Hi, In Section 3.3 - Protocol options in the User's Guide, I noticed this: import all | none | filter name | filter { filter commands } | where filter expression Specify a filter to be used for filtering routes coming from the PROTOCOL to the ROUTING TABLE. all is shorthand for where true and none is shorthand for where false. Default: all. export filter This is similar to the import keyword, except that it works in the direction from the ROUTING TABLE to the PROTOCOL. Default: none. I'm a little confused what the capitalized words "PROTOCOL" and "ROUTING TABLE" exactly mean. For exmaple, if I wrote "import all;" in the OSPF protocol, it will import all the routes that OSPF protocol detects to the BIRD's routing table, right? But when I wrote "export all;" in the OSPF protocol, the routes will be exported from the BIRD's routing table to where? Also, if I wrote "import all;" and "export all;" in the Kernel protocol, the routes will be imported and exported from where to where? Is it importing from the kernel table to the BIRD's routing table and exporting routes from the BIRD's routing table to the kernel table? Thanks.
