We have so far alwways invalidated VLPIs usinc an INV+SYNC sequence, but that's pretty wrong for two reasons:
- SYNC only synchronises physical LPIs - The collection ID that for the associated LPI doesn't match the redistributor the vPE is associated with
Instead, send an INV+VSYNC for forwarded LPIs, ensuring that the ITS can properly synchronise the invalidation of VLPIs.
