IGP redistribution, after the solution i see that on R1 and R2 OSPF external routes which are resdistributed from RIP seen as EIGRP external route. isn`t that problem?
I'm running on the same problem here. As I see it there are two ways to look at this problem:
- We can leave the sub-optimal routing in place. Connectivity to those networks are not being affected, there just aking a suboptimal path. Optimal path routing is not a requirement for this section.
- We can filter the routes from being redistributed back into EIGRP if they were originated by the same EIGRP process.
Just my two cents.
I chose to filter any routes that originated in EIGRP (or behindthem in RIP) from being sent back to EIGRP. In most cases, I thinkthere's little value in telling a protocol about networks that youlearned from it in the first place. Kind of like a manual splithorizon mechanism.
I figure that if I don't allow routes originated behind OSPF to come in from EIGRP, and if I don't allow EIGRP routes to come back from OSPF, then I should be preventing really poor routing from happening.
On the topic of this initial post, my issue here was that I still needed to make sure that I was changing the distance of external OSPF to >170, as I was not getting proper path information even though I thought the rest of my configuration looked OK. R1 and R2 both appeared to have some funny things, like this route on R2:
P 188.8.131.52/16, 1 successors, FD is 2560000256, tag is 110 via Redistributed (2560000256/0)
which was being sent to OSPF rather than via EIGRP up to the RIP domain. Making the external OSPF distance 171 "fixed" that. Before I changed the external ospf distance, I was getting spotty results when trying to make sure BB1 routes and BB3 routes exited the network properly.
Is that what was being asked?
Did you mange to fix the problem. I'm experining difficulities pining B1 and B3 router from R1/R3. Although able to ping R6 s0/0 and F0/0 interface. Any idea, why?
I have solved the ping problem between R1/R5 to BB1 and BB3. It was due to R6 RIP version. R6 was running on version 1. After chaning the RIP version to 2 ping between routers are successful.
