In this post I will walk you through the steps of creating Virtual Router and then assign interfaces to the router.
Network –> Virtual Routers
Then select the virtual router “IT_VR”
In this post I will configure static rout; I will route all traffic to ISP (Default route); assuming that the ISP router IP address is 220.127.116.11
Static Routes –> Add
Type name, select the Interface (ethernet1/2) and Next Hop keep the default Metric 10
Optional I have added additional static route on LAN Interface assuming internal router IP is 10.128.1.100
You will need to click “Commit” then the changes take effect
