Before the "authenticate snp" option was added in 12.0(21)ST, the "area-password" and "domain-password" commands were doing authentication of the LSPs, CSNPs and PSNPs: "This password is inserted in Level 1 (station router level) link state PDUs (LSPs), complete sequence number PDUs (CSNPs), and partial sequence number PDUs (PSNP)." http://www.cisco.com/en/US/docs/ios/12_0/np1/command/reference/1risis.html#wp1017389 "This password is inserted in Level 2 (area router level) link state PDUs (LSPs), complete sequence number PDUs (CSNPs), and partial sequence number PDUs (PSNPs)." http://www.cisco.com/en/US/docs/ios/12_0/np1/command/reference/1risis.html#wp1017509

I just did this lab recently as well. I always heard that ISIS has limited authentication capabilities, but there are more configuration options than I expected.

To authenticate these SNPs, we need the "authenticate snp" option. I was convinced that with the command "area-password xxx", the LSPs, CSNPs and PSNPs were authenticated which is not true. Comments are welcome.
