Displaying BGP4+ neighbor route-attribute entries

The route-attribute entries table lists sets of BGP4+ attributes stored in the Virtual ADX device’s
memory. Each set of attributes is unique and can be associated with one or more routes. In fact,
the Virtual ADX typically has fewer route attribute entries than routes.

For example, to display the route-attribute entries table for a BGP4+ neighbor
2001:db8:2000:4::110, enter the following command.

Syntax: show ipv6 bgp neighbor ipv6-address attribute-entries

The ipv6-address parameter displays the route attribute entries for a specified neighbor. You must
specify this address in hexadecimal using 16-bit values between colons as documented in RFC
2373.

Table 10

on page 342.

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 10

on page 342.

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:

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

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

INCOMPLETE – The routes came from an origin other than
one of the above. For example, they may have been
redistributed from OSPFv3.

When BGP4+ compares multiple routes to a destination to select
the best route, IGP is preferred over EGP and both are preferred
over INCOMPLETE.

Weight

For information about this field, refer to

Table 10

on page 342.

AS-PATH

The AS-path information for the route.

Adj RIB out count

The number of routes in the Virtual ADX device’s current BGP4+
Routing Information Base (Adj-RIB-Out) for a specified neighbor.

Admin distance

The administrative distance of the route.
