This is a full view from Exodus:
x.x.x.x 4 3967 243954 11543 752069 0 0 1d11h 106124
This is the same full view from Exodus if they'd practice what they
preach(ed) and apply <http://www.nielsen.net/people/christian/linx.html>:
x.x.x.x 4 3967 262248 11546 752112 26 0 1d11h 87853
There are some particularly entertaining "bogons" (well, in my mind)
in the non-abbreviated version, including:
$ /usr/local/rancid/bin/clogin -c "show ip bgp regex 3967_" border1.nyc1 > exds-routes
$ grep "/32" exds-routes |wc -l
27
$ grep "/31" exds-routes | wc -l
2
$ grep "/30" exds-routes | wc -l
293
$ grep "/29" exds-routes | wc -l
114
$ grep "/28" exds-routes | wc -l
269
$ grep "/27" exds-routes | wc -l
220
$ grep "/26" exds-routes | wc -l
275
$ grep "/25" exds-routes | wc -l
312
$ grep "> 10." exds-routes
