Hello
I have a question with regards forwarding table (bridge table) on a CHR host (GNS3/QEMU lab environment under ESXi if it makes any difference).
It is at the end of the post
Here is the list of interfaces and their MAC addresses.
Here is the bridge configuration.
VLAN21 has only one access port (where test PC is connected) and one trunk port (uplink)
VLAN configuration
It is how forwarding table looks like with highlighted unknowns..
Everything works as expected, but, those unknown lines
ether1 - with NO VID (item 0). Why this entry with NO VID appears in the table? That's I don't understand. I tried to disable MAC-Server + MAC-Server Winbox entirely. Didn't help
ether1 - with VID 1 (item 2). That's ok and there is an IP address linked to it (untagged traffic)
ether1 - with VID 21 (item 4). That's ok as port is carrying VLAN 21 tagged traffic
ether16 - with NO VID (item 1). Why this entry with NO VID appears in the table? That's I don't understand. I tried to disable MAC-Server + MAC-Server Winbox entirely. Didn't help
ether16 - with NO VID (item 5). That's ok. Test PC is connected here
Please help
