Hey Scott,
I built for myself a simple mnemonic to remember
deny target
deny target & source
deny other & source
permit other --> add source
permit source --> set tag of source
my biggest fear is running into a nasty multiprotocol redistribution
scheme and having something be missed. I spent a while thinking about
this tagging scheme and scenarios where it would not work..couldn't
think of any yet.
