Hello, Ilya. I think you can implement such behaviour with setting of the krt_prefsrc attribute value inside of the export filter of a kernel protocol section. Simple example: protocol kernel k_main { scan time 10; import none; export filter { krt_prefsrc = 10.0.100.1; accept; } } Also, you can set the krt_prefsrc inside of the 'if' statement of comparing of the next hop attribute value. 2017-02-27 21:50 GMT+03:00 Илья Шипицин <chipitsine@gmail.com>:

Hello,

I run bird on centos with multiple ip addresses. what I want to achive might be easily done by running command

ip route change default via $def src N.N.N.N

where $def is variable and N.N.N.N is local address how can I achive that with bird ? any ospf route magic ? scripting after bird applies routes (I need to pick $def from that script)

thanks! Ilya Shipitsin
