Hi.
I'm a bit confused. I have the following configuration:
# dladm show-vnic
LINK OVER SPEED MACADDRESS MACADDRTYPE VID
pri0 e1000g0 1000 2:8:20:d8:19:49 random 300
oivm0 e1000g0 1000 2:8:20:3:e:d5 random 218
Virtual machine (VirtualBox) is connected in bridged mode to oivm0
interface.
Inside VM I configured address frrom 218 vlan (10.132.100.0/24) and
trying to ping router (without success, don't see arp replies).
I see the following, while listening on e1000g0 with tcpdump:
# tcpdump -i e1000g0 'vlan 218'
dropped privs to nobody
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on e1000g0, link-type EN10MB (Ethernet), capture size 262144 bytes
11:25:40.310953 ARP, Request who-has 10.132.100.1 (Broadcast) tell
oi-vm.cc.rsu.ru, length 46
11:25:40.311595 ARP, Reply 10.132.100.1 is-at 00:1e:4a:b4:ea:c0 (oui
Unknown), length 46
11:25:40.810853 ARP, Request who-has 10.132.100.1 (Broadcast) tell
oi-vm.cc.rsu.ru, length 46
11:25:40.811634 ARP, Reply 10.132.100.1 is-at 00:1e:4a:b4:ea:c0 (oui
Unknown), length 46
Now listening on oivm0:
# tcpdump -i oivm0
...
11:28:33.504326 ARP, Request who-has 10.132.100.1 (Broadcast) tell
oi-vm.cc.rsu.ru, length 46
...
But no arp replies from 10.132.100.1 ( 00:1e:4a:b4:ea:c0 )...
Router sees VM's mac address:
# sh mac-address-table int Gi3/8
Legend: * - primary entry
age - seconds since last seen
n/a - not available
vlan mac address type learn age ports
------+----------------+--------+-----+----------+--------------------------
* 218 0800.27d7.8ad6 dynamic Yes 0 Gi3/8
* 300 0208.20d8.1949 dynamic Yes 0 Gi3/8
If I assign 10.132.100.254/24 address to oivm0, I can ping the router
from physical host.
Now the question - what am I doing wrong?????
