  • Wiley – Wireless Mesh Networks Mar 2009

    By admin | August 6, 2009

    image Written by authors with vast experience in academia and industry, Wireless Mesh Networks provides its readers with a thorough overview and in-depth understanding of the state-of-the-art in wireless mesh networking. It offers guidance on how to develop new ideas to advance this technology, and how to support emerging applications and services. The contents of the book follow the TCP/IP protocol stack, starting from the physical layer. Functionalities and existing protocols and algorithms for each protocol layer are covered in depth. The book is written in an accessible textbook style, and contains supporting materials such as problems and exercises to assist learning.

    Key Features:

    EIGRP – Things to Remember

    By admin | August 4, 2009

    1. The IP header of an EIGRP packet specifies protocol number 88.

    2. To establish neighbor relationship, the neighbors must be in the same IP subnet. While EIGRP supports secondary IP addresses and subnets, EIGRP sources its messages always from the address in the primary subnet, so the IP addresses of neighbors must be in the subnet of the primary subnets. Routers will not form EIGRP neighbors over secondary networks.

    3. Two sides must also match metric weights (K values) in order to form EIGRP neighbor adjacency.

    4. Unlike OSPF, the hello and hold time parameters do not need to match to form EIGRP neighbor relationships.

    OSPF – Things to Remember

    By admin | August 3, 2009

    1. The IP header of an OSPF packet specifies protocol number 89.

    2. To establish OSPF neighbor adjacency, hello/dead timers, MTU (otherwise have to use "ip ospf mtu-ignore") must match. Unique router-id is also required.

    3. Routers in stub area can only be adjacent with the routers in stubs or totally stubby area. Routers in NSSA can only be adjacent with the routers in NSSA or totally NSSA.

    CCNA 640-802 Bible – Compare and Contrast Methods of Routing and Routing

    By admin | August 3, 2009

    1. What are two drawbacks of implementing a link-state routing protocol? (Choose two.)

    A: the sequencing and acknowledgment of link-state packets

    B: the requirement for a hierarchical IP addressing scheme for optimal functionality

    C: the high volume of link-state advertisements in a converged network

    D: the high demand on router resources to run the link-state routing algorithm

    RIPv2 – Things to Remember

    By admin | July 31, 2009

    1. The RIP process operates from UDP port 520.

    2. The metric used by RIP is hop count, with 1 signifying a directly connected network of the advertising router and 16 signifying an unreachable network.

    3. RIP sends periodic updates every 30 seconds minus a small random variable that prevents the updates of neighboring routers from becoming synchronized.

    4. Default route can be advertised in the RIP domain several ways: e.g. (1) static route to 0.0.0.0, with the “redistribute static” command, (2) “default-information originate” command, and (3) “ip default-network” command.
