Syntax: show ipv6 bgp routes detail [<ipv6-prefix>/<prefix-length> | <table-entry-number> | age
<seconds> | as-path-access-list <name> | as-path-filter <number> | best | cidr-only |
[community <number> | no-export | no-advertise | internet | local-as] |
community-access-list <name> | community-filter <number> | local | neighbor
<ipv6-address> | nexthop <ipv6-address> | no-best | prefix-list <name> |
regular-expression <regular-expression> | route-map <name> | summary | unreachable]
You can use the following options with the show ipv6 bgp routes detail command to determine the
content of the display.
The <ipv6-prefix>/<prefix-length> option displays details about routes for a specific network. 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.
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 switch received better routes from other
sources (such as OSPFv3, RIPng, or static IPv6 routes).
•
C – CONFED_EBGP. The route was learned from a neighbor in the
same confederation and AS, but in a different sub-AS within the
confederation.
•
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 switch.
NOTE: 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”.
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
AS-PATH
For information about this field, refer to
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.
