I am going to run through all the as brief as possible, so hold onto the seat of your pants. First up, EUI64: Every interface enabled with IPv6 on a Router needs a unique identifier, called an interface identifier, which uses what is called an EUI64 (Extended Unique Identifier). The 64 bits does not refer … Continue reading IPv6: Address types, Prefix-types you must know, Auto-Configuration
Working from Sw1, I want 220.127.116.11 /24 traffic to initialize and be encrypted to the 18.104.22.168 /32 network when traffic hits R2, and vice versa from 22.214.171.124 /32 configured on R1. I want my traffic from this switch specifically destined to network 126.96.36.199 /32 to take the path of R2 - R1 - R5 and … Continue reading Complete guide to Basic IPSec VPN Configuration, explanations of concepts, debugs, and some show commands for tshooting issues!
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!
A very frustrating end to my labbing last night ended with myself not being able to ping from spoke R2 to R3 and likewise, and I called it for the night earlier on, but went back to it as I wanted to see what broke it. So first I turned off the interface running OSPF, … Continue reading Part 3: Troubleshooting the NBMA problem before it drives me bonkers
I told myself I am not going to lab today to avoid CCNP burnout, so I created the above topology which I will be configuring in my next lab session, and did a 'wr er' on all 5 routers and put their base configs (frame relay and IP addressing). It will be very similar to … Continue reading Lab plan for EIGRP / RIPv2 / OSPF Redistribution and more!
The following is a quick logical topology I whipped up in Paint, leaving out the Loopback info as that would make for a lot of micro-text, this is what will be configured once we go through some Redistribution and Stub Area configuration: To inject routes into OSPF, which then makes the router an ASBR, … Continue reading OSPF Redistribution, Stubs, Total Stubs, NSSAs
This again will be bullet point facts on Fundamental OSPF concepts, with a taste into Advanced topics, but I will save the Advanced topics for their posts (such as LSA's, Stub Areas, IPv6, etc). This will get me up to speed in Chris Bryants Book so I am where I am at on his video … Continue reading OSPF Fundamentals in a can
Instead of labbing my remaining topics for EIGRP from my Chris Bryant video series, as I am too mentally tired to lab into all hours of the night, so instead I started reading Chapter 1 of ROUTE Simplified. I must say, given the size and weight of this book, it has to be by far … Continue reading ROUTE Simplified – Overview stuff, ODR
