They may not want to pollute the global routing table with these entries. It has a cost for everyone. If we all did this, the table would be a mess.
2. Why almost all carriers did not filter the leak on their side, but waited for "a better weather on Mars" for several hours?
There’s several major issues here - Verizon accepted garbage from their customer - Other networks accepted the garbage from Verizon (eg: Cogent) - known best practices from over a decade ago are not applied I’m sure reporters will be reaching out to Verizon about this and their response time should be noted. It was impacting to many networks. You should filter your transits to prevent impact from these more specifics. - Jared https://twitter.com/jaredmauch/status/1143163212822720513 https://twitter.com/JobSnijders/status/1143163271693963266 https://puck.nether.net/~jared/blog/?p=208
