Vlans and Routing

Hi,

I had a layer 3 switch and like to divide into 9 different vlans, There will be a admin vlan than will be able to broadcast information to the other 8 other vlans. Is this possible? Thanks.

Hi,

I am bit confused with the term broadcast is used here . however if you mean to say your 9th vlan should be able to talk to rest of  the 8 vlans then answer would be Yes.

You should have L3 interfaces created for these vlans. All those will be connected routes on layer 3 switch .Should have any problem communicating with each other.

Thanks

Thanks ajay. So if my admin vlan is to send the same message to all the 8 vlans at the same time, I believe that I have to route the message 8 times to all the different vlans.

Communication between vlan should not be a problem . As i said you should have Vlan interfaces created for all these 9 vlan you mentioned. When you do show ip route you will see all as connected routes.

hi,

if you only want to send "normal" traffic between the vlans then ajay is right. the problem will be sending broadcasts.

broadcasts are never routed unless its a directed broadcast, but this broadcast is just intended for a specific broadcast domain and thus wouldnt be routed to all the vlans(broadast domains).
