Doesn't the following indicate that neither does Verizon?
In this case it appears Verizon had little or no filters, and accepted most if not all BGP announcements from Google which lead to widespread service disruptions. At the minimum Verizon should probably have a maximum-prefix limit on their side and perhaps some as-path filters which would have prevented the wide spread impact.
- notyourday 9y agoIt accepts it from Google because Google does not register its prefixes. If I do not know what you should announce to me I have two choices: filter everything our making PNI useless or presume you are not a dolt and that you are only going to announce what you should transit which would work if you filter your peers. Except that Google does not believe in filtering its peers either which means that effectively whoever peers with Google has to presume that whatever Google announces is fine.
