.

Following is a summary of the configuration statements that may be used in the gated configuration file. More detailed definitions and descriptions of each of the eight classes of gated statements follow in separate sections.

%directory: sets the directory for include files
%include: includes a file into gated.conf

options: defines gated options

Interface statements include:

interfaces: defines gated interfaces

Definition statements include:

autonomoussystem: defines the AS number
routerid: defines the originating router (BGP, OSPF)

Protocol statements include:

ospf: enables OSPF protocol
egp: enables EGP protocol
bgp: enables BGP protocol
redirect: configures the processing of ICMP redirects
snmp: enables reporting to SNMP

static: defines static routes

Control statements include:

import: defines which routes to import
