Analysis of the ‘Maximum Length’ Option in Certification ROAs
by Alex Band 20 Apr '11

20 Apr '11

[apologies for duplicates] Dear colleagues, We just published an article on RIPE Labs on the usage of the 'Maximum Length' option in ROAs. We compared all the prefixes in the Repository which are covered by a ROA to the prefixes seen by RIS. It gives a good indication how people are using this option, and what the effects are when people base routing decisions on validation results. You can read the article here: https://labs.ripe.net/Members/AlexBand/using-the-maximum-length-option-in-r… Kind regards, Alex Band Product Manager
