Displaying BGP4 information
Syntax: show ip bgp routes summary
This display shows the following information.
Displaying the BGP4 route table
BGP4 uses filters that you define as well as the algorithm described in “How BGP4 selects a path
for a route (BGP best path selection algorithm)” on page 5 to determine the preferred route to a
destination. BGP4 sends only the preferred route to the IP table. To view all the learned BGP4
routes, you can display the BGP4 table.
To view the BGP4 route table, enter the following command.
TABLE 10 BGP4 summary route information
This field... Displays...
Total number of BGP4 routes (NLRIs)
Installed Number of BGP4 routes the device has installed in the BGP4 route table.
Distinct BGP4 destination networks Number of destination networks the installed routes represent. The
BGP4 route table can have multiple routes to the same network.
Filtered BGP4 routes for soft reconfig 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 103.
Routes originated by this device Number of routes in the BGP4 route table that this device originated.
Routes selected as BEST routes 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 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) Number of routes in the BGP4 route table whose destinations are
unreachable because the next-hop is unreachable.
IBGP routes selected as best routes Number of “best” routes in the BGP4 route table that are IBGP routes.
EBGP routes selected as best routes Number of “best” routes in the BGP4 route table that are EBGP routes.
