Hello. I'm not sure about correct understanding of your setup, but.. You can use this workaround: 1. Create the different static protocol with the default route: --- table other; protocol static other_default { table other; route 0.0.0.0/0 reject; } --- 2. Export this default route to ospf protocol with filter by route source. --- filter export_to_my_ospf { ...skipped... if (proto = "other_default") then { ospf_metric1 = 20; accept; } ...skipped... } protocol ospf my_ospf { ...skipped... table other; export filter export_to_my_ospf; ...skipped... } --- 3. You can prevent the installation of this default route into the kernel table with other filter. --- filter export_to_kernel { ...skipped... if ( proto = "other_default" ) then { reject; } ...skipped... } protocol kernel my_kern { table other; kernel table 100; ...skipped... export filter export_to_kernel; ...skipped... } --- 4. Note the difference between bird routing tables and system kernel tables. 29.08.2016 16:01, André Carlim пишет: Hello, first, sorry for my bad English, but I need help, I am trying to make the ospf the bird send the route default same does not being present in table main kernel, I have multiple tables, ex to the protocol ospf have the table ospf to BGP table BGP, and so on, I even have a route standard in table default kernel, I tried various forms configuration, but not got success, someone already explained that?
