Route Summurization Calculator
This is a route summurization calculator. Please enter some route values seperated by spaces (such as 1.2.3.4 1.2.3.5), or if it is a range enter between "-" (such as 172.16.128.0-172.16.159.255).Free Cisco Lab
In this Free Cisco Lab scenario you will use Packet Tracer to configure 10 routers to use IPV6 , enabling IPV6 on each router, and assign each router an IPV6 address. You will then configure RIP , EIGRP, and OSPF as shown in the provided network diagram. You will then redistribute the RIP, OSPF and EIGRP routing protocols over the network. Finally you will use Ping, Debug, and Show commands to verify the operation and connectivity of the network. Voice over IP ( VoIP ) has become a very important part of the network engineer’s job in today’s new IT department. Cisco has added a new certification to their CCNA program (CCNA Voice) to prepare new Cisco engineers for this exciting technology.
Configuring and Troubleshooting Ethernet 10/100/1000Mb Half/Full Duplex Auto-Negotiation - Cisco Systems
This document provides basic guidelines to isolate and resolve many common Ethernet auto-negotiation issues. This document provides a general description of auto-negotiation, and explains the procedure to configure and verify auto-negotiation on Catalyst switches that run the Catalyst OS (CatOS) system software. This document also shows an example of why the most common duplex-mismatch error occurs, and describes how to configure and verify auto-negotiation on Catalyst switches that run Cisco IOS ® System Software. Note: The new Catalyst switches/modules, such as the Catalyst 6500/6000, 4500/4000, 3550, and 2950, support 10/100/1000 Mbps negotiated Ethernet interfaces or ports.
