It seems that previous patch is actually not enough.
Can you try re-building port with the following patch?


2 Ondrej:
Hi, i'm a bit stuck:

For p2p interfaces, like gifX the following happens:

ifconfig gif0 inet 10.10.0.1/30 10.10.0.2

bird: (FIN) IF gre0 flags: 60000188 ip: 10.10.0.1 opposite: 10.10.0.2 
brd: 10.10.0.2
^^^^^
Kernel sets broadcast address to the peer address for given p2p 
interface even with non/32 masks.
This seems "reasonable".

if_connected() uses the following logic:
is peer? (IA_PEER) -> opposite ? OK!
not peer? -> not network addr ? not broadcast ? then OK!

Currently such interfaces are treated by nest as non-multiaccess, but 
IA_PEER is not set.

As a result, peer address is not treated as directly connected, so 
neigh_find2() returns NULL, so all LSA behind given router has their gw 
zeroed, so..

What is better: ignore kernel-supplied broadcast address or set IA_PEER 
for non-/32 masks and non-multiaccess media?
