Hi Anjanish, There is no contradiction. The intermediate nodes which are to be traversed will be listed as the destination address in the IPv6 datagram in the repsective segments and hence they can process the Routing header. Say H1 wants to talk to H2 using the route H1->R1->R2->R3->H2

Hi Margaret, thanks for your prompt response. I still do not understand how does the fact that a Hinden/Haberman address is globally unique, removes the need for a zone id/ site id. How does it settle with paragraph 6 of the Hinden/Haberman ID? ("site boarder routers SHOULD NOT forward any packe

Hi All, One statment in RFC 2460 Looks contradictory, to the behaviour of Routing Header processing. One Page 05. Sections 4. The below para says : - "With one exception, extension headers are not examined or processed by any node along a packet's de
