9 | +Bird, like any other routing daemon, inserts routes into the kernel. If you don't specify a source address on the kernel routes, then the kernel will choose for you (and will often choose an address in a transfer subnet, which is not what you want). |
|
10 | + |
|
11 | +To specify the source address, you use the `krt_prefsrc` attribute, for instance in the export filter of the kernel protocol: |
|
12 | + |
|
13 | + protocol kernel { |
|
14 | + export filter { |
