Importing routes from RIP and redirects

Importing routes from RIP and redirects



   import proto rip | redirect
       [ ( interface interface_list ) | (gateway gateway_list ) ]
       restrict ;
   import proto rip | redirect
       [ ( interface interface_list ) | (gateway gateway_list ) ]
       [ preference preference ] {
       route_filter [ restrict | ( preference preference ) ] ;
   } ;
The importation of RIP and Redirect routes may be controlled by any of protocol, source interface, and source gateway. If more than one is specified, they are processed from most general (protocol) to most specific (gateway).

RIP doesn't support the use of preference to choose between routes of the same protocol; that is left to the protocol metrics. These protocols do not save routes that were rejected, because they have short update intervals.
