If I'm trying to delete ed interface configuration and set another ip address on it I get into the following strange situation: ifconfig displays new address but packets that are sent out on this interface to some host that is already in arp table are being sent with the old ip address in ip header! Cleaning arp entry for the host packets are being sent to resolves the problem. >How-To-Repeat: Configure ed interface, set some ip address on it. Try to ping some host in this subnet. Then delete ed interface configuration and set another ip address on it. Then try to ping the same host. Tcpdump shows that icmp packets are still being sent with the old ip. Now try to clean arp entry for the host you're trying to ping. The problem disappears, ed conf changes. The same applies to aliases on interface. >Fix: Was unable to develop anything except cleaning arp entries after reconfiguring ed interface. >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
