hi every body!
Let say we have an access switch sw1 which is connected to distribution switches sw2 and sw3 via port f0/2 and f0/3 respectively.
swi port f0/2 is root port while f0/3 is blocked port. Sw1 is using uplink feature
sw1 has following mac table
mac3 f0/4 ( host connected to sw1 f0/4)
when the f0/2 link goes down, sw1 will send dummay frames ,using mac addresses as sourse addreses. My point is even for those hosts such as mac1 and mac2 which are reachable via f0/2, which are not directly connected to sw1, will sw1 send dummy frames? or does it(sw1) send dummy frames for the hosts which are directly connected to sw1?
thanks a lot!
