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)	1527	Change in FIB Size	0	Change (%)	0.000
All BGP entries (RIB)	8163
RIB/FIB ratio (8163/1527)	5.3458
Valid entries	8163

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)	179504438968322
Total address space advertised (prefix)	16.6490
Percentage of IPv6 space advertised (179504438968322/18446744073709551615)	0.000973
Average address span	117553660097
Average address span (as prefix size)	27.2255
Average prefix length	37.1794

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.

More-Specific Advertisement Reports (plots)	Data Sets(txt)	Percentage Reports (plots)	Data Sets(txt)
Entries advertising more specific prefixes of aggregates	293	Specifics as % of FIB entries (293/1527)	19.1880

Root Prefixes with depth 1	6

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.

Average address range span for an origin AS (pfx length)	26.7627

AS Paths

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.
