Study Update # 2

Well after studying OSPF earlier today I took a break and ran some errands along with hanging with family. I finished up the night with reviewing access-list information from the Cisco learning Network. I began by going through some of the Cisco web video but I decided to lab up a quick network using Packet Tracer first. I set up two Class B networks using the default mask along with a gateway to the internet using a Class A address. I used two routers in Point-to-Point configuration which had one router being the gateway to the internet (Class A network). I practiced some commands on the other router such as turning auto-summarization off and setting a default-network to reach the Class A internet. Last but not least I practiced creating an extended ACL that would prevent a particular host from sending SMTP packets to the internet but could allow all other traffic. All went well so I decided to finish up the Cisco web videos and now it's time for bed!
