If this node has been known to publish unreliable routes in the past, wouldn't any upstream nodes just put some preventative rules to ignore it / blocklist it?

If this node has been known to publish unreliable routes in the past, wouldn't any upstream nodes just put some preventative rules to ignore it / blocklist it? Or is that not feasible?
- dilyevsky 3y agoYes before RPKI especially and still now this technique is commonly used but not even every T1 (backbone) network had done that correctly in the past, hence outages.
- hnarn 3y agoBy T1 I assume you mean “Tier 1”, not to be confused with https://en.wikipedia.org/wiki/T-carrier https://en.wikipedia.org/wiki/T-carrier
- dilyevsky 3y agoheh yeah tier 1 provider, not t1 line. Blast from the past - I still remember people bragging about their 1.5Mbps T1 connections.
- phara0h 3y agoAh I used to be so jealous of people with their T1 connections while I was stuck on a 56k dial up connection trying to play Unreal Tournament '99. Good times.
