cycle through the port range.
pgset "udp_dst_max 9" set UDP destination port max.
pgset "mpls 0001000a,0002000a,0000000a" set MPLS labels (in this example
outer label=16,middle label=32,
inner label=0 (IPv4 NULL)) Note that
there must be no spaces between the
arguments. Leading zeros are required.
Do not set the bottom of stack bit,
thats done automatically. If you do
set the bottom of stack bit, that
indicates that you want to randomly
generate that address and the flag
MPLS_RND will be turned on. You
can have any mix of random and fixed
labels in the label stack.
pgset "mpls 0" turn off mpls (or any invalid argument works too!)
pgset stop aborts injection. Also, ^C aborts generator.
