P: I assume you are referring to Example 2. No, the NetBIOS
broadcast/functional address is only necessary
if NetBIOS is being used. It is not necessary if using SNA. This is
stated in the explanation of example 2.
The access-list without the NetBIOS functional address will block any
NetBIOS Name Query to
remote peers and hence to all hosts. In this example only one host's MAC
address was specified (NMC2)
in the access-list. At the bottom of Example 2 the other host (NMC1) is
shown as filtered after the addition of
the NB functional address to the access-list.
The IS-IS Authentication paper has been modified to include a note on IS-IS
MD5 authentication and
should be updated on the web site soon. Thanks for the original question.
Hope these tutorials/papers are of use in your studies.
Cheers, Fred
