Displaying route details
Here is an example of the information displayed when you use the detail option.  In this example, 
the information for one route is shown.   
Syntax: show ip bgp routes detail
Path The route’s AS path. 
NOTE: This field appears only if you do not enter the route option.
Origin code A character the display uses to indicate the route’s origin.  The origin 
code appears to the right of the AS path (Path field).  The origin codes 
are described in the command’s output.
NOTE: This field appears only if you do not enter the route option.
Status The route’s status, which can be one or more of the following:
• A – AGGREGATE. The route is an aggregate route for multiple 
networks. 
NOTE: B – BEST.  BGP4 has determined that this is the optimal route to 
the destination.
If the “b” is shown in lowercase, the software was not able to 
install the route in the IP route table.
• b – NOT-INSTALLED-BEST. The routes received from the neighbor 
are the best BGP4 routes to their destinations, but were 
nonetheless not installed in the IP route table because the device 
received better routes from other sources (such as OSPF, RIP, or 
static IP routes).
• C – CONFED_EBGP.  The route was learned from a neighbor in the 
same confederation and AS, but in a different sub-AS within the 
confederation.
• D – DAMPED.  This route has been dampened (by the route 
dampening feature), and is currently unusable.
• H – HISTORY.  Route dampening is configured for this route, and the 
route has a history of flapping and is unreachable now.  
• I – INTERNAL.  The route was learned through BGP4.
• L – LOCAL. The route originated on this device.
NOTE: M – MULTIPATH.  BGP4 load sharing is enabled and this route 
was selected as one of the best ones to the destination.  The 
best route among the multiple paths also is marked with “B”.
If the “m” is shown in lowercase, the software was not able to 
install the route in the IP route table.
NOTE: S – SUPPRESSED.  This route was suppressed during This field 
appears only if you enter the route option.
