Syntax: show ipv6 bgp routes [<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> | detail [<option>] | 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 command to determine the
content of the display.
The <ipv6-prefix>/<prefix-length> parameter displays 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.
The <table-entry-number> parameter specifies the table entry with which you want the display to
start. For example, if you specify 100, the display shows entry 100 and all entries subsequent to
entry 100.
The age <seconds> parameter displays only the routes that have been received or updated more
recently than the number of seconds you specify.
The as-path-access-list <name> parameter filters the display using the specified AS-path ACL.
The as-path-filter <number> parameter filters the display using the specified AS-path filter.
Status The 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.
•
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.
•
E – EBGP. The route was learned through a switch in another AS.
•
H – HISTORY. Route dampening is configured for this route, and the
route has a history of flapping and is unreachable now.
•
I – IBGP. The route was learned through a switch in the same AS.
•
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.
AS-PATH The AS-path information for the route.
