Has anyone been through this one recently enough to explain the IGP redistribution to me? The solution does not appear to use the "usual" method taught to avoid loops and After staring at it for 3 hours last night I threw in the towel. Could I get an explanation of what loops we see and why, then how they're being mitigated. Specifically I am talking about the R6, R9, R7, R1, R8, BB1 side of the topology. Here is my thinking:
R7 redist OSPF ---> RIP R7 redist EIGRP 167 ---> RIP R7 redist RIP ---> EIGRP 167 R7 redist RIP --->OSPF R1 redis EIGRP 167 ---> RIP R1 redist RIP ---> EIGRP 167 R6 redist OSPF ---> EIGRP 69 R6 redist OSPF ---> EIGRP 167 R6 redist EIGRP 69 ---> OSPF R6 redist EIGRP 69 ---> EIGRP 167 R6 redist EIGRP 167 ---> EIGRP 69 R6 redist EIGRP 167 ---> OSPF I am just missing a picture of the loops here. I know I want to prevent 1 and 7 from getting their routes to each other from RIP, and I know 6 and 7 need to block some of each others, but EIGRP 69 still needs the RIP routes somehow. I may be overthinking a bit much here, but I am looking for maybe a thought process I can use here to recognize this and come up with a plan to resolve it in , say less than several hours! :)
