Hello ,     I am new to RIPE, I was going through the RIPE 554 "Requirement for enterprise / ISP grade Layer 2 switch". I saw list of requirements like a. MLDv2 snooping [RFC4541] b. DHCPv6 filtering [RFC3315] c. Router Advertisement (RA) filtering [RFC4862] d. Dynamic "IPv6 Neighbor solicitation/advertisement" inspection [RFC4861] e. Neighbor Unreachability Detection [NUD, RFC4861] filtering f. Duplicate Address Detection [DAD, RFC4429] snooping and filtering Is there any RFC or draft compliance should be followed for the above. The RFC mentioned above are the protocol RFC and not specific to snooping or filtering. While RIPE 554 testing, what they test against? Thanx, Jags
