Implementation issues

  • [Done] HBH processed by default and limited to IOAM. Risk of DOS attack
  • Disable MLD by default
  • Disable sending RA by default
  • Add more states in ND
  • Move TTL check. Currently don't before locally received packets.
  • Drop forwarding of packets with invalid source (::, ::1)
  • Handle link-local addresses in applications, e.g. ping. Ensure packets are not forwarded outside of zone
  • Use the flow label and 3 tuple ECMP by default
  • Add source dependent routing support
