Hosts MAC address Replication between Switches
Hosts MAC address Replication between Switches
I would like to know for instance if I check the Mac address table of all 4 Switches in the topology above , may I find the mac address of PC1 and PC2, or do I need to generate traffic , ex: ping from PC to PC ? OR the mac address of both PCs can exist only on the Switches they are directly connected to ?
Thank you

NO,
If your want to access an IP address there are two options:
1) it falls within one of the connected networks (directly attached) - Query address is IP address mentioned
2) it Doesn't then a route lookup is done where the netmask decrement until a match is found.
(The ulitmate match is netmask 0 (implying ip address of network 0.0.0.0) aka the default route.
On match query address is set to the gateway address found.
Then the network technology is determined: Point-Point (tunnel) or Broadcast network.. (Ethernet, tokenbus, tokenring, radio).
In the PtP case the packet is handed to the transmitter... (what goes in one end will pop up on the other end, regardless).
In the case of Broadcast Address Resolution is needed:
Then first the ARP table is checked if the entry is KNOWN.. (Either static, or recent query).
If unknown then an ARP query is done to get the MAC address of the Query address.
The MAC address found is used by the transmitter as the target address for then network frame.
Arp table can be checked, manipulated with the arp utility.

EE for some reason gives just the option to select Best Solution. You cannot assign Assisted Solutions
Maybe request help from a moderator. AFAIK after selecting the best optional should be selectable (before accepting) ..
Also assignment of points should selectable somewhere.

Thank you Guys!

By just plugging PC1 and PC2 to their respective Switches will cause ARP request to go to all other switches ?
