What makes you mark routes as ORIGIN: IGP vs ORIGIN: EGP?
I just checked out the latest routeviews snapshot to see what the origins of various routes were set to. The command line $ bzcat oix-full-snapshot-latest.dat.bz2 | sed -e 's/.* //' | sort \ | uniq -c | sort -nk1 Gave me a bunch of crap from overly-long lines, and then 9091 e 682087 ? 7560175 i
Which means that out of 8,251,353 routes in routeviews, only 9,091 are marked as ORIGIN: EGP, while 682,087 are not configured as one or the other, and the other *7.5 million* are marked ORIGIN: IGP.
So my question is: What do people use ORIGIN: EGP vs ORIGIN: IGP to distinguish? What makes a route EGP vs. IGP to you?
Mostly load balancing, thought manually setting it via route maps. -- TTFN, patrick
