Re: [Openbsd-misc] vlan setup, arp issue
I think your routers all know the ipadresses and the macadresses.
When your host sends a arp request, all reply, it add's the first
reply, and then it gets another couple of reply's.
it informs you of that in your logfiles.
Static arps can indeed resolve those issues since it knows where
to find the adresses...
It's also an security advantage since no one can spoof the macadresses
of your hosts. (Well no know things today:))

Onderwerp: [Openbsd-misc] vlan setup, arp issue
Running 3.4 and trying to setup a VLAN trunk on fxp0.
inet 10.110.26.222 255.255.252.0 NONE
inet 188.8.131.52 255.255.255.192 NONE vlan 2 vlandev fxp0
Host is connected to a Cisco 6509, native VLAN2. Default router is
184.108.40.206 (HSRP VIP, the routers are .2 and .3).
I get the following errors when trying to connect to anything:
Feb 20 06:07:06 caf3 /bsd: arp: attempt to add entry for 220.127.116.11 on
vlan2 by 00:d0:00:ec:b7:fc on fxp0
Feb 20 06:07:17 caf3 /bsd: arp: attempt to add entry for 18.104.22.168 on
vlan2 by 00:00:0c:07:ac:00 on fxp0
Feb 20 06:13:54 caf3 /bsd: arp: attempt to add entry for 22.214.171.124 on
vlan2 by 00:d0:00:ea:17:fc on fxp0
I can "fix" this by adding static arp entries but this isn't ideal. Should
fxp0's address be the same as vlan2 (since it's the native vlan anyways) ?
Or do I have some sort of config error.
