Re: pim session behavior at address-list option disappears

Susumo,

If you read a bit further down to 4.3.4 you will find:

"If a received PIM Hello message does not contain an
   Address List Hello option, then all secondary addresses associated
   with the neighbor must be deleted."

So you will remove the neighbor association of the secondary addresses.
You should still maintain a peering with the 'primary' address.

Cheers,

dan
