Sample text

Routers, on the other hand, do not block redundant network paths; instead, they rely on routing protocols in order to use the optimum path and to prevent loops. A switched network is said to be converged when all ports are in a forwarding or blocking state, while a routed network is said to be converged when all routers have the same view of the network. Depending on the size of the switched network, convergence might take a very long time. Routers have the advantage of using advanced routing protocols, such as OSPF, that maintain a topology of the entire network, allowing for rapid convergence.

TCAM Ignores Wildcard Fields In the diagram above, the packet lookup is based on the address 10100011010100. Even though TCAM has the ability to ignore certain fields, the longest match lookup is still performed for CEF and ACLs. Additionally, because all entries are checked in parallel, this results in the same performance regardless of the number of entries. NOTE: You are not required to demonstrate detailed knowledge of CAM or TCAM architecture as part of the SWITCH exam requirements. Segmenting the LAN Using Bridges and Switches When designing the networks of yesteryear, network engineers had only a limited number of hardware options when purchasing technology for their campus networks.

1-1. Switches Learn MAC Address of Connected Devices Because they initially have no idea where the destination device is, switches broadcast the received frame out of every port, except for the port on which the frame was received. This is illustrated in Figure 1-2 below: Fig. 1-2. Switches Send Broadcasts until They Build a MAC Address Table After the switch has flooded the broadcast packet, it will wait for a device to respond. When the intended destination device responds to the broadcast packet, the switch will note the port the response was received on and place that address into the forwarding table, which is also called the MAC address table.
