7). Cisco CCNA Exam Tutorial: Configuring Standard Access Lists By : Chris Bryant, CCIE #12933 Access Control Lists (ACLs) allow a router to permit or deny packets based on a variety of criteria. The ACL is configured in global mode, but is applied at the interface level. An ACL does not take effect until it is expressly applied to an interface with the ip access-group command. Packets can be filtered as they enter or exit an interface. If a packet enters or exits an interface with an ACL applied, the packet is compared against the criteria of the ACL.
8). Cisco CCNP / BSCI Exam Tutorial: Using The OSPF Command “Area Range” By : Chris Bryant, CCIE #12933 Your BSCI and CCNP exam success depends on knowing the details, and one such detail is knowing the proper way to summarize routes in OSPF. Route summarization is not just a test of your binary conversion abilities, but knowing where and when to summarize routes.

Or you decide to go to the gym, or play a game, or do anything else except go see the client. Even if you weren't going to get fired for not showing up, it's certainly unfair to the client.
5). CCNP Certification / BSCI Exam Tutorial: The BGP Neighbor Process By : Chris Bryant, CCIE #12933 Like TCP, BGP is connection-oriented. An underlying connection between two BGP speakers is established before any routing information is exchanged. This connection takes place on TCP port 179. As with EIGRP and OSPF, keepalive messages are sent out by the BGP speakers in order to keep this relationship alive. Once the connection is established, the BGP speakers exchange routes and synchronize their tables.
6). CCNP Certification / BCMSN Exam Tutorial: Server Load Balancing (SLB) By : Chris Bryant, CCIE #12933 When you're working on your BCMSN exam on your way to CCNP certification, you'll read at length about how Cisco routers and multilayer switches can work to provide router redundancy - but there's another helpful service, Server Load Balancing, that does the same for servers.
