I have added loopbacks to simulate some EIGRP Networks behind our two Stub routers, to demonstrate some different concepts such as Summary Address and Leak-Maps, however I will start right at the beginning of EIGRP Stub routing and what it does. My labbing kind of got long winded but I really wanted to drive some … Continue reading EIGRP – Stub review, default behaviors, basic configuration, Summary-Address and Leak-Maps config, and verification!
I have a confession to make - While studying MPLS I largely overlooked the configuration of the Provider Edge because of its complexity and ease of breaking all routing (and probably reversing time). I intentionally used my MPLS Lab for ENARSI 300-410 study with new IP Schemes / CE Protocols to challenge my knowledge of … Continue reading MPLS – A necessary closer look at the PE Router settings (VRF / BGP / VPN / Address Family) to see how to setup for new lab!
Above is the full scope of the Topology that will be configured by the end of this, utilizing all different protocols for CE to PE, mainly to demonstrate it flexibility with accepting IGPs for all walk of life which is what this blog is all about 🙂 NOW, I had went ahead and used Keith … Continue reading MPLS – Now to apply the Network Ninja troubleshooting to get these CE Routers talking across the MPLS Network!
We will stick with the same old Topology to finish EIGRP review off, I have one more article after this, then I really need to double time some other topics before exam day to freshen up the ol' steel trap! Now a couple of things that separates "Original mode" from "Named mode" EIGRP is: It … Continue reading EIGRP: Named mode, a whole new type of EIGRP mode, with all new configurations and explanations including “address-family”s!
