This module maps to the following ICND1 syllabus requirements: Configure and verify Layer 2 protocols ---- --------- ------------------------------- Figure 6.2 below illustrates the valid combinations that will result in the successful establishment of a trunk link between two neighboring switches – one using DTP and the other statically configured as a trunk port: Learn how to apply basic security settings to a Cisco switch. R1(config-router)#maximum-paths ? I suggest that you learn to configure all three types and test them by logging in to the router. You will have different choices depending upon your platform and IOS: The port security feature is designed to protect the switched LAN from two primary methods of attack. These attack methods, which will be described in the following sections, are: 　remove remove VLANs from the current list Switch1(config-if)#switchport trunk allowed vlan 7-12 Copyright (c) 1986-2005 by Cisco Systems, Inc. Compiled Wed 12-Oct-05 22:05 by pt_team Time remaining: 90 seconds 5.At this point, if you ping from one PC to another, it should fail. This is because one side is in VLAN 1 and the other is in VLAN 2. ACL Rule 7 – You can reuse the same ACL. R1#show ipv6 route static CDP is enabled by default on Cisco devices. LLDP is disabled. For this lab I simply connected two 2960 switches using a crossover cable on port G0/1. Passive interfaces are usually able to receive routing updates or Hello packets but are not allowed to send any kind of routing protocol information outbound. Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds: Switch(config)#interface FastEthernet0/1 Switch(config-if)#switchport port-security access Set trunking mode to ACCESS unconditionally 3.4.d Single vs dual-homed [ICND2] Walkthrough If you check the routing table, you will see the administrative distance for RIP and the output we covered earlier: Verifying the Correct Path Selection Pinging 192.168.1.1 with 32 bytes of data: Violation Mode : Shutdown System Description: Cisco routers use the administrative distance, the routing protocol metric, and the prefix length to determine which routes will actually be placed into the routing table, which allows the router to build the routing table. The routing table is built via the following general steps: R1#show ip protocols Routing Protocol is “rip” advertisement version: 2 Fa0/2 on 802.1q trunking 1 Management Addresses - not advertised Auto Negotiation - supported, enabled Learn how to configure DTP settings on Cisco switches.

For example,350-801 clcor study guide, RIP might consider a path that is only two hops long as the most optimal path to a destination network, even though the links were 64Kbps links, while advanced protocols such as OSPF and EIGRP might determine that the most optimal path to that same destination is the one traversing four routers but using 10Gbps links. Pinging 192.168.1.1 with 32 bytes of data: RouterA(config)#ip route network prefix mask {address | interface} [distance] Switchport: Enabled Administrative Mode: static access Operational Mode: static access Manual (Static) Trunk Configuration 4.On the right router, turn LLDP off the entire device. Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP U - Per-user Static route, M - MIPv6 Your choices as a network administrator are to use dynamic routing protocols on your network or static routing, which is where you manually add each route for your network onto each router. A routing protocol allows a router to learn dynamically how to reach other networks. A routing protocol also allows the router to exchange learned network information with other routers or hosts. Routing protocols may be used for connecting interior (internal) campus networks, as well as for connecting different enterprises or routing domains. Therefore, in addition to understanding the intricacies of routing protocols, it is also important to have a solid understanding of when and in what situation one routing protocol would be used versus another.
