loop-back surpression & duplicate address dedection

2005-04-28 Thread Grubmair Peter
On page 25 of 2662bis 07 draft the difficulties for loopback and dad are explainded. Maybe dedection of loopbacks (of NS) could be supported by adding a new option either as NS option or as destination header option. This option should carry a random identifier of sufficient len

possible Duplicate addresses in case of healing network partition s

In 4. Healing of Network Partitions states: Hosts on disjoint network links may configure the same IPv4 Link- Local address. If these separate network links are later joined or bridged together, then there may be two hosts which are now on the same link, trying to use the same address. To my mind

On page 59, 7.2.5 is written: -> If the Neighbor Cache entry is not in INCOMPLETE state, the receiving node performs the following steps: - It records the link-layer address in the Neighbor Cache entry. - If the advertisement's Solicited flag is set, the state of the entry is set

Hi, I have a question regarding 6.3.4 in the above neigbour-discovery draft. On page 49 it is stated, that if reachable time is not updated by new router advertisements, a host SHOULD recompute a new random reachable time value every few hours. Can anybody tell me why a host should do this ? - wha

I want to state that I personally do not like the new idea from the draft to consider total lifetimes of a temporary address in case of some RAs renew prefixes. (Previously lifetimes of temporary addresses could only be lowered by RAs). This adds additional complexity for the rather rare event of a

In the state diagram in RFC2461-bis in Appendic C, page 79, the event of receiving a NA with solicitated = 1 and Override = 0 in state DELAY is not handled. To my understanding the same treatment as in state STALE or PROBE has to be applied. To me it also seems, that the state DELAY can be treate

For Duplicate address dedection RFC2462, a node must join the solicitated-node-multicast address before Duplicate Address dedection. For verifying link-local address, this will mean, that only a tentative link-local address is available. I would like to know, which source address shall be used in M

In RFC3484 source address selection is described, which selects a source address from a candidate set by defining a total ordering onto the addresses. Typically (RCOMMENDED) the candidate set consist of just the addresses assigned to the outgoing interface. In case that all global addresses assigne

2004-05-12 Thread Grubmair Peter
I wonder how an IPv6 RAC-node gets to know any router, if it is connected in an IPv6/Ipsec/Ikev2 VPN scenario. IKEv2 configuration payload only assigns an address+ netmask and gives DHCPv6 server address, but DHCPv6 does not have any options for publishing routers. Therefore to get to know routers
