[plug] bird routing

[William Kenworthy]

Hi all,

Ive lost patience with "frr" (routing daemon) and have decided to 
convert to using "bird" instead.  I am using ospf and its operating a 
lot better than "frr" does.

I have one road block - I want to set ospf passive-interface on one 
interface and I cant get (or prove) that is working as debugging says 
LSA's are still going out.  According to various commands, the bfd 
protocol is up, but no bfd sessions exist.  Can someone suggest where I 
am going wrong?


Relevant parts of bird.conf:

protocol bfd {
         interface "enp0s21f0u1" {
                 passive;
         };
}

...

protocol ospf v2 {
         ipv4 {
             import all;
             export where source = RTS_STATIC;
         };
         area 0 {
                 interface "enp0s21f0u1" {
                         type broadcast;
                         bfd on;
                 };
... etc.
