itojun, all,

Thanks for the reply on SLIP.  I have configured PPPD with IPv4 between 2 peers.  I can ping between the 2 peers using PPPD.  Now I am trying to set up PPPD between two peers using IPv6. I can start the PPPD daemon on the 1st PC, but it gives the following error on the IPv6 address when I start the PPPD daemon on the second PC. Could you suggest on this error?

Error:
/netbsd: in6_update_ifa: prefixlen must be 128 when dstaddr is specified
pppd[222]:sif6addr: ioctl(SIOCAIFADDR_IN6): Invalid argument
pppd[222]:siftaddr failed
