Hi all,
I was notified there was a change in 1.4.0 :
This is a change in default value of 'table' for 'show route' command, now it is inferred from the protocol or export options (when used). To restore the old behavior just add 'table master' to 'show route' when no table is specified.
And I see this is explained, after reading more carefully the documentation http://bird.network.cz/?get_doc&f=bird-4.html : "show route” : Show contents of a routing table (by default of the main one or the table attached to a respective protocol), that is routes, their metrics and (in case the all switch is given) all their attributes.
May I suggest to update the documentation on gitlab ? https://gitlab.labs.nic.cz/labs/bird/wikis/Route_server_with_community_based...
Fixed.
Ondrej.

Hello,
I’m running BIRD 1.4.5 on an IXP with this setup : "Route server with community based filtering and multiple RIBs" https://gitlab.labs.nic.cz/labs/bird/wikis/Route_server_with_community_based...
I have noticed a strange behaviour of the "show route" command whenever I specify “table master” or not.
(IP/AS have been anonymised in order to follow the example above) :
root@rs2-th2:~# birdc "show route all 12.34.0.0/16 protocol R111x1" BIRD 1.4.5 ready. 12.34.0.0/16 via 10.0.0.11 on eth1 [R111x1 2015-02-16 10:43:59] * (100) [AS111i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 111 BGP.next_hop: 10.0.0.11 BGP.med: 0 BGP.local_pref: 100 BGP.community: (0,51706)
root@rs2-th2:~# birdc "show route table master all 12.34.0.0/16 protocol R111x1" BIRD 1.4.5 ready. 12.34.0.0/16 via 10.0.0.11 on eth1 [R111x1 2015-02-17 11:05:45] * (100) [AS111i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 111 BGP.next_hop: 10.0.0.11 BGP.med: 0 BGP.local_pref: 100 BGP.community: (51706,64650) (51706,64602) (0,51706)
When explicitly specifying “table master” I see communities added from filter “bgp_in_AS111”. When not specifying any table I see route from T111 (the table declared in "protocol bgp R111x1").
Actually I was expecting to have same output on both commands, as it explained in documentation : "If you want to see routes that where accepted from this router to the master routing table then type: bird> show route protocol R222x1"
Does any body also noticed this behaviour?
