Displaying route flap dampening statistics
To display route dampening statistics for all dampened routes, enter the following command at any
level of the CLI.
Next hop For information about this field, refer to Table 192 on page 1155.
Learned from peer The IPv6 address of the neighbor from which this route is learned. “Local
router” indicates that the switch itself learned the route.
Local pref For information about this field, refer to Table 192 on page 1155.
MED The value of the advertised route’s MED attribute. If the route does not
have a metric, this field is blank.
Origin The source of the route information. The origin can be one 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.
•
b – NOT-INSTALLED-BEST – BGP4+ has determined that this is the
optimal route to the destination but did not install it in the IPv6
route table because the switch received better routes from other
sources (such as OSPFv3, RIPng, or static IPv6 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.
•
E – EBGP – The route was learned through a switch in another AS.
•
H – HISTORY – Route dampening is configured for this route, and
the route has a history of flapping and is unreachable now.
•
I – IBGP – The route was learned through a switch in the same AS.
•
L – LOCAL – The route originated on this 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 IPv6 route table.
•
S – SUPPRESSED – This route was suppressed during aggregation
and thus is not advertised to neighbors.
•
F – FILTERED – This route was filtered out by BGP4+ route policies
on the switch, but the switch saved updates containing the filtered
routes.
Weight For information about this field, refer to Table 192 on page 1155.
AS path The ASs through which routes with this set of attributes have passed.
The local AS is shown in parentheses.
