Re: switch trunking

thanks, just a follow up question. For inter VLAN, should both layer 3 switches enable routing proto (.e.g RIP, OSPF). thanks

Re: switch trunking

Hi

For intervlan routing to occur u need to create SVI's for each vlan on u r layer 3 switch.eg

int vlan 1

ip address a.b.c.d subnetmask

like this u have to create for each vlan.

there is no need to enable any dynamic routing protocol as all the networks will be directly connected.

Thanks

Re: switch trunking

In addition to Mahmood's post, on a Layer 3 switch you have to use "IP routing " to enable inter-vlan routing. For example

Conf t

Ip routing

int vlan 1

ip address x.x.x.x a.a.a.a

no shut

int vlan 2

ip address y.y.y.y a.a.a.a

HTH,
