R2-F0/0. SHOWiT has ip igmp join-group 229.9.9.9. I have no idea why.
R2 filters out supernet summary route during redistribution from EIGRP to OSPF. Is this really necessary?
I forgot the IPv6 split-horizon stuff on R1. In fact, I did not test the IPv6 properly. So much so, that my IPv6 spoke-to-spoke frame maps were missing on R3 as well. However, I did not spray the broadcast keyword quite as liberally as they did.
They had no peer neighbor-route on their PPP link R3<–>R5 and I did not. I don’t think this matters too much, does it?
