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.
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
: 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 Layer
3 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. 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 Layer 3 Switch.
•
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”.
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.
