Minutes IETF 71 meeting, Philadelphia Taken by Samita Chakrabarti. Wg status Analysis of IPv6 link models for 802.16 based networks rfc 4968 IPv6Cs rfc 5121 EthCs and IPv4Cs drafts are next Remaining WG items: IP deployment over 802.16 networks to illustrate the IP deployment sceanrios including IPCS and EthCS on WImax and Wibro Intial draft by Dublin Put your name as contributers Jari - how is the deployment doc different from V6OPS document ? V6OPS document has similar considerations. Is it worth doing it here additionally here? Max - How Wimax is deploying - perhaps cut-n-paste from Wimax doc Chairs : Will ask mailing list whether we develop this doc or not Syam - IPv4Cs document presentation Q : what if a host initiate an ARP packets? Gabriel - Do not send ARPs Text on NAT was removed. Default MTU (2 approaches) Jari - 1400 is the way to go; no mechanism to know the default MTU normally. If the client DJ Johnson is submitting in 802.16 to use TLV to negotiate the MTU value at L2 layer. It is between MS and BS. Wes George: for 1500 MTU Max - How 1400 bytes working in this case. Use considerations that fragmentation can happen between BS and ASN-GW Wes - Use 1500byte and do Path MTU to get the MTU on the path from ICMP Comment - Base station can never respond with ICMP packet Question - Why 1400 bytes? Show some calculation. GRE + ESP (transport mode ) 1440 --> recommended 1400 bytes GRE + ESP (tunnel mode) 1420 ---> recommended 1400 bytes Max: ASN-GW BS link is ethernet and it is traffic engineered. So, he is for 1500. Conclusion : no decision ; take it to the list EthCS MTU Main issue: VLAN'ed ethernet For GRE tunnel : No issue. Clarified Appendix A and editorial fix Step forward - Many reviews (text tweaking) Conclusion: I-D is ready for IESG review
