>Description:
Had Following problem in IPV6 imlementation
| Linux |-<eth1>------------------<rl0>-| FREE BSD |
Sent an ping6 request from Linux to FreeBSD
Got Ping Echo Reply
Now deleted the interface IPV6 adrress from the FREEBSD Cache by
# ndp -d <ipb6AddressOfLinuxEth1>%rl0
Then send continuous ping request ( Echo request from linux , eth1 ) to FreeBSD
FreeBSD not sending any neighbor soliciation message.
Finally no Ping Reply back msg from FREEBSD to Linux.
Conclusion : FreeBSD is not initiating Neighbor solicition message in response to ICMPV6 Echo request if Neighbor cache is empty.
