Displaying BGP4+ information

TABLE 2 Detailed BGP4+ route information

This field... Displays...

Number of BGP4+ Routes advertised

to specified neighbor (appears only

in display for all routes)

For information about this field, refer to Table 1 on page 321.

Status codes For information about this field, refer to Table 1 on page 321.

Prefix For information about this field, refer to Table 1 on page 321.

Status For information about this field, refer to Table 1 on page 321.

Age The age of the advertised route, in seconds.

Next Hop For information about this field, refer to Table 1 on page 321.

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 1 on page 321.

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.

• EGP – The routes with this set of attributes came to BGP4+ through

EGP.

• H – HISTORY. Route dampening is configured for this route, and the

route has a history of flapping and is unreachable now.

• IGP – The routes with this set of attributes came to BGP4+ through

IGP.

• L – LOCAL. The route originated on this Virtual ADX.

• 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.

Weight For information about this field, refer to Table 1 on page 321.

AS-PATH For information about this field, refer to Table 1 on page 321.

Adj_RIB_out count The number of neighbors to which the route has been or will be

advertised. This is the number of times the route has been selected as

the best route and placed in the Adj-RIB-Out (outbound queue) for a

BGP4+ neighbor.

Admin Distance The administrative distance of the route.
