Status

For information about this field, refer to

Table 6

on page 331.

Age

The age of the route, in seconds.

Next hop

For information about this field, refer to

Table 6

on page 331.

Learned from peer

The IPv6 address of the neighbor from which this route is learned. “Local
Router” indicates that the Virtual ADX device itself learned the route.

Local pref

For information about this field, refer to

Table 6

on page 331.

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 Virtual ADX device received better routes from other sources
(such as OSPFv3 or static IPv6 routes).

D – DAMPED – This route has been dampened (by the route dampening
feature), and is currently unusable.

E – EBGP – The route was learned through a router 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 router in the same AS.

L – LOCAL – The route originated on this Virtual ADX 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
Virtual ADX, but the Virtual ADX saved updates containing the filtered
routes.

Weight

For information about this field, refer to

Table 6

on page 331.

The ASs through which routes with this set of attributes have passed. The local
AS is shown in parentheses.
