To display the BGP4 routes are the “best” routes to their destinations but are not installed in the Layer 3 Switch’s
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”. See Table 21.10 on page 21-91 for a
description.
Syntax: show ip bgp routes not-installed-best
For information about the fields in this display, see Table 21.10 on page 21-91. The fields in this display also
appear in the show ip bgp display.
NOTE: To display the routes that the Layer 3 Switch has selected as the best routes and installed in the IP route
table, display the IP route table using the show ip route command.
Displaying BGP4 Routes Whose Destinations Are Unreachable
To display BGP4 routes whose destinations are unreachable using any of the BGP4 paths in the BGP4 route
table, enter a command such as the following at any level of the CLI:
Syntax: show ip bgp routes unreachable
For information about the fields in this display, see Table 21.10 on page 21-91. The fields in this display also
appear in the show ip bgp display.
