ispunity setup error - Error: an inet prefix is expected rather than "equalize".

[rtdp]

This is on openSuse 12.1 machine.
I was trying to connect with two of the ISPs. Below is ispunity setup command log -

Command that can reproduce this error -

linux-vai9:~ # /sbin/ip route replace equalize default  nexthop via 220.224.141.129 dev ppp0 weight 1  nexthop via 192.168.1.1 dev wlan0 weight 1
Error: an inet prefix is expected rather than "equalize".

Command that can make it work -

linux-vai9:~ # /sbin/ip route replace default scope global  nexthop via 220.224.141.129 dev ppp0 weight 1  nexthop via 192.168.1.1 dev wlan0 weight 1
linux-vai9:~ # ip route show
default 
nexthop via 220.224.141.129  dev ppp0 weight 1
nexthop via 192.168.1.1  dev wlan0 weight 1
192.168.1.0/24 dev wlan0  proto kernel  scope link  src 192.168.1.137  metric 2 
220.224.141.129 dev ppp0  proto kernel  scope link  src 115.242.67.32 

Let me know if some other details required.

hi Ratandeep,

We'll try to reproduce this bug and fix it asap.

man ip says:
"equalize only works if the kernel is patched."
for the records: ip multipath (the entire program) only works if enabled in the kernel:
CONFIG_IP_ROUTE_MULTIPATH=y
