Filter being ignored.

[Steve (Telsat Broadband)]

Hi John,

 

Initially, I thought this was working, but apparently not, the routes are
still making it into the Cisco routing table:

 

protocol ospf {

        import all;

        export filter {

                ospf_metric1 = 1000;

                if ( net ~ [ 192.168.0.0/16+ ] ) then reject;

                if ( source = RTS_STATIC ) then accept; else reject;

        };

 

O     192.168.38.0/24 

           [110/1001] via xxx.xxx.xxx.xxx, 00:00:15, GigabitEthernet0/1

O     192.168.39.0/24 

           [110/1001] via xxx.xxx.xxx.xxx, 00:00:15, GigabitEthernet0/1

 

 

Cheers.

Steve.

I think you want to use ~ instead of =:

 

protocol ospf {

        import all;

        export filter {

                ospf_metric1 = 1000;

                if ( net ~ [ 192.168.0.0/16+ <http://192.168.0.0/16+>  ] )
then reject;

                if ( source = RTS_STATIC ) then accept; else reject;

        };

Hi All,

 

I've configured the following 'export' filter in my OSPF protocol:

 

 

protocol ospf {

        import all;

        export filter {

                ospf_metric1 = 1000;

                if ( net = [ 192.168.0.0/16+ <http://192.168.0.0/16+>  ] )
then reject;

                if ( source = RTS_STATIC ) then accept; else reject;

        };

 

Yet on my router, I'm still seeing the route coming in via OSPF:

 

O     192.168.38.0/24 <http://192.168.38.0/24>  

           [110/1001] via xxx.xxx.xxx.xxx, 00:00:05, GigabitEthernet0/1

O     192.168.39.0/24 <http://192.168.39.0/24>  

           [110/1001] via xxx.xxx.xxx.xxx, 00:00:05, GigabitEthernet0/1

 

Is there something I'm missing?  How can I get these network's excluded?

 

Cheers.

Steve.
