Routing header Next Header (8 bits) Header Ext Length (8 bits) Routing Type=0 (8 bits) Segments Left (8 bits) reserved (32 bits) address[1] (128 bits) address[2] Next Header identifies the next header in the chain of headers. ... address[n] Header Ext. Length. - number of 64 bit words (not including the first 64 bits). Routing type=0, is the generic routing header which all IPv6 implementations must support. Number of Segments is the number of segments left in the list (between 0 and 23). Maguire Routing header 10: 30 of 54 maguire@kth.se 2010.03.21 Internetworking/Internetteknik
