VLANs and spanning tree
Cisco Hands On Training Podcast - January 31, 2009 17:33 - Video ★★★★ - 72 ratingsVLANs are a feature of ethernet switches which makes them act like multiple "virtual switches". Each VLAN is a separate broadcast domain and could be configured with a separate subnet. That way could could have separate subnets for separate purposes (IT, accounting, network management) on one p...
How ARP and Ethernet Work
Cisco Hands On Training Podcast - January 25, 2009 05:22 - Video ★★★★ - 72 ratingsSo far we've talked about how IPv4 encodes data into a packet, and how routers learn which direction to forward those IPv4 packets based on the destination IP address and the route table. But in the end, routers and hosts need to encode the IPv4 packet onto a physical medium. Examples of physic...
BGP route selection with MEDs
Cisco Hands On Training Podcast - May 29, 2008 05:42 - Video ★★★★ - 72 ratingsIn BGP, MED stands for Multi Exit Discriminator. It is a well-known optional attribute which allows one autonomous system to inject it's IGP route metrics into its BGP advertisements to another BGP autonomous system. This allows the second autonomous system to make intelligent routing decisions...
BGP route filtering

Introduction to BGP theory
Cisco Hands On Training Podcast - March 15, 2008 05:46 - Video ★★★★ - 72 ratingsAn introduction to BGP theory.
OSPF route filtering and area border routers
Cisco Hands On Training Podcast - October 21, 2007 05:45 - Video ★★★★ - 72 ratingsOSPF routes should be filtered or summarized at area border routers.
OSPF distribute-list problems
Cisco Hands On Training Podcast - October 07, 2007 05:41 - Video ★★★★ - 72 ratingsOSPF's fundamental design is that all routers in an area have the same exact view of the network topology. This is fundamentally incompatible with filtering routes within an area. As a result OSPF distribute lists do not have the same effect as RIP distribute lists. In fact, using distribute-l...
Totally stubby and not-so-stubby OSPF areas
Cisco Hands On Training Podcast - September 30, 2007 05:39 - Video ★★★★ - 72 ratingsOSPF totally stubby areas and not-so-stubby areas are ways to improve OSPF scalability. But they can be very confusing.
OSPF stub areas and neighbor synchronization
Cisco Hands On Training Podcast - September 23, 2007 05:35 - Video ★★★★ - 72 ratingsWe cover OSPF stub areas and neighbor synchronization.
OSPF Redistribution
Cisco Hands On Training Podcast - July 31, 2007 05:33 - Video ★★★★ - 72 ratingsWe redistribute from RIPv2 into OSPF and introduce autonomous system boundry summary LSAs and external summary LSAs.
OSPF Areas and Network Summary LSA's
Cisco Hands On Training Podcast - July 16, 2007 05:31 - Video ★★★★ - 72 ratingsWe introduce multiple OSPF areas and network summary LSA's.
Introduction to OSPF
Cisco Hands On Training Podcast - July 01, 2007 05:29 - Video ★★★★ - 72 ratingsWe show a single area OSPF network and go into router and network link state advertisements (LSA's) in detail.
Shortest Path First Algorithm
Cisco Hands On Training Podcast - June 04, 2007 05:26 - Video ★★★★ - 72 ratingsA brief tutorial on Dijkstra's Shortest Path First Algorithm. This algorithm is used by most link state routing protocols, including OSPF and IS-IS.
RIPv2
Cisco Hands On Training Podcast - September 22, 2006 05:25 - Video ★★★★ - 72 ratingsRIP version 2 includes subnet information in the route advertisement. It also improves efficiency by multicasting to RIPv2 routers instead of broadcasting to all hosts.
Migrating from RIPv1 to IGRP via route redistribution
Cisco Hands On Training Podcast - July 25, 2006 05:21 - Video ★★★★ - 72 ratingsIf you run two different routing protocols in two different parts of your network, you need to redistribute routes between the two routing protocols. This session is an introduction to route redistribution by example. In production you must be cautious about route redistribution because the rou...
Migrating from RIPv1 to IGRP via "ships in the night" routing
Cisco Hands On Training Podcast - July 10, 2006 05:17 - Video ★★★★ - 72 ratings"Ships in the night" routing refers to two routing protocols which do not interact with each other. We can migrate from one routing protocol to a more believable one by simply turning on the new protocol then turning off the old protocol. Bug be careful to turn the new protocol on in the entire...
IGRP: Interior Gateway Routing Protocol
Cisco Hands On Training Podcast - June 29, 2006 05:14 - Video ★★★★ - 72 ratingsIGRP is a Cisco-proprietary routing protocol. It is a classful distance vector protocol with a metric based on bandwidth and delay. This is superior to RIP, whose metric is based on hop-count. IGRP's classfulness makes it a bad choice for new deployments, but its advanced metric is worth study.
RIPv1 distribute lists and offset-lists
Cisco Hands On Training Podcast - June 21, 2006 05:12 - Video ★★★★ - 72 ratingsRIP distribute lists deny specific route advertisements. RIP offset-lists increase the metric (hopcount) for specific route advertisements.
Problems with RIP Version 1
Cisco Hands On Training Podcast - June 19, 2006 05:08 - Video ★★★★ - 72 ratingsRIP version 1 route advertisements do not include a field for the netmask. This means receiving routers have to gess the netmask based on whatever information they have available. That includes the "natural" netmask of that classful network. That also includes the receiving routers own configu...
RIP Version 1
Cisco Hands On Training Podcast - June 17, 2006 05:05 - Video ★★★★ - 72 ratingsRIP version 1 is a classful routing protocol. We cover the RIP packet format and configuration. We see examples of split horizon and triggered updates using the RIP debug commands.
Static routing and introduction to CEF
Cisco Hands On Training Podcast - June 13, 2006 05:04 - Video ★★★★ - 72 ratingsRouting protocols (and static routing) update the route table. The route table is used to forward packets. Cisco Express Forwarding (CEF) is a special route table optimized to forward packets more efficiently.
Serial and ethernet point-to-point links
Cisco Hands On Training Podcast - June 11, 2006 04:59 - Video ★★★★ - 72 ratingsWe cable and configure ethernet and synchronous serial point-to-point links. In the next session these will be the "legs" of our triangle.
Classful IP addressing
Cisco Hands On Training Podcast - June 08, 2006 04:54 - Video ★★★★ - 72 ratingsRouters route packets based on the destination IP address: a 32-bit number included in the header of every IP packet. Historically, "large" sites were allocated IP address blocks starting with 0 (binary). Medium sites were allocated address blocks starting with the bits 10. "Small" sites were ...
Cisco 2500 password recovery
Cisco Hands On Training Podcast - June 03, 2006 04:42 - Video ★★★★ - 72 ratingsEvery network engineer needs to be able to deal with a router with an unknown password. Whether you are taking over a site where the previous engineer was "hit by a bus", or scrounging routers from the storage closet, good network engineers can deal with routers with unknown passwords.
