Dear All
I have few queries.
I have gone through all drafts and RFC 3056,2893,
But still i am not able to under stand
HOST1 and HOST2 are in different networks and
having IPv6
addresses HOST1 send one tunneled IPV4 packet <Encapsulated IPV6 UDP packet> to the HOST2
(Before sending the tunneled packet out, Will the
HOST1 send tunneled mulitcast NS to HOST2 ?<For Reachability Confirmation>).
addresses HOST1 send one tunneled IPV4 packet <Encapsulated IPV6 UDP packet> to the HOST2
(Before sending the tunneled packet out, Will the
HOST1 send tunneled mulitcast NS to HOST2 ?<For Reachability Confirmation>).
1.
PS:2893-If an implementation provides bidirectional configured tunnels it MUST at least accept and respond to the probe packets used by Neighbor Unreachability Detection [for ND all new drafts and rfc3056 is reffering RFC2893.
2.
[RFC2893] SHOULD also send NUD probe packets to detect when
the configured tunnel fails at which point the implementation can use an
alternate path to reach the destination.
Please anybody can explain with examples then i will be very
thank ful
