I have a few NASes based on FreeBSD 7.2 and quagga 0.99.14, they all 
have same
configuration with little changes.

When I add to network a test server based on FreeBSD 8.0-STABLE
with quagga 0.99.15, other servers doesn't receive HELLO packets from him.

Counter of multicast packets on switch port constantly increasing.
What the reason of inaccessibility other servers over multicast?
