[ipv6-wg] IPv6 filtering in an ISP environment

Hi, 

 

I'm looking for examples on what people have implemented as ingress
filtering for IPv6 prefixes in an BGP environment. 

 

I'm would like to get some sort of filter that will not require daily
maintenance based on assigned prefixes by the RIR. 

 

I'm leaning towards having some sort of filtering based on:  

 

Drop anything from bogon list

 

allow RIR PA space - between /12 - /35 

Allow RIR PI space between /32 - /48.  (For instance for the RIPE
2001:67c::/32 & 2001:7f8::/32 parts ) 

                

So basically, a bit more strict filter than allow 2003::/3 and not having to
update it daily with each assignment made J  

 

Also some insight in why you have selected to filter on a specific prefix
length is very helpful.
