Re: enc0 without MULTICAST flag

Thanks a lot,

I'll try it tomorrow. Unfortunately I won't attend EuroBSDCon,

anyway, thanks a lot for the invite.

Use sec(4) for this. Don't use enc for anything except inspection. If you are at EuroBSDCon this weekend, come to my talk as I'll be diving into this exact subject.

Cheers,

Jason.

I configured a site-to-site vpn with ike2,

it works for unicast traffic.

I need to enable ospf on the 2 hosts via enc0, but

ifconfig enc0 shows:

enc0: flags=41<UP,RUNNING>
        index 2 priority 0 llprio 3
        groups: enc
        status: active
        inet .......

So, ospfd shows, in /var/log/daemon:

  ospfd[53563]: if_join_group: error IP_ADD_MEMBERSHIP, interface enc0 address 224.0.0.5: Can't assign requested address

How can I set the flag MULTICAST on enc0?

man ifconfig doesn't say how to to it.
