Re: [OSL | CCIE_RS] Need Help in understanding sequence.

I'm not sure I understand the question entirely, but there are
fundamental differences in the commands here:

1) set ip next-hop <--- This will look at the next-hop address you
specify. If that next-hop is in the routing-table, the packet is
policy routed to that next-hop.
2) set ip default next-hop <--- This will look at the destination IP
address in the header. If you have a route to the destination in your
routing table the packet is NOT policy routed. If you don't have a
route to the destination, then you are routed to the next-hop
specified.

The logic is different, and the two commands are looking at different
fields. The first looks at next-hop and the second looks at the
destination IP address to make decisions.
