For example, I got these errors of "bridge_mdb_port_down.sh": $ sudo ./bridge_mdb_port_down.sh TEST: MDB add/del entry to port with state down [ OK ] Error: ipv4: Address not found. Error: ipv6: address not found. Error: ipv4: Address not found. Error: ipv6: address not found. These errors occur when using h1_destroy() and h2_destroy() to delete the addresses of h1 (192.0.2.1, 2001:db8:1::1) and h2 (192.0.2.2, 2001:db8:1::2): h1_destroy() { simple_if_fini $h1 192.0.2.1/24 2001:db8:1::1/64 } h2_destroy() { simple_if_fini $h2 192.0.2.2/24 2001:db8:1::2/64 } It seems that when invoking h1_destroy() and h2_destroy(), both h1 and h2 no longer have IP addresses. I added "ifconfig" to show the addresses of h1 and h2 before invoking h1_destroy() and h2_destroy() like this: ''' @@ -105,7 +105,9 @@ cleanup() pre_cleanup switch_destroy + ifconfig $h1 h1_destroy + ifconfig $h2 h2_destroy vrf_cleanup ''' And got these messages: TEST: MDB add/del entry to port with state down [ OK ] veth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 ether f2:ca:02:ee:05:19 txqueuelen 1000 (Ethernet) RX packets 149 bytes 17355 (17.3 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 81 bytes 9165 (9.1 KB) TX errors 0 dropped 12 overruns 0 carrier 0 collisions 0 Error: ipv4: Address not found.
