Discovery 21: Layer 2 and Layer 3 MulticastIn this activity, you will implement and verify the operations of IGMP snooping. You will observe the IGMP packets before and after the receivers announce their presence, and when they leave the multicast group. You will implement IGMP version 2 in this activity. You will observe the multicast flooding on the LAN switch when IGMP snooping is not implemented. Then you will configure IGMP snooping and observe the results that it has on the multicast propagation. |
Discovery 31: PIM-SM Protocol BasicsIn this activity, you will configure and monitor PIM-SM to gain an insight into the sparse mode variant of PIM multicast routing protocol. This activity will allow you to observe the obvious benefits of an explicit model, where the traffic is controlled with periodic control messages. |
Discovery 32: PIM-SM Protocol Mechanics and TimersIn this activity, you will explore the details of PIM-SM, its protocol mechanics, and timers via extensive debugging. |
Discovery 51: PIM Sparse-Dense Mode and Manual RP ConfigurationIn this activity, you will configure, monitor, and troubleshoot PIM sparse-dense mode. You will apply your knowledge of IGMP, PIM-DM, and PIM-SM in a real situation and explore the troubleshooting tools that are needed in simple IP multicast solutions. This lab allows you to experiment with dense mode and sparse mode multicast groups and to introduce some level of control over the groups in the network. Since you will simulate simple deployment of IP multicast, only a manual configuration of RPs will be performed. In this lab, you will configure IGMP filters to allow the receiver to join only certain predefined multicast groups. |
Discovery 52: Configuring Dynamic RP Information DistributionIn this activity, you will configure, test, monitor, and troubleshoot an IP multicast service deployment into your ISP network. You will use PIM-SM while still allowing some DM IP multicast groups in the network. Avoiding the configuration of static RP information, you will choose the Auto-RP solution as a dynamic mechanism for RP announcement. In the lab topology network, you will perform several tests with both sparse mode as well as dense mode groups. For the PIM-SM groups, you will check the RP acceptance and the SPT switchover mechanisms. You will then configure the standard bootstrap mechanism as an alternative to Auto-RP to verify redundant setup of BSR routers and RPs. |
Discovery 53: Bidirectional PIMIn this activity, you will gain insight into the bidirectional PIM mode variant of the multicast routing protocol. Highly scalable, the bidirectional PIM mode is very appropriate for implementation in modern networks. In this activity, you will configure and monitor bidirectional PIM mode basic operations. |
Discovery 54: Source-Specific MulticastIn this activity, you will configure and monitor SSM basic operations. With SSM, the information about which hosts in the network are actively sending multicast traffic is provided by receivers. The receivers provide the information through the source address or through addresses relayed to the first-hop router by IGMPv3 Lite or URL Rendezvous Directory. Source Specific Multicast provides a more advantageous IP multicast service for applications that utilize SSM. |
Discovery 71: Anycast RP, External MP-BGP, and MSDP PeeringIn this activity, you will deploy IP multicast in your network to efficiently distribute your internal information. You will also exchange multicast streams with the ISPs to which you are connected. Both of the ISPs to which you are connected have already deployed IP multicast and established MBGP, MP-BGP, and MSDP peering as well. First, you will deploy the IP multicast with PIM-SM in your AS. You will configure Anycast RP (logical RP) to increase resiliency and distribute the load. After performing a short trial period with an internal multicast source and receiver, you will establish external multicast peerings with both upstream service providers. |
