Dear all:
        It is known that only one kind of PDU hello type works as p-2-p link(broadcast has two, level-1 and level-2 respectively)
When i configure the authentication on one p-2-p link running IS-IS, the router(such as Cisco's) also give level-1 and 
level-2 option to choose. I wonder what is the rule to decide which level password configured should the p-2-p link used.
        Anyone can give some information about this part? Thanks in advance. 

thanks@regards
