First and foremost, I think saying that taking the route and failing the first time should be actually fairly standard, unless you use brain dumps or study / lab from CCIE level material (and even then...). That being said, lets get into my thoughts: It has the same old Cisco gotchas, so always compare the … Continue reading Failed first Route attempt, not due to content here being incorrect, but some Cisco gotchas and the timer beat me up!
We have a lot to accomplish, but first since I did a "wr er" like a nerd I have to reconfigure all the IP addresses again (as you see in the Topology I changed them to make them a bit more intuitive). One thing I wanted to point out while configuring this whole lab (and … Continue reading Part 1: Configuration of this new Topology in IPv6
To note I used the same color I have previously for IPSec VPN tunnels, however that color is more just one of the few colors not reserved for protocols (as I generally use blue for OSPF, red for RIP, and orange for EIGRP), so this time green is for VRF-Lite. So I wanted to pull … Continue reading VRF-Lite: Complete configuration and explanation of behaviors, OSPF and EIGRP demonstration and how they work (or why the don’t work)
I took a quick moment to post before this, advising not to study or lab tired, cause as can be seen towards the end of my Part 4 of this lab I am just tired and swinging at air. Anyway, we now have R1 and R3 both acting as ASBR's, with R1 doing 2-way route-tagged … Continue reading Part 5: Turning “IP Routing” on for Layer 3 SW1, Policy / Local Policy Routing, found sub-optimal routing due to AD! (Will be 6th lab to troubleshoot)
(Added interface #'s to the Topology as we increase working with both IP's and interfaces) I wanted to touch this quick before moving on to policy routing, whether Distribute-Lists can block certain networks from a Summary Route, or if it's possibly at all. So I'll run through it quick here to move on: Distribute-List … Continue reading Part 4: The right ACL for the right job (Distribute-List vs Route-Map), Configuring 3-way Route Redistribution with a lot of failures but final success!!!
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!
Due to the summer getting busy, and posts getting sporadic to the point that I was not retaining the material / labbing, I decided to take a short break which turned into a 6 month break. A word to the wise, do not take time off from studying unless you need to (vacation, family emergency, … Continue reading Break from studying turned into 6 months in the blink of an eye!
