I don't think so, it more a matter of creating the precedent then real
savings on the routing table size.
BGP routing table entries examined: 120000
Prefixes after maximum aggregation: 76659
Unique aggregates announced to Internet: 57689
Total ASes present in the Internet Routing Table: 14519
Origin-only ASes present in the Internet Routing Table: 12614
Origin ASes announcing only one prefix: 5690
Transit ASes present in the Internet Routing Table: 1905
Transit-only ASes present in the Internet Routing Table: 65
Average AS path length visible in the Internet Routing Table: 5.3
Max AS path length visible: 17
Illegal AS announcements present in the Routing Table: 12
Non-routable prefixes present in the Routing Table: 0
Prefixes being announced from the IANA Reserved Address blocks: 24
Number of addresses announced to Internet: 1181077033
Equivalent to 70 /8s, 101 /16s and 206 /24s
Percentage of available address space announced: 31.9
Percentage of allocated address space announced: 57.9
Percentage of available address space allocated: 55.0
Total number of prefixes smaller than registry allocations: 55671
So, if all had a IPv6 delegation, we would have 14519 routes, of which
12614 would be multihomed. Compared to 120k. What are are missing is
the number of prefixes announced by origin-only AS:es. Philip, are you
lurking here? Can that be added?
