EIGRP – Metric review, random “offset-list” lab for Path Selection, Feasibility Condition and Variance discussion, and will PBR config override offset-list?

Above is the lab that this post turns into pretty fast once the MPLS is live and installs itself around on EIGRP routers, lots of good info, I advise trying to make through this post if you are rusty on EIGRP Path Selection configuration! 🙂 How EIGRP Calculates Metrics, Topology Table, and Feasibility Condition By … Continue reading EIGRP – Metric review, random “offset-list” lab for Path Selection, Feasibility Condition and Variance discussion, and will PBR config override offset-list?

EIGRP – Stub review, default behaviors, basic configuration, Summary-Address and Leak-Maps config, and verification!

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!

EIGRP – Quick review of EIGRP Named Mode, walk through of “Named Mode” EIGRP Configuration with Authentication across the entire EIGRP AS 100 Domain!

Using this Topology I will work across the EIGRP Domain using EIGRP Named Mode, possibly mixing some "Classic" mode EIGRP Routers in there as well, just to see how things are different once I've gotten into a Named Mode groove of configuration. Honestly before running through this lab (when studying for my CCNP R/S) I … Continue reading EIGRP – Quick review of EIGRP Named Mode, walk through of “Named Mode” EIGRP Configuration with Authentication across the entire EIGRP AS 100 Domain!

MPLS – Re-Engineering a 1:1 Customer MPLS L3 VPN Tunnel to serve entire company, tons of ENARSI Topics included in lab, including gotchas for exam day! :)

No PE to CE Adjcancencies, we are getting this entire lab rocking, tonight! 🙂 I don't usually blow away labs as I learn along the way, as I essentially turned all customer into 1:1 mappings across the MPLS, and its just not worth your time reading (you can refer to here for 1:1 Customer mappings). … Continue reading MPLS – Re-Engineering a 1:1 Customer MPLS L3 VPN Tunnel to serve entire company, tons of ENARSI Topics included in lab, including gotchas for exam day! 🙂
