routing on a switch

if I have my core router, and a 3550 switch on my lan, I have then a wan link from this 3550 to my other office, how do I route to the layer 3 port on the switch, Do I point a route to vlan 1 on the switch from my core ?

Re: routing on a switch

If you are using static route, simply configure a static route on the core router that points to the IP address of the vlan interface on the 3550.

Hope that helps - pls do rate the post if it does.

Hi Paresh

Is this the normal pratice then ? would you mainly use layer 3 ports on my switch for wan links ? then to route to this layer 3 port I would point a route to vlan 1 on the switch from my core ?

cheers

Re: routing on a switch

Hi,

There are couple of ways you can configure the switch for WAN (routed) links.

On a layer 3 switch you can make the switchport a layer 3 (routed) port by issuing the command 'no switchport' on the physical interface and configuring all IP address & parameters on this interface. In this case, the route on your core device would point to this address as the next hop.

(or)

You can create a SVI (logical) VLAN interface and assign it the IP address. In this case, the uplink port connected to your core would be acting as a switchport (default). The route from the core would be pointing to the next hop address of the SVI (vlan) interface of this switch.

Hope that helps!

Re: routing on a switch

Hi Sundar

thanks for the reply , in your first example, are you saying to route to this layer 3 port from my core I would assign it 2 ip addresses ? 1 for my local lan and the other for the wan link ?

Re: routing on a switch

Hi there, would We normally have these layer ports plugged straight into a router, or Can we plug them into another switch ?
