Displaying BGP4+ information

Displaying BGP4+ 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.
To display the IPv6 route-attribute entries table, enter the following command:
NOTE
Portions of this display are truncated for brevity. The purpose of this display is to show all possible
fields that might display rather than to show complete output.
TABLE 189 BGP4+ route information
This field... Displays...
Total number of BGP Routes (appears
in display of all BGP routes only) The number of routes known by the switch.
Number of BGP Routes matching
display condition (appears in display
that matches specified and longer
prefixes) The number of routes that matched the display parameters you entered.
This is the number of routes displayed by the command.
Status codes A list of the characters the display uses to indicate the route’s status.
The status code appears in the left column of the display, to the left of
each route. The status codes are described in the command’s output.
Origin codes A character the display uses to indicate the route’s origin. The origin
code appears to the right of the AS path (Path field). The origin codes are
described in the command’s output.
Network The network prefix and prefix length.
Next Hop The next-hop switch for reaching the network from the switch.
Metric The value of the route’s MED attribute. If the route does not have a
metric, this field is blank.
LocPrf The degree of preference for this route relative to other routes in the
local AS. When the BGP4+ algorithm compares routes on the basis of
local preferences, the route with the higher local preference is chosen.
The preference can have a value from 0 – 4294967295.
Weight The value that this switch associates with routes from a specific
neighbor. For example, if the switch receives routes to the same
destination from two BGP4+ neighbors, the switch prefers the route
from the neighbor with the larger weight.
Path The route’s AS path.
