Displaying BGP4+ information

Displaying BGP4+ neighbor route-attribute entries
The route-attribute entries table lists sets of BGP4+ attributes stored in the switch’s memory. Each
set of attributes is unique and can be associated with one or more routes. In fact, the switch
typically has fewer route attribute entries than routes.
For example, to display the route-attribute entries table for a BGP4+ neighbor 2000:4::110, enter
the following command.
TABLE 211 Detailed route information advertised to a BGP4+ neighbor
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 210 on page 1258.
Status codes For information about this field, refer to Table 210 on page 1258.
Prefix For information about this field, refer to Table 210 on page 1258.
Status For information about this field, refer to Table 210 on page 1258.
Age The age of the advertised route, in seconds.
Next Hop For information about this field, refer to Table 210 on page 1258.
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 210 on page 1258.
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 or RIPng.
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 210 on page 1258.
AS-PATH The AS-path information for the route.
Adj RIB out count The number of routes in the switch’s current BGP4+ Routing Information
Base (Adj-RIB-Out) for a specified neighbor.
Admin distance The administrative distance of the route.
