Displaying BGP4+ information
This display shows the following information.
TABLE 106 Detailed filtered-out BGP4+ route information
This field... Displays...
Status codes A list of the characters the display uses to indicate the route’s status. The
Status field display an “F” for each filtered route.
Prefix For information about this field, refer to Table 105 on page 542.
Status For information about this field, refer to Table 105 on page 542.
Age The age of the route, in seconds.
Next hop For information about this field, refer to Table 105 on page 542.
Learned from peer The IPv6 address of the neighbor from which this route is learned. “Local
Router” indicates that the device itself learned the route.
Local pref For information about this field, refer to Table 105 on page 542.
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 device 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 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 in the same AS.
•
L – LOCAL – The route originated on this device.
•
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
device, but the saved updates containing the filtered routes.
Weight For information about this field, refer to Table 105 on page 542.
AS path The ASs through which routes with this set of attributes have passed. The local
AS is shown in parentheses.
