Syntax: show ip bgp routes summary
This display shows the following information.
Displaying the BGP4 route table
BGP4 uses filters you define as well as the algorithm described in “How BGP4 selects a path for a
route” on page 816 to determine the preferred route to a destination. BGP4 sends only the
preferred route to the router’s IP table. However, if you want to view all the routes BGP4 knows
about, you can display the BGP4 table.
To view the BGP4 route table, enter the following command.
TABLE 140 BGP4 summary route information
This field... Displays...
Total number of BGP routes (NLRIs)
Installed The number of BGP4 routes the device has installed in the BGP4 route
table.
Distinct BGP destination networks The number of destination networks the installed routes represent. The
BGP4 route table can have multiple routes to the same network.
Filtered BGP routes for soft reconfig The number of route updates received from soft-reconfigured neighbors
or peer groups that have been filtered out but retained. For information
about soft reconfiguration, refer to
“Using soft reconfiguration” on
page 893.
Routes originated by this router The number of routes in the BGP4 route table that this device originated.
Routes selected as BEST routes The number of routes in the BGP4 route table that this device has
selected as the best routes to the destinations.
BEST routes not installed in IP
forwarding table The number of BGP4 routes that are the best BGP4 routes to their
destinations but were not installed in the IP route table because the
device received better routes from other sources (such as OSPF, RIP, or
static IP routes).
Unreachable routes (no IGP route for
NEXTHOP) The number of routes in the BGP4 route table whose destinations are
unreachable because the next hop is unreachable.
IBGP routes selected as best routes The number of “best” routes in the BGP4 route table that are IBGP
routes.
EBGP routes selected as best routes The number of “best” routes in the BGP4 route table that are EBGP
routes.
