When the Extreme device has multiple routes to a destination, the device selects the route with the lowest administrative distance as the best route, and installs that route in the IP route table.
To display the BGP4 routes that are the “best” routes to their destinations but are not installed in the device‘s IP route table, enter a command such as the following at any level of the CLI.
device(config-bgp-router)# show ip bgp vpnv4 routes not-installed-best
Searching for matching routes, use ^C to quit...

Each of the displayed routes is a valid path to its destination, but the device received another path from a different source that has a lower administrative distance. The device always selects the path with the lowest administrative distance to install in the IP route table.
Syntax: show ip bgp vpnv4 routes not-installed-best
For information about the fields in this display, see the Displaying the VPNv4 route table task.
Note
To display the routes that the Extreme device has selected as the best routes and installed in the IP route table, display the IP route table using the show ip route command.
