vlan, trunk and networks

[erdosain99]

Hi.

I have this diagram...

I want to configure the cisco 2901 with ip (10.0.0.2), and passthroug vlan 10, and 100.

Network 192.168.2.0 with access to "internet"-------Router 10.0.0.1.

All other router 1, 2 and 3 access "internet" also router 10.0.0.1.

Can give me a hand?

See if the configuration guides and/or command reference manual describe bridging.

Ok, but i have network 192.168.2.0/24, that uses the cisco router 2901 like router. Cisco router is the "access to internet (wan)" with NAT to that net... so... is possible??

I mean, all the others, go to router 10.0.0.1 directly, but 192.168.2.0/24 go to router cisco 2901 (10.0.0.2) and reach router 10.0.0.1 .

Thanks!

As I understood from your question.
The scenario is: You have a router connected to the Internet and another routers not connected to the Internet, and you want to allow the subnet 192.168.2.0/24 to access the Internet

So:
You need to put the network 192.168.2.0/24 in a separate VLAN such as VLAN 10
On cisco 2901 router (10.0.0.2) configure SVI with secondary IP address for VLAN 10 and make it the default gateway for the network 192.168.2.0/24
Then you can use NAT to allow the Internet access for this subnet
Don't forget to only allow vlan 10 to pass on the trunk toward the 2901 router
In the router 10.0.0.1 create SVI to to be default gateway for the rest of your network you can create a separate SVI for each VLAN

I hope that I could answer your question.
