Re: Extending existing LAN

Hi,

You need to configure trunk between the 2960 and the one 3550 and one trunk between the two other.

Switch(config)# interface fastethernet0/4

Switch(config-if)# switchport mode trunk

Switch(config-if)# switchport trunk encapsulation dot1q

If your 3550 has 2 gig-links then you might concider configuring etherchannel ?
