The first unsolicited NA (O=0) is allowed because there are cases (think predictive handovers) where the router may be buffering traffic for the MN, but it needs some signal from the MN to inform it of its arrival (the NS doesnt' have enough information). The NA O=0 will be enough to get

Re: [psg.com #245] Mixed host/router behavior

2004-07-29 Thread Erik Nordmark
I see the point in that we should try to fill in the gap between the reality and 2461bis/2462bis. However, I still don't see if this means we need to introduce the new notion of IsRouter as a per interface variable, allowing the mixed host/router behavior. In fact, the fact you are not

Re: RFC2461bis: Semantics of advertising interface

Major issue: RFC 2461 actually says that in 6.2.2: - enabling IP forwarding capability (i.e., changing the system from being a host to being a router), when the interface's AdvSendAdvertisements flag is TRUE. This is not how I recall the intent when we wrote the

I think the high-order question is whether mixed-mode implementations exist or whether folks are working on building such things. If not we can limit any text in 2461bis to what's needed for folks to not be confused by the footnote in rfc 2460 about per-interface

RE: RFC2461bis: Semantics of advertising interface

It seems like in 2461bis-00.txt that the introduction of IsRouter in 6.2.1 is inconsistent with the text in 6.2.2 about AdvSendAdvertisements. RFC 2461 reads as if a node "advertises" itself as a router (by sending RAs and setting the R-flag in NAs any time

IPv6 addresses inside an NSAPA issues

2004-07-29 Thread Pandey, Arun
Hi, RFC 1888 section 'IPv6 addresses inside an NSAPA' does not provide a way to put the tcp port number inside the NSAP. Whereas for IPv4 addresses `RFC 1277 section 4.5 - TCP/IP Network Specific Format` specified a format that allowed the port number to be also specified. For certain
