Displaying BGP4+ information 45 TABLE 181 Detailed BGP4+ route information (Continued) This field... Displays... Origin Weight AS-PATH Adj_RIB_out count Admin Distance 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. For information about this field, refer to Table 180 on page 1134. For information about this field, refer to Table 180 on page 1134. 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. The administrative distance of the route. Syntax: show ipv6 bgp routes detail [/ | | age | as-path-access-list | as-path-filter | best | cidr-only | [community | no-export | no-advertise | internet | local-as] | community-access-list | community-filter | local | neighbor | nexthop | no-best | prefix-list | regular-expression | route-map | summary | unreachable] You can use the following options with the show ipv6 bgp routes detail command to determine the content of the display. The / option displays details about routes for a specific network. You must specify the parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373. You must specify the parameter as a decimal value. A slash mark (/) must follow the parameter and precede the parameter. BigIron RX Series Configuration Guide 53-1001810-01 1137

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.

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.
