I do not think so. Because of when I ping local address for an our without breaking this ping. So mac address can not die because of timeout. It dissappears from kernel routing table by some other cause. I do not know which cause

I want to use RIP

Because of I have two links to same place
router1 --- LAN1 --- router2
  |                  /
 LAN2             LAN3
  |                /
router3  ---------/


rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 00:0e:2e:db:4f:d4
        inet netmask 0xffffff00 broadcast
        inet netmask 0xffffff00 broadcast
        inet netmask 0xfffffff0 broadcast
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
I add address to rl0 by mistake. It must be on rl1 interface.
But when I added it I lose connection to my LAN. I think this behavior is bug
so I describe problem in letters earlier
