1	This solution uses a System ID of 0000.1234.abcX, where X is a number that makes the router unique within the IS-IS domain. The System ID is six octets, which is required by Cisco IOS. The minimum NET length is eight octets, one of which is the SEL, so the area address is a one-octet number corresponding to the area number shown in Table 10-6.
