I'v got the example from here: https://wiki.mikrotik.com/wiki/Manual:B ... ling_setup
Switches have the same configuration:
I've simplified topology a litle bit.
Code: Select all
/interface bridge add name=bridge1 vlan-filtering=yes ether-type=0x88a8 /interface bridge port add interface=ether1 bridge=bridge1 pvid=200 add interface=ether2 bridge=bridge1 pvid=300 add interface=ether3 bridge=bridge1 /interface bridge vlan add bridge=bridge1 tagged=ether3 untagged=ether1 vlan-ids=200 add bridge=bridge1 tagged=ether3 untagged=ether2 vlan-ids=300
Let's look at the picture. Note1 is sending ICMP requests to Note2.
At the same time PacketSniffer is running on the SW1.
All is working well but the resaults:
Both switch bridges have the same Ether-type=0x88a8 and as Wiki says, packets at the
access ports(ether2) should get ehter-type 0x88a8 and VLANID=300, but
as you see that transmitted(tx) packets from ether3 port have ehter-type=8100.
Fether more! The same packets reseived (rx)at the SW2 ether3 port already have ehter-type=0x88a8.
What's going on?
