ISIS authentication question...

Hi all,

I'm working through IPX lab 6 right now. On task 2.2, it states:

"Using minimal configuration, enable authentication for all L1 links. The
password to use is "ipexpert"."

The solution guide configures a key-chain and then sets the L1 auth type &
key-chain reference under router isis.

That's six lines of config per device, totaling 18 lines config.

Is there a reason setting "isis password ipexert level-1" on each of the
four interfaces would be incorrect in this scenario?

This solution requires 4 total lines of config, and I see nothing in the
wording to indicate anything more than Hellos/Adjacencies would need to be
protected.

Thanks,

Eric
