Subjectkernels > 2.1.14 can't /sbin/route add -net 127.0.0.0
Date

It looks like there is some problem with
kernels greater than 2.1.14 and the loopback:

[meyer@endor:~] 1% netstat -rn
Kernel routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
128.223.72.0 0.0.0.0 255.255.255.0 U 32767 0 0 eth0
0.0.0.0 128.223.72.1 0.0.0.0 UG 1 0 0 eth0
[meyer@endor:~] 2%

[root@endor:/home/meyer] 4# /sbin/route add -net 127.0.0.0
SIOCADDRT: Invalid argument
[root@endor:/home/meyer] 5#

As a result, if I try to run a multicast application,
I get

[meyer@endor:~] 4% setsockopt - IP_ADD_MEMBERSHIP: Network is unreachable
setsockopt - IP_ADD_MEMBERSHIP: Network is unreachable
