Each bit can represent an attribute of the link (such as whether it is encrypted or not) or a managed policy. There is no specific syntax for this 32bits . Each bit can be set to the latter without moving it. The network designer can think of specifying a specific meaning for a particular bit as needed .

Therefore the NSAP address is at least 10 bytes. In the CISCO IOS in, the NSAP configured dotted 16 hexadecimal form. The AFI value of 49 can only be used locally, and is the reserved private address space defined by RFC1618 .

System Id The data packet is stamped by A , and the TTL value of the label header is copied to the TTL in the IP header (of course, minus 1 first ), and as the data frame is transmitted in the MPLS network , the TTL value in the MPLS header is decreasing to 0. Then discard until the data frame out of the MPLS domain, then the TTL in the IP header will start working. At the time of outbound, the TTL in the tag header is decremented by 1 and copied to the TTL in the IP header .
