As previously mentioned I believe, this will be a multi-part lab in which I will configure "Multi-Point" 2-way Redistribution / Policy-Routing / Distribute-Lists / Route-Maps / and troubleshooting all along the way. Here are a few things I know I want to achieve over the several parts of this lab: Authentication deep dive for … Continue reading Part 1: Setting up the new, bigger, and better lab to configure everything we’ve learned up to this point!
Still working with the same Topology seen above, I want to round off the Policy Routing videos to see if I can bring that into some scenario or freestyle lab, and see how crazy one can get with Policy Routing. The first thing to note that I have amazingly not known at all until this … Continue reading The extended traceroute command, and Local Policy Routing Configuration!
As seen in the previous look at policy routing using a standard ACL, it led to sub-optimal routing due to only routing on the source, and not both source and destination addresses - for this we will use an Extended ACL to correct. So I took the old commands off, nothing fancy: R1(config)#no access-list 5 … Continue reading Using Extended ACL’s for Policy Routing to overcome sub-optimal routing
Due to some winter illness and the fact that I had to swap cables with my home production network to make this topology work, it took some time to physically put this all together, so getting it setup just to lab was quite the undertaking but once all said and done I have this to … Continue reading Policy Routing with a Standard Access-list, sub-optimal routing (Ugh)
This will be the intro to the pointers or theoretical stuff to know before diving into configuration and troubleshooting. On Chris's initial Topology he has 3 routers connected on one common subnet, so I will need to review the configuration's to understand what the actual networks are or if there is a reason he … Continue reading Intro to Policy Routing (PBR) and Local Policy Routing, new Topology soon!
Boy do I feel stupid. After spending hours of scratching my head at why this is not working yet, as OSPF seems to be gettings tags but RIP is not, that is when I really put my work under a microscope and found that I was applying OSPF2RIP in OSPF router config and the other … Continue reading Part 3: Finally got Route-Maps for Redistribution working correctly, important notes within on how!
So to begin this, right off the bat I am having trouble seeing some routes on R1 from R4, as I just did a "wr er" and reloaded / reconfigured it to be directly connected. However, on R4, things couldn't possible be going better, I created lo5 and lo15 to simulate those networks from the … Continue reading Part 2: A struggle getting RIP on R1 to get any Redistributed OSPF, may need router reconfigs
Above is a "Single-Point 2-way Redistribution" in our network, which is honestly not going to (probably ever) present a loop from sharing or "leaking"routes back into their own domains, however route-tagging usefulness goes beyond just Redistribution as we will see it I assume in the next topic up PBR (Policy Based Routing / Policy Routing) … Continue reading Part 1: Route-Map tagging for 2-way Redistribution, a prevention mechanism for routing loops!
So where Part 1 of this lab left off, we learned that without that "catch all" clause at the end permitting traffic, then it is dropped like an ACL would. Going through the 2-way Redistribution video, I also learned that sequence #'s do also work exactly like ACL's, so you will want to plan your … Continue reading Part 2: Understanding Route-Map Sequence significance, Clauses, and lots of details to finish this Route-Map lab!
**Updated country hit list, up to 160 countries of the 195 total countries in the world checking out (some regularly) my notes, that is 82% of the world!!* First and foremost I am always amazed and humbled by the amount of traffic I get from almost every corner of the world, I hope my ad-free … Continue reading Now at 160 / 195 total countries with me on the CCNP Grind, that is 82% of the world, fellow Cisco geeks unite!!! 🙂
Being that the two way redistribution training gets into route tagging and other fun concepts, I want to just get an easy lab configuration under my belt to get myself started, and will just be working with R3 and R4 as no other routers can see the OSPF routes except R3 after I do this: … Continue reading Part 1: RIP into OSPF 1-way Redistribution, Route-Map lab
I have to say that going from Distribute-Lists where you are just applying standard ACL's to Redistribution is like little league softball compared to Route-Map configuration for them. I planned to study them more before throwing a post up with some lab work getting done, but this is a really exciting topic to me, as … Continue reading An Introduction into the wonderful world of Route-Maps, setting the lab
Being that this lab is already set (see previous post), my EIGRP routes are all showing on R2's ABR R3 as shown below, I am going to write a couple of of Distribution lists. A main point again about Distribute-Lists: You can have more than one, but the more specific dist-list always takes precedence So … Continue reading Finishing look at Distribute-List’s, back to Myself Inc Topology with my new knowledge!
So I must preface this by saying it is the most beautiful day MN has seen in weeks, the sun is out and it's probably mid-high 20's, so it is the perfect day to open the shadows to let the sun in and sit in front of the command line! Ran out and got some … Continue reading Setting up EIGRP to OSPF Redistribution lab, excellent review of concept for exam day
So I am really reeling it back in here, as I think I got over ambitious without learning the basics, so I am just going to do a simple configuration here. For R2, I want to make a Summary route based on the following network numbers: interface Loopback1 ip address 22.214.171.124 255.255.255.255 interface Loopback101 ip … Continue reading Configuration of “Distribute-List”s and 1-way redistribution, with success!!
