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_filtering_and_multiple_RIBs
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?
