Re: address selection and DHCPv6

For example,an interface has two an addresses, automatic-configured 1000::1/65 and manually-configured 2000::1/64,and 1000::2/64 is the on-link neighbour of the interface.We send a packet, for example and ICMPv6 echo, with a destination address of 1000::2 from the interface,then the source addre

Re: New draft on IPv6 extension headers

2006-10-19 Thread Su Thunder
If we can predict that many new extension headers will be defined in the future,a new draft for the router to recognize the newly defined extension header will be neccessary.For example,we can define a set of parameters including the Next Header value in the immediately preceding header,a list o

Re: New draft on IPv6 extension headers

2006-10-19 Thread Su Thunder
I don't think your comment is a problem.Whether a block of memory is payload or an extension header is determined by the Next Header value of the immediately preceding header, not whether the extension header is known or unknown.A node should pass an unknown extension header to the next header i

For example,the IP address of one end(Router A) of the PPP link is 1000::1/64,the one of the other end(Router B) is 1000::2/64.Suppose packet with a destination IP address of 1000::3/64 is sent from Router A to Router B.On Router B,the packet's destination IP address matches 1000::/64,then the

Hi! Let's see the following paragraph of section 4 in RFC2460. " Each extension header is an integer multiple of 8 octets long, in order to retain 8-octet alignment for subsequent headers. Multi- octet fields within each extension header are aligned on their natural boundaries, i.e., fiel

Hi every body,I noticed this issue very long ago, but I always think the byte order of IPv6 header is big endian.But I'm not so sure for the payload.If an application or user want to use little endian in the payload and it has assurance that the recipient knows this,it can use any of them.Paylo
