Multicast routing is not supported on Cisco routers by default. Use the following command to enable multicast routing in global configuration mode: Router(config)#ip multicast-routing
Digital Subscriber Line (DSL) services provide high-speed, low-cost Internet access. They fit nicely between dialup and dedicated access services in terms of both price and speed. DSL service types vary based on which DSL technology is employed. The term xDSL is commonly used to refer to generic DSL services, where x can represent any of a number of different encoding techniques used across the physical line at Layer 1. Table 2-1 lists some of the more common types of DSL tec..
Rate-Limiting and Committed Access Rate
Rate-limiting controls the volume of data entering the network. It is generally deployed on routers that aggregate customer links, and configured parameters may be used as the basis of charging for the link. In particular, if the capacity of the access circuit exceeds the network capacity required by the customer, rate-limiting may restrict a customer's use of the network to the agreed level. Cisco offers three traffic-shaping and policy tools: Generic Traffic S..
RSVP-TE Control-Plane and Forwarding-Plane Components
Now that the usage of RSVP-TE in MPLS-TE has been reviewed, focus turns to the main topic of this chapter: the RSVP-TE control-plane restart. In this chapter, the term FEC refers to an aggregate of data flows defined in terms of filters such as source IP address and other fields in the packet header. Each LSP tunnel is associated with a FEC that specifies which particular set of packets is to be mapped onto the LSP tunnel. RSVP-TE is used to create both resource reservations ..
The finger command is a simple utility that allows you to do the equivalent of a show users command on a remote router. Unix computers generally have a standard finger program that you can run as follows: Freebsd% finger @Router1[Router1] Line User Host(s) Idle Location ..
