[c-nsp] IPv6 RA filter on Layer 2 switch with edge ports configured as trunk

Hi,

Trying to figure out a solution on how to implement an IPv6 Traffic Filter
to block RA messages on a 4948 that is configured as an L2 switch. More
specifically the edge ports are configured as trunks to an ESX host which
has many VMs (Windoze, Linux, etc). Given the trunk port config, I know I
could do a VACL, but those lack direction (input/output) so it seems like a
non-starter

Appreciate any thoughts/advice
