Hi, A virtual router is a routing-instance type. It will create a new routing-table You will have to configure interfaces and addresses under the "main" instance After that you will "call" interface (ie fe-0/0/0.0) under the routing-instance statement. Here is an example that run BGP set interface fe-0/0/0 unit 0 family inet address 192.168.0.2/30 set routing-instances TEST instance-type virtual-router set routing-instances TEST interface fe-0/0/0.0 set routing-instances TEST protocols bgp local-as 65000 set routing-instances TEST protocols bgp group EXT type external set routing-instances TEST protocols bgp group EXT neighbor 192.168.0.1 peer-as 65001 Hope this will help you
