It is strange that you have such different source IP addresses. What is your IP range on vl-foo? What is reported by birdc commands 'show interfaces' and 'show ospf interface' ? Generally OSPFv2 interfaces are associated with one IP range, so alien packets are ignored.
I have 2 addresses on the interface in this case. vl-foo up (index=22 master=foo) MultiAccess Broadcast Multicast AdminUp LinkUp MTU=1500 100.63.16.4/21 (Preferred, scope univ) 192.168.1.5/24 (scope site) fe80::4d8:7ff:fe73:68b6/64 (Preferred, scope link) The idea is that the primary range, 100.x.x.x, is used for OSPF between nodes on the VLAN, and the secondary address is to emulate a legacy device, where the same address is needed on multiple VLANs. The secondary address isn't actually involved here, but I don't see a way in the documentation to limit it to only sending out with the primary address. -- James Oakley james.oakley@multapplied.net
