Displaying BGP4+ information
45
The detail <ipv6-prefix>/<prefix-length> <network-mask> parameter displays detailed information
about the specified RIB routes. If you do not specify this parameter, a summary of the RIB routes
displays. You must specify the
<ipv6-prefix> parameter in hexadecimal using 16-bit values between
colons as documented in RFC 2373. You must specify the <prefix-length> parameter as a decimal
value. A slash mark (/) must follow the <ipv6-prefix> parameter and precede the <prefix-length>
parameter. You must specify the <network-mask> parameter using 8-bit values in dotted decimal
notation.
This display shows the following information:
For example, to display details about all RIB routes for neighbor 2000:4::110, enter the following
command at any level of the CLI.
TABLE 203 Summary of RIB route information for a BGP4+ neighbor
This field... Displays...
Number of RIB_out routes for a
specified neighbor (appears only in
display for all RIB routes) The number of RIB 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 Status column of the display. The status
codes are described in the command’s output.
Prefix The RIB route’s prefix.
Next Hop The next-hop switch for reaching the route from the switch.
Metric The value of the advertised route’s MED attribute. If the route does not
have a metric, this field is blank.
LocPrf The degree of preference for the 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.
Status The RIB route’s status, which can be one or more 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.
E – EBGP. The route was learned through a switch in another AS.
•
I – IBGP. The route was learned through a switch in the same AS.
•
L – LOCAL. The route originated on this switch.
AS-PATH The AS-path information for the route.
