hi every body
please consider the following scenario.
"r" stands for router
"sw1" for switch1
"sw2" for switch2
router"r" has two fast ethernet interface e1 and e2
router is connected to sw1 by e1 and to sw2 by e2.
both sw1 and sw2 have vlanA configured on their ports.
asumming router has all the proper configurations, Can a user in vlan A on sw1 communicates with a user in vlanA on sw2?
simply put can two similar vlan say vlana
communicate via router with each other?
thanks alot have a nice day
Guru Prasad is correct in that nowadays switches are often L3 capable and so take care of the inter-vlan routing but to answer your question.
Assuming the switches are not connected together and that you are using one IP subnet for vlanA then no because you will not be able to give e1 & e2 an IP address out of the same IP subnet so you could not set this up.
You could bridge between the 2 interfaces on the router which would allow you to do this but then the router is acting at layer 2 rather than layer 3.
Pls understand the basic scenario. Normally, the Router will do the L3 routing and can be used for communication between two different VLAN or Routing Protocols.
In your case,
Just Configure an up-link (trunk) between SW1 and SW2 which is higly enough for users in VLANA of both switches to communicate.
Router is not required in this case.
Do RATE if HELPS
