	AS131072 IPv6 BGP Table Data
	BGP data obtained from AS131072. Report last updated at Sat Jun 24 04:45:01 2017 (Australian Eastern Time).		Other BGP Metrics

Active BGP entries (FIB)

Table Size Metrics

The trend of the size of the BGP Forwarding Table (FIB) and the underlying BGP Routing Table (RIB). The RIB/FIB ratio is a function of the number of BGP peering sessions at the sample point. Some RIB entries are marked as unusable as an outcome of protocol operation, and these categories of unusable advertisements are tracked.

FIB / RIB Table Reports (plots)	Data Sets(txt)
Active BGP entries (FIB)	40558	Change in FIB Size	-56	Change (%)	-0.138
All BGP entries (RIB)	78903
RIB/FIB ratio (78903/40558)	1.9454
Valid entries	78903

Address Span Metrics

The total span of address space advertised in the BGP table, and the relationship of this value to the number and size of address prefix objects in the table.

Address Space Reports (plots)	Data Sets(txt)
Total address space advertised (/64 equiv)	428884144164864
Total address space advertised (prefix)	15.3924
Percentage of IPv6 space advertised (428884144164864/18446744073709551615)	0.002325
Average address span	10574588100
Average address span (as prefix size)	30.7001
Average prefix length	41.4206

More Specifics

The characteristics of more specific advertisements - where an advertisement is associated with a sub-span of address space of another advertisement. The metrics also look at the degree of similarity of the AS paths of the specific advertisements to the encompassing aggregate.

AS Numbers

The time trend of the number of unique AS numbers advertised within the BGP table. The associated metrics characterise AS's into origin only, transit only, or mixed (origin and transit), and also look at the trends of advertised address space as related to the number of ASes.

BGP Update Reports

Compares the current BGP Table with the previous table and reports on the number of changes in the FIB. These changes are further categorised into announcements, withdrawls and path changes, and further categorised by prefix length.

Path Updates - Breakdown by Update Type

Examines those updates that involved a change of AS Path and breaks this down into five categories:

A change of origin AS (origin)
A change in the origin's nexthop AS (remote change)
A change in the transit AS path (transit)
A change in the firsthop AS (Local change)
A change in AS prepending (Traffic Engineering)

AS Connectivity Reports

This set of reports lists all visible AS's using a number of ordering criteria. The reports order AS's by the total span of addresses originated by an AS, the total span of addresses reachable via an AS, and the totspan of roiginating plus transit addresses via each AS. Each AS in an AS path has an adjacent AS closer to the sample point, and an adjacent AS further from the sample point. The number of such pairwise adjacencies is reported for each AS. The average AS Connectivity Degree is the average number of adjacent AS's for an AS.

Aggregation Reports

This set of reports lists all potential aggregation of a number of specific routes into an aggregate route. The aggregation criteria include a match of the original AS path, which may include prepended AS's, a match of the reduced AS Path, and a match on the Origin AS only. As this view is taken from a single sample point, this list is not definitive, and the report will propose potential aggregation actions which may not be feasible for the Origin AS.
