8 C1640M-B (3/06) – Sparse Mode is most useful in the following instances: • There are few receivers in a group. Switches send multicast traffic only to the devices that request it. • Senders and receivers are separated by Local Area Network (LAN) links. • The type of traffic is intermittent. PIM-SM is optimized for environments where the[...]

C1640M-B (3/06) 9 Understanding the Endura Network Structure The primary structure of an Endura network topology is organized into functional entities, which are called “blocks.” Grouping the functional entities into individual blocks provide the following benefits: • Blocks control and isolate traffic. • Block design can be physical or l[...]

C1640M-B (3/06) 11 USING TTL TO CONTROL NETWORK T RAFFIC IN BROADCAST DOMAINS In the Endura network, TTL is used to set the maximum amount of router hops that a packet is allowed to propagate through the network before the packet is discarded. Using TTL provides an effective method to determine how many broadcast domains a given packet can traverse[...]

12 C1640M-B (3/06) ENDURA B BLOCK The Endura B Block generally determines the bandwidth requirements for the network.
