Please bear with me on this...
R1 is configured as a multipoint interface to r2 and r3. In this lab r3 didn't use R1 as it's DR bridge, it used cat. If r3 had used r1 as it's DR bridge the ping from r6 to 3's bvi would have failed. This is what I'm experiencing. I think it's because the interface on r1 is receiving both r2 and r3 on the same sub interface and will not send packets back out those interfaces, due to the switching rule (packets in, forward out all ports except the one it entered on). I think that's why r6 cant ping r3 know that r3 is using r1 as it's DR. Does anyone know how I could get this to work, without using different sub interfaces?
