The syntax of the sitelocal configuration statement is as follows:
sitelocal (allow|restrict);
where:
allow Specifies that propagation of site-local routes is allowed.
restrict Specifies that the RIPng router must not propagate the site-local routes.
Redistributed Routes for RIPng
The defaultmetric statement specifies the metric to be used when advertising routes through the RIPng
protocol. This is applicable for the routes learned from other protocols.
If no value is specified, the default value is 1. The metric specified in the export policy overrides this
configuration.
The syntax of the
defaultmetric
configuration statement is as follows:
defaultmetric metricvalue ;
where metricvalue specifies the default metric value.
Maximum Routes for RIPng
The maxroutes statement specifies the maximum routes that a RIPng router can store in its routing table.
By default, this is 30000.
The syntax of the maxroutes configuration statement is as follows:
maxroutes numb-of-routes;
where numb-of-routes specifies the maximum routes that a RIPng router can store in its routing table.
Route Filtering Configuration for RIPng
The following statement is used to route filters.
The syntax of the route_filter configuration statement is as follows:
route_filter filter-name {
[prefix prefixlength;]
[host host-address ;]
[all;]
};
A route filter can have a combination of multiple host routes and multiple net routes. If
all
configuration statement is specified, host and net entries must not be specified. This route filter can be
specified in the filter configuration statements. See the filter statement in the Route Filtering
Configuration for RIPng section.
Route Aggregation for RIPng
Route aggregation is the process of merging two or more routes to form a single route on the basis of
matching bits in each route. It reduces the number of routes in the RIPng route update message. The
receiving RIPng neighbor router installs the aggregate route in the kernel routing table. Hence, route
aggregation reduces the number of routes in the kernel routing table.
The
aggregate configuration statement can be used to generate aggregate routes. If this statement is
not specified in the configuration file, RIPng router does not perform route aggregation.
The syntax of the
aggregate configuration statement is as follows:
aggregate {
[prefix prefixlength
[preference preference-value][restrict]];
};
where:
prefix prefixlength Specifies the routes that can be aggregated and its prefix length.
preference preference-value
Specifies the preference value of the aggregate route. By default, the value is 130.
