CISCO 871W Router

[Ahmed Abdulla Mohammed Sallam]

Good Afternoon Colleagues

 hope you are doing well . One of our clients has CISCO 871W router . As you know , The LAN interface of this router is Fast Ethernet 4-ports managed switch . I have the below inquiries:

• Can i have more than one vlan on this LAN interface (VLAN 1 , Vlan 10 , Vlan 20) ?
• Can i have Interface Vlan 1 , Interface Vlan 10 , Interface Vlan 20 ?
• Can i apply the command "ip nat inside" to interface Vlan 1 , Interface Vlan 10 , Interface Vlan 20 ?

Best Regards

I do not have experience with this particular model, but based on my experience with other Cisco routers I believe that yes you can more than one vlan, that each vlan can have its own vlan interface with its own IP address, and that you could apply ip nat inside to each of the vlan interfaces.

It's been years since I've had hands-on with an 8xx ISR, but I believe the answer to all your questions is yes.

The 8xx series, I also recall, use a few different commands working with their VLANs than do other ISRs with L2 modules.
