Hey Maria, thanks for the quick reply. I have seen that 1.6.5 is included in Debian testing and will pull it from there. Are there any plans to work with Debian or other distributions to include 2.0.4 in the packaging system? Best, Nico Maria Matejka <jan.matejka@nic.cz> writes:

Hello! This is a bug that was fixed in commit da65a3d898fde0ce567782d86919a66e29916ed7

Please upgrade to v1.6.5 (or better to v2.0.4).

Hello,

I am using bird 1.6.3 (from debian) and if I use the following filter, bird "crashes" when issueing the "conf" command:

Apr 19 21:29:53 router1 bird: Reconfiguring Apr 19 21:29:53 router1 bird: Unknown instruction 8574 in same (~)

filter:

filter to_netstream { if(is_inside_ungleich()) then { if(net !~ net_prefer_netstream) then { bgp_path.prepend(myas); bgp_path.prepend(myas); bgp_path.prepend(myas); print "Policy: changed bgppath ", net, " ", bgp_path, " for init7"; } accept; }

reject; }

If I change the filter to

filter to_netstream { if(is_inside_ungleich()) then { # if(net !~ net_prefer_netstream) then { # bgp_path.prepend(myas); # bgp_path.prepend(myas); # bgp_path.prepend(myas); # print "Policy: changed bgppath ", net, " ", bgp_path, " for init7"; # } accept; }

reject; }

this problem does not occur.

Is this a bug in bird or am I using it "incorrectly"?

Best,

Nico
