The message from Joseph Reddy is important and makes sense. I have a remark to that message as well: when the RH is built as you suggest (BR inserts is own address in the RH (the one on which interface? an ll address?)) it may be questionable about how the AH authentication header is applied

Hi Joseph, I presume that you are not using IP-in-IP tunneling. If you were using IP-in-IP tunneling as the draft suggests, then the source address of the inserting router is included in the outer IP header. Your comment seems relevant to draft-hui-6man-rpl-headers-00, which describes what

IMHO, IPv6 links that occur in the network (even tunnels) should try to do better than 1280 if possible. Otherwise, VPNs/tunnels that ride over the links may see a too-small MTU resulting in IPv6 fragmentation. Granted, doing better than 1280 may be difficult for some links. Thanks - Fred

Re: [AVTCORE] RTP and UDP checksum=0

2011-04-22 Thread Philip Zimmermann
I think it should use the checksum field. It is generally a bad idea for one layer to neglect its usual built-in error-checking duties because it assumes another layer will handle it. Let me draw an analogy from the crypto world, we don't use weak 56-bit DES as our PGP keys because we assume

Hi, I have a comment on the rpl-routing-header draft that was noticed during interoperability testing conducted by the zigbee alliance. In the most common usage of this header, the border router inserts a source routing header with the full set of intermediate nodes before forwarding it

RE: PMTU blackhole detection

2011-04-22 Thread Timothy E. Enos
I concur with Fred that IPv6 links over the network should have an MTU 1280 if possible. The fragmentation that could occur at say the head-end of a tunnel seems enough of a contraindication in general for it having a 1280 MTU. Efficient use of (up)links is clearly another consideration when

Many thanks to Suresh Krishnan for excellent minutes! I'd really like to echo that. It's a pleasure to see minutes that summarise discussions in good English, rather than just record he said/she said. Regards Brian Carpenter
