10.11.16.14 is local address
tcpdump on the interface with this address shows nothing

I do not think so. Because of when I ping local address 10.11.16.14 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

router3 ---------/
router1: 10.0.16.1/24, 10.10.16.8/24

I add 10.10.16.3 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
