It appears that BIRD does not fully appreciate RFC3021 style addresses on Ubuntu 15.04, when I start BIRD:
syslog:Nov 10 15:25:15 eunetworks-2 bird: KIF: Invalid broadcast address 255.255.255.255 for em1 syslog:Nov 10 15:25:15 eunetworks-2 bird: KIF: Invalid broadcast address 255.255.255.255 for p2p2.1003
BIRD works with RFC 3021 style addresses without problems, it is just confused by the fact that directed broadcast address for the iface is configured to 255.255.255.255, which is address reserved for link-local broadcast.
BIRD should work without problems on these interfaces (unless you use broadcast like in RIPv1), it is just warning.
Acknowledged. I see no issues other then the warnings.
Should I configure the Linux side of things differently or is this something that needs resolving in BIRD itself?
IMHO reasonable setting would be to not set directed broadcast address on such interfaces. Link-local broadcast address works for any interfaces and need not be configured.
The interface is brought up by ifup(8) and friends, this is the input: # em1: Core: to eunetworks-1 auto em1 iface em1 inet static address 94.142.247.237 netmask 255.255.255.254 gateway 94.142.247.236 Any recommendations on what I can change to prevent the warning? Kind regards, Job
