Milo - I just recvd an email from one of our very best routing
protocol guys at Juniper, and he made some sense out
of what you saw in the manual on page 7.
He noted, "A route with 2 next hops is preferred over one with only
a single next hop, since it is more survivable. So, if
you have a BGP route from two BGP NextHop routers, and
you have one IGP nexthop to router A and two IGP nexthops
to router B, we'll prefer the route from B.".
On reflection, this makes a lot of sense.
So, while my last email was accurate, albeit lengthy,
I stand corrected. There is not documentation error.
My thanks to Paul Goyette for the clarification.
Good Luck!
Bob O'Hara

Subject: [j-nsp] route selection
List,
I have been reading through some info regarding path
selction as listed on page 7 of the routing and
routing protocol documentation. In the list of how
JUNOS selects the route to make active, number 8 says
"Prefer paths with larger number of next hops".
If someone can lend some interpretation to this I
would appreciate it. Each time I attempt to clarify it
myself, I hit the brick wall and find that I am human
and bleed.
thanks in advance for your replys.
