Masahiro Ariga again,
P.S.
I wrote the next mail on 12/13,1999.
At that time I appended rc.conf.In it,the next line is mis-spelled "YSE"
instead "YES".
gateway_enable="YSE" # Set to YES if this host will be a gateway.
I guess it happened during I copied it for mailing.
So I re-transfer the correct rc.conf.

Also,after that mail,one more problem happened.
I installed tcpdump in order to dump packets.
I succeeded the install,but when I tried to run it,next error happened and
could not run it.
tcpdump:/dev/bfp0:Device not configured.
Then,I inserted next line in my config file,and recompiled kernel and tried
again to run tcpdump. But it reports the same error .
pseudo-device bpf 3
I don't know it is related to my previous multicast problem.
And one more thing,I tried netstat command,the result is as follows,
#netstat -rn
