Dear gary,
Thanks! obviously, I'm not very clear about spanning-tree
parameters.
I just doubt that am I correct to put the loopback into routing
process, and just put it into area 0 in ospf domain.
Regards,
Howard

Ipexpert labs have a habit of phrasing questions like this to
determine if
you know your stuff or not.
For add loopbacks as necessary
watch out for redistribute connected.
For BGP only R5 and R6 have an ebgp
peering to R7 in AS 500. The neighbor
10.10.10.7 local-as 600 no-prepend
should satisfy the requirement.
