3550EMI Routing and PIX

[cashford]

I am new to the 3550 and to L3 routing on the switch. I need to create 3 vlans(no problem) with no routing between the vlans, then route all the Internet traffic from each vlan out one port to a PIX. The PIX config is no problem.

vlan100 \

------------ \

vlan101 \ ----> PIX------>2600----->Internet

------------ /

vlan102 /

I have not been able to find many configuration examples for L3 routing on the 3550's.

Can someone please point me to where I can find resources, examples and sample configs, using the 3550 and L3 routing.

Thanks

Hi

Here a link to how you can configure your C3550.

http://www.cisco.com/en/US/products/hw/switches/ps646/products_configuration_guide_chapter09186a00800c6f5b.html

You also have to installe an ios which supports the routing. On the linked page you will find it right on top.

I would just make the port to the pix a L3 port with the command "no switchport". After that you can define a IP Address for the port. And finaly you have to configure a static route which points to the pix "ip route 0.0.0.0 0.0.0.0 ".

Hope that helps

Thanks, that doc doesn't explain routing or show examples that give me the full picture.

When I define my three vlans, do I create an SVI to get an ip address assigned to each vlan, to allow routing to the L3 port(no switchport)?

Hi

I'm not quite sure if it is on the c3550 the same, but probably you can define the follwing:

interface vlan

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

So if you can define that....that's all.

For configuration you probably best check the configuration guides.
