I have Cisco 871 router witch has 1 WAN interface and 4-port 10/100-Mbps managed switch.
My question is: Can I connect this router with 2 ISP's? One of the ISP's I can connect with the WAN port, but can I connect the other ISP to one of the 4-port managed switch and to separate it in other VLAN.
My Idea is when one of the ISP's fails the LAN PC's to go over the other ISP.
What is in general the difference between WAN and LAN interface on Cisco 800 series.
Thanks in advance!
You can connect the second isp link onto one of the switch ports and configure a VLAN(SVI) attached to it.
But the catch here is with the Base Image u have limitations in configuring the VLANs (SVI Interfaces).
You can overcome the same by upgrading the base image to Advanced IP services IOS image to have support for more numbers of VLANs(SVIs).
