It's been a few years but I've finally gotten back to setting up a new website for wr-mem. This site is a work in progress and I will try to update it regularly as I go and learn new things. I'm currently building a home LAB environment which should provide me with a lot of potential content. I also use this site to record issues that I come across or new content I learn and Lab in the hopes that it will help others as they learn and explore. 

Once again, configuring a new ASA Firewall and I've gone to SSH into it using SecureCRT and found I can't. When I attempted to SSH, I received the following error. 

Key exchange failed.
No compatible key-exchange method. The server supports these methods: diffie-hellman-group14-sha256

I started reading about IPv6 because well it's about time and given I run it at home I probably should so I started reading the Cisco IPv6 Fundamentals book. And I guess let's start from the the basics of IPv6 addresses. 

Anything I lab will go here

This page is used to show specific examples of packet captures for things like OSPF neighbour adjacency exchange, or EIGRP neighbour adjacencies etc. I find these very helpful to go through when learning about various networking technologies like routing protocols or learning about STP messages etc. 

To start with, this is a capture of an EIGRP neighbour relationship forming between two adjacent routers within the EIGRP AS 100. You can click on the screeshot to download the actual wireshark PCAP file to inspect the packets further.
