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.

    RIB/FIB ratio (91183/23311)3.9116
      Valid entries91183

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.

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.

AS Paths

The time trend of the number of unique AS Paths advertised within the BGP table. The associated metrics look at trends of average path length, and BGP table entries per path.

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.

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.
