Table 10.9: BGP4 Network Information (Continued)
Weight The value that this router associates with routes from a specific
neighbor. For example, if the router receives routes to the same
destination from two BGP4 neighbors, the router prefers the route
from the neighbor with the larger weight.
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.
• B – BEST. BGP4 has determined that this is the optimal route to
the destination.
Note: he “b” is shown in lowercase, the software was not able
to install the route in the IP route table.
• b – NOT-INSTALLED-BEST. he 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 routing
switch 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. is 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. he route was learned through BGP4.
• L – LOCAL. he route originated on this routing switch.
• M – MULTIPATH. BGP4 load sharing is enabled and this route
was selected as one of the best ones to the destination. he best
route among the multiple paths also is marked with “B”.
Note: If the “m” is shown in lowercase, the software was not able
to install the route in the IP route table.
• S – SUPPRESSED. This route was suppressed during
aggregation and thus is not advertised to neighbors.
Note: This field appears only if you enter the route option.
