HI imran.

Fisrt verify weather all the trunk configurations are working properly between the switches.

And on 3550 u have to create SVI's for each vlan u have defined,

For eg

interface vlan

ip address this will be the gateway for u r clients.

and may this link will help u .

Hi Imran,

In addition to above post remember to enable "ip routing" command on global config mode because it is disable on 3550 switch and till the time it is disable intervlan routing or normal routing will not work.

Once you enable "ip routing" you will be able to see all your vlans (logical interfaces are necessary) in your routing table as directly connected and intervlan rotuting will start working.

Dear imran,

Inter Routin routing used with MLS switches to route between different vlans, the interface VLAN ip address must be belong to the same subnet that the hosts on the vlan area using which then will be used as GW address for all vlan members.

CA3550(config)#vlan 600

CA3550(config-vlan)#name blabla

CA3550(config-if)#interface f0/1

CA3550(config-if)#switchport

CA3550(config-if)#switchport mode access

CA3550(config-if)#switchport access vlan 600

CA3550(config-if)#exit

CA3550(config-if)#interface vlan600

CA3550(config-if)#ip address 10.0.0.1 255.255.255.0

hi imran,

here you need to creat the multiple svi...like this

config)#interface vlan XXX

config-if)# ip address 10.1.x.x 255.x.x.x

config-if)# no shut

config)#interface vlan yyy

config-if)# ip address 10.2.x.x 255.x.x.x

config-if)# no shut

like this on switch 33550

hope this helps you

rate this post if it helps
