On the AMSIX peering LAN there is more than 100pps of ND traffic (at least 
there was when we checked). Since they do not do IPv6 multicast 
intelligent handling (MLD snooping I guess) certain highend (legacy) 
router platforms run into trouble because all these packets are punted to 
RP.

Implementing access list that filtered all multicast traffic the linecard 
didn't actually subscribe to, solved the problem.
