Hey Brad,
Could you please paste your frame-switch configuration in a reply? Also, one
thing that caught my eye was the formation of DR/BDRs in your lab. When you
have point to multipoint subinterfaces, there should not be any DR/BDRs.
Could you do a show ip ospf int s0.1 on R3, R4, and R5? Also, what is the
purpose of s0.2 on R3?
