Displaying the best routes that were nonetheless not installed in the IP route table
To display the BGP4 routes received from a specific neighbor that 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.
PowerConnect#show ip bgp neighbors 192.168.4.211 routes not-installed-best
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.
Syntax: show ip bgp neighbors <ip-addr> routes not-installed-best
For information about the fields in this display, refer to Table 189 on page 1083. The fields in this
display also appear in the show ip bgp display.
Displaying the 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.
PowerConnect#show ip bgp neighbors 192.168.4.211 routes unreachable
Syntax: show ip bgp neighbors <ip-addr> routes unreachable
For information about the fields in this display, refer to Table 189 on page 1083. The fields in this
display also appear in the show ip bgp display.
Displaying the Adj-RIB-Out for a neighbor
To display the Layer 3 Switch current BGP4 Routing Information Base (Adj-RIB-Out) for a specific
neighbor and a specific destination network, enter a command such as the following at any level of
the CLI.
The Adj-RIB-Out contains the routes that the Layer 3 Switch either has most recently sent to the
neighbor or is about to send to the neighbor.
Syntax: show ip bgp neighbors <ip-addr> rib-out-routes [ <ip-addr> / <prefix> ]
For information about the fields in this display, refer to Table 189 on page 1083. The fields in this
display also appear in the show ip bgp display.
