switches and mac addresses for different vlans

Hi all, if I ping a device on another subnet that is connected to my distribution switch, will my switch learn the mac address of the device in the other subnet along the trunk link? I assume it will not ?

Re: switches and mac addresses for different vlans

can anyone help here at all?

just to add, I mean the trunk link from my switch to the distribution switch, which is not a member of the vlan on the other side.

thanks

Hi

It depends upon u r toplogy .ie how u r doing u r intervlan routing usually the mac address will be learned on the trunk links.

Thanks

Re: switches and mac addresses for different vlans

the vlans are seperated by the dist switch, the vlan for that side only exsist on the trunk link needed. ie vlan 2 on one side, vlan 3 on the other,

if im right vlan 2 mac addresses should not be on trunk or switches on vlan 3, is this correct ?

No, devices in one VLAN will not learn the MAC addresses in another VLAN, since to cross VLANs they have to be routed.
