merge paths on gives syntax error

[Jan Matejka]

Hi Eelco,

use the iproute2 tool:
# ip route show

Testing this on my workstation:
# ip route add 66.66.66.66/32 nexthop via 55.55.55.1 nexthop via 55.55.55.3
# ip route show
...
66.66.66.66
	nexthop via 55.55.55.1  dev du weight 1
	nexthop via 55.55.55.3  dev du weight 1
...
# route -n
...
66.66.66.66     55.55.55.1      255.255.255.255 UGH   0      0        0 du
...
