Re: pim session behavior at address-list option disappears

Chris,

Thank you very much for your quick response.

I understand that PIM neighbor is kept, but the address
list is updated to the latest information, i.e. no
secondary address, right ?

And what about the existing mFIB for which the secondary
address received previously was used to determine RPF ?

Regards,
-Susumu
