Displaying those best BGP4 routes that are nonetheless not in the IP route table
When the Layer 3 Switch has multiple routes to a destination from different sources (such as
BGP4, OSPF, RIP, or static routes), the Layer 3 Switch 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 are the “best” routes to their destinations but are not installed in the
Layer 3 Switch IP route table, enter a command such as the following at any level of the CLI.
Each of the displayed routes is a valid path to its destination, but the Layer 3 Switch received
another path from a different source (such as OSPF, RIP, or a static route) that has a lower
administrative distance. The Layer 3 Switch always selects the path with the lowest administrative
distance to install in the IP route table.
Notice that the route status in this example is the new status, “b”. Refer to Table 131 on page 838
for a description.

route table, display the IP route table using the show ip route command.
Displaying BGP4 routes whose destinations are unreachable

BGP4 route table, enter a command such as the following at any level of the CLI.
