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’s IP route table, enter a command such as the following at any level of the CLI:
FESX424 Router(config-bgp-router)# show ip bgp neighbor 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 neighbor <ip-addr> 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.
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:
FESX424 Router(config-bgp-router)# show ip bgp neighbor 192.168.4.211 routes
unreachable
Syntax:
show ip bgp neighbor <ip-addr> 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.
Displaying the Adj-RIB-Out for a Neighbor
To display the Layer 3 Switch’s 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 neighbor <ip-addr> rib-out-routes [<ip-addr>/<prefix>]
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.
Displaying Peer Group Information
You can display configuration information for peer groups.
To display peer-group information, enter a command such as the following at the Privileged EXEC level of the CLI:
FESX424 Router(config-bgp-router)# show ip bgp neighbor 192.168.4.211 rib-out-
routes 192.168.1.0/24
