IPv6 Redistribution, Stub and Total Stub configuration, and some gotchas to watch for on exam day!

I was going to bring R1 in on this with a Point-to-Point Serial cable, to make the Topology look a little less pathetic than the usual all out routers everywhere model, however for these topics I only need these 3 - Though I may need to for further IPv6 studies. So far I've confirmed the … Continue reading IPv6 Redistribution, Stub and Total Stub configuration, and some gotchas to watch for on exam day!

Part 4: Found an IOS bug on R5, and found why IPv6 doesn’t work over my NBMA, so I won’t be able to lab it :(

I'm thinking it has to be something on that frame switch so we'll dig into the guts of that, but I start off with R5 (not in this Topology in which you will see why), just to get SOMETHING going for R1. As you may not know from previous labs, R5 is attached to R1 … Continue reading Part 4: Found an IOS bug on R5, and found why IPv6 doesn’t work over my NBMA, so I won’t be able to lab it 😦

Part 3: Fixing the “ATTEMPT/DROTHER” issue, but still failing at the end

So through begging all over on Cisco support community and other tech forums, someone had pointed out that my running config appears to be missing the frame map statements, and I just facepalmed so hard I might have just smacked myself. Once more, if you use templates that setup "base configs" like ip addressing and … Continue reading Part 3: Fixing the “ATTEMPT/DROTHER” issue, but still failing at the end

OSPFv3 PtP networks, adding IPv6 addressing on interfaces, and more IPv6 info / configs in general (good stuff)

So this video I am working on now is regarding point-to-point networks, which I didn't think that if I were going from 2-3 with the SW1 between then it would be an "Ethernet segment" however R3 and R4 are directly connected via Fa0/1 so that would be a point-to-point so I may be re-covering the … Continue reading OSPFv3 PtP networks, adding IPv6 addressing on interfaces, and more IPv6 info / configs in general (good stuff)

IPv6 / OSPFv3 configuration and explanation along the way!

As illustrated above, OSPFv3 (OSPF for IPv6) and OSPFv2 (OSPF for IPv4) can co-exist in harmony on one router, as two completely separate processes, without interfering with each others operation (just like our recent VRF discussion). Being that OSPFv3 is configured on an interface by interface basis, it does not use network statements in router-config … Continue reading IPv6 / OSPFv3 configuration and explanation along the way!
