Hi,

VLAN interfaces are your best bet, unless you want to invest in a router just to do inter-vlan routing.

You can do something like the following:

interface vlan10

ip address x.x.x.1 255.255.255.0

!

interface vlan20

ip address y.y.y.1 255.255.255.0

Hi ,

Thanks for the Ans

Yes I ahve given the Vlan Ips

,,

ip address x.x.x.3 255.255.255.0

!

interface vlan20

ip address y.y.y.30 255.255.255.0

X.1 and Y.1 are my gateways diiferent gatway;s,

Should i used static route for this ????

and

IP route X.X.X.X 255.255.255.224 ??? on gateway ip ?????

Same for Y.Y.Y.Y ????

Thanks

I do not see any need for static routes. If the gateway address is in the same subnet as the VLAN interface address then the switch should be able to ARP and find the MAC address of the gateway and get to it. If the gateway is not reachable by ARP then how can it be in the same subnet?

if you've created both VLAN intefaces on your switch and have them "no shutdown" then you should not need any static routes to communicate between those two vlans.

you'll only need additional routes (static or dynamic) in order to allow those two VLAN interfaces/subnets to communicate with other subnets outside that switch.

Hi
