Configuration Guide
When the protocol argument is set to BGP, the keyword allow-ibgp is optional.
Whereas the import-route bgp command redistributes only EBGP routes, the
import-route bgp allow-ibgp command redistributes IBGP routes in addition and as
such, must be used with cautions.
If no metrics is specified for redistributing a route, the default metrics will be used. The
default value is 1.
3.2.6 Configuring Route Filtering
While receiving, advertising, and redistributing routes, the router may filter routes
according to ACL, IP-prefix list, and/or routing policy.
Perform the following configuration in RIP view.
I. Configuring RIP to filter the received routes
With the filter-policy import command, RIP filters the routing tables sent from
neighbors. The rejected routes do not appear in the local routing table.
