Pick up where certification exams leave off. With this practical, in-depth guide to the entire network infrastructure, you’ll learn how to deal with real Cisco networks, rather than the hypothetical situations presented on exams like the CCNA. Network Warrior takes you step by step through the world of routers, switches, firewalls, and other technologies based on the author's extensive field experience. You'll find new content for MPLS, IPv6, VoIP, and wireless in this completely revised second edition, along with examples of Cisco Nexus 5000 and 7000 switches throughout.

Topics include:

  • An in-depth view of routers and routing
  • Switching, using Cisco Catalyst and Nexus switches as examples
  • SOHO VoIP and SOHO wireless access point design and configuration
  • Introduction to IPv6 with configuration examples
  • Telecom technologies in the data-networking world, including T1, DS3, frame relay, and MPLS
  • Security, firewall theory, and configuration, as well as ACL and authentication
  • Quality of Service (QoS), with an emphasis on low-latency queuing (LLQ)
  • IP address allocation, Network Time Protocol (NTP), and device failures

Each interface must be configured individually with the switchport access command.

Trunk mode (on,off,desirable,auto,nonegotiate) Trunk type (isl,dot1q,dot10,lane,negotiate) VLAN number The mode on indicates that the port has been hardcoded to be a trunk, and the mode off indicates that the port will never be a trunk. The modes desirable and auto are both dynamic and refer to the method with which DTP will operate on the port. desir able indicates that the port will initiate negotiations and try to make the link a trunk. auto indicates that the port will listen.

That the networks behind Routers A and C in Figure 10-9 are different, but from RIP’s point of view, you would be wrong. Technically, the networks behind Routers A and C are the same. They are both part of the 10.0.0.0/8 network. The routers are connected to different subnets within the 10.0.0.0/8 network, which is why RIP has a problem with the design. The only other type of network that RIP understands is a host network. RIP can advertise a route for a /32 or 255.255.255.255 network. Because.

Unless you’re working at a tier-1 service provider, where else could you get to poke around with a BGP router that has 20 neighbors, 191,898 prefixes, and 3,666,117 paths? I have a pretty cool lab, but I can’t compete with that! Here is the output from an actual route server: route-server>sho ip bgp summary BGP router identifier 10.1.2.5, local AS number 65000 BGP table version is 208750, main routing table version 208750 191680 network entries using 19359680 bytes of memory 3641563 path entries.

On Router A, but reverse the source and destination: Router-D(config)#int tu 0 23:45:13: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to down Router-D(config-if)# ip address 172.16.0.2 255.255.255.0 Router-D(config-if)# tunnel source lo 0 Router-D(config-if)# tunnel destination 10.100.100.100 Router-D(config-if)# 23:47:06: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to up Now we have a live link between these routers, which appear to be.
