The Tunnel destination of r1's tunnel should be the source of r2's tunnel
The Tunnel source of r1's tunnel should be the destination of r1's tunnel
The ip address that you give the tunnel's themselves doesn't really matter
as the tunnel itself is formed based on the reachability of the tunnel's
destination.
Therefore, in your example, Yes, r3 should set the destination to be r1's
loopback.

Hi all,
If I use loopback in one end, am I need to set the destination IP address
in the tunnel peer end router to be this loopback IP address? or I can set
to another interface?
For the same example, if r1 use loopback as tunnel source, is it true that
r3 should set the destination to be r1's loopback? can it be r1's serial
interface?
Thx,
BBD (Big Black Dog)

Please respond to

In fact if you've got redundant paths between the two routers, it's
preferred to use the loopbacks.

Not necessarily. You can use loopback addresses.

what is the best-way of setting Tunnel addresses..?
>>>hmm, not sure what you mena by this but the tunnel address is an ip
address that should be in a different subnet than what you already have
