Re: OSPF

Like Keegan wrote, the next-hop in BGP is there to fulfill a different need
and is set by the router who originally advertised the route into the AS.
With OSPF on the other hand, each router has a table of all the links in the
area and then builds routes and computes next-hops based on that. This
means that any next hop for a given route would generally be set by
manipulating the values that OSPF uses to compute next hop such as cost or
intra/inter areaness (is that a word?) of the route.
