Re: BGPD and source interface

route [-T rtable] sourceaddr [-inet|-inet6] [address]
route [-T rtable] sourceaddr [-inet|-inet6] -ifp interface
Set the preferred source address. If address is the word
"default", 0.0.0.0 or ::, source address will be chosen by
the kernel for the matching address family. When address is
omitted, preferred source address is printed if set. If -ifp
is used, source will use IP assigned to interface. The
preferred source will not be used when:

o destination is on-link
o source address is assigned to a disabled interface

This is best used as a !route command in a hostname.* file.
