This may be brief as I am dealing with a mixture of back pain / medicine for it, so I am going to try to focus long enough to apply Authentication in a mixture of ways, across both my NBMA network and my Total Stub / NSSA Areas, this can be done two ways with … Continue reading OSPF Authentication across multiple Area and Stub / NSSA networks
So I actually did not wr mem any routers from my previous lab where Area 15 and 34 were turned into virtual-links, so we are back to the NSSA for Area 15 and the Total Stub on Area 34. My goal is to figure out if and where static IP's can be assigned to route … Continue reading Using Static Routes / Redistribution to overcome Stub to Stub communication
Between the holidays and throwing my back out worse than I think I ever have had kept me from moving forward with subjects, but I am determined to get back to where I left off months before the summer by the New Year if life doesn't happen again by then. That being said, I am … Continue reading OSPF Stub troubleshooting, Virtual-Links (solved on next post)
After coming back from a weekend of being sick, I'm going to perform what has already been covered in previous posts so I may not go crazy with output from configs, however I do want to document any road blocks I struggle with or unexpected network behaviors. I did some reading of my original notes … Continue reading Redistribution, Stub Areas, NSSA’s, Summarization, Metric changing
I was going to only clean off my dry erase board for drawing out my topologies on the fly, and do a write erase on all routers for when I re-familiarized myself with OSPF, however like an IT nerd on a Friday night I decided to setup at least the NBMA routers R1 R2 and … Continue reading OSPF Basics came back almost instantly today, stubbys tomorrow, redistribution Sunday and I am caught up
I wanted to quickly attack a few points tonight as I am mentally dead between working and studying simultaneously. One thing I found amazingly interesting when familiarizing myself with debug output for "debug eigrp packets" especially with passive interfaces, is that the loopback interface is creating as much if not unneeded output than the Fa0/0 … Continue reading Finished EIGRP refresher, found good info for passive-int via debug eigrp pack, quick stub routing confusion
Above is the following topology I have created, all interfaces on the NBMA are on the 18.104.22.168 /24 subnet and the LAN section will be 22.214.171.124 /24 with all interfaces aside from loopbacks having the router # as the 4th octet IP address. Upon going through even basic EIGRP setup videos over an NMBA network, … Continue reading Some things I know I will forget again, lots of bullet points, like the ‘in a can’ posts
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!
