In this demo, we cover these features in order for you to become familiar with the basics of IP multicast on the Cisco IOS-XR. Download Ebook Configuring Multicast Routing Cisco Configuring IP Multicast Routing - Cisco Cisco recommends that you use Protocol Independent Multicast (PIM) sparse mode, particularly Auto-RP, where possible and especially for new deployments. IGMP Proxy allows hosts in a UDLR (Unidirectional Link Routing) topology that are not directly connected to a downstream router to join a multicast group from an upstream router by using a back channel. The ip nhrp map multicast dynamic command enables the forwarding of multicast traffic across the tunnel to dynamic spokes. These conect to a Core Cisco 3850 L3 Switch running IP Base and this conects to the WAN. In most cases, DMVPN is accompanied by a routing protocol to send and receive dynamic updates about the private networks. Let's enable PIM sparse mode on all interfaces: R1 (config)#interface GigabitEthernet 0/1 R1 (config-if)#ip pim sparse-mode. Select the Enable Multicast Routing check box. The main command is ip pim sparse-mode. In the case of sparse mode, a Rendezvous Point (RP) is to be configured. Multicast Overlay Routing Overview. However, if dense mode is desired, configure the global command ip multicast-routing and the interface Download Ebook Configuring Multicast Routing Cisco Configuring IP Multicast Routing - Cisco Cisco recommends that you use Protocol Independent Multicast (PIM) sparse mode, particularly Auto-RP, where possible and especially for new deployments. A couple of days ago I was looking for information about SDM Templates on Cisco online documentation and to my biggest surprise I saw the following command sdm prefer routing-lanbase . CAPWAP multicast packets are forwarded using the management interface. As enterprises extend the reach of their multicast applications, service providers can accommodate them over their Multiprotocol Label Switching (MPLS) core network. IP multicasting is a more efficient way to use network resources, especially for ba Configuring Multicast VPN. If the value is changed from a number such as 10 to 0, all current caches is cleared. Don't forget to enable multicast routing on R2 and R3 because they'll have to forward the multicast packets: R2 & R3: (config)#ip multicast-routing. Configure Multicast Routing. 6. After performing these tasks, the device can then forward multicast packets and can populate its multicast routing table. There are hosts that conect to the Cisco 2960s which partake in multicast and will do across the WAN. For Configuration Guides for the latest releases, see Configuration Guides. The following example shows a device running Cisco IOS Software or Cisco IOS XE Software with IPv6 multicast routing enabled: The device performs multicast routing in two modes: . The Multicast VPN (MVPN) feature provides the ability to support multicast over a Layer 3 VPN. OSPF has been pre-configured so that all networks are reachable. The Multicast Setup dialog box appears. The focus of this lab is on the multicast part of the . Verification. This is to discover and form adjacencies with PIM Neighbors. The device performs multicast routing in two modes: . Acces PDF Configuring Multicast Routing Cisco info.ghcma.vic.gov.au learn how traffic starts out across a network Static routing—Build router routing tables and understand how forwarding decisions are made and processed Spanning Tree Protocol—Learn how this protocol is an integral part of every network containing switches Virtual Local Area On Cisco Nexus devices, you'll need to enable the PIM feature with the command "feature pim" before any of the other commands become available. The Multicast Service Reflection feature is available in Cisco IOS Release 12.4 (4)T on software-based nondistributed forwarding platforms, up to and including the Cisco 7200 series routers, as well as Cisco Catalyst 6500 series switches providing forwarding in hardware in Cisco IOS Release 12.2 (33)SXI4. More experience of Cisco 2960G enable routing from Cisco fans: Yeah, indeed, now, the Cisco 2960 can do routing, and surprisingly it works out pretty well. To participate in IP multicasting, the multicast hosts, routers, and multilayer switch must have IGMP operating. R3 will now perform a RPF check for both multicast packets. Because IPv4 multicast forwarding is enabled by default, use the no form of the ip mfib command to disable IPv4 multicast forwarding. Set up an RP - "ip pim rp x.y.z.q" If you don't have an RP in your network just set up a loopback interface on your switch and use its address. The Multicast Routing section will now be available. There are a few basic configuration tasks that need to be performed on Cisco IOS routers in order to enable multicast on the network. This volume presents an examination of exterior routing protocols (EGP and BGP) and advanced IP routing issues such as multicast routing, quality of service routing, Ipv6, and . This chapter describes how to configure IP multicast routing on the Catalyst 3750 Metro switch. Cisco SD-WAN documentation is now accessible via the Cisco Product Support portal. We will configure this network so that R1 is the receiver, R4 is the source and R2 will become our multicast stub router. In the Multicast Routing Configuration Menu, select 1. And the strangest thing now is that i just put all settings back to default which is IGMP enabled in switch settings and Multicast Routing disabled in the Routing and DCHP. This can be a multicast routing-enabled interface or custom IP for a third-party RP. Select the interfaces that require multicast routing. Instead of fully participating in multicast routing, the FWSM forwards IGMP messages to an upstream multicast router, which sets up delivery of the multicast data.

In this example, we've done three things: First, "the ip multicast-routing command" enables multicast routing, which is disabled by default because most networks don't use it. In our scenario, we use a default route towards the ISP router so our unicast routing doesn't match our multicast routing. IP multicasting is a more efficient way to use network resources, especially for bandwidth-intensive services such as audio and video. The multicast-enabled network receives the CAPWAP multicast from the management interface and forwards the packet to the APs through the multicast overlay. Cisco IOS XR Fundamentals is an indispensable resource for designing, implementing, troubleshooting, administering, or selling networks containing Cisco IOS XR-supported routers. 6. R1,R2,R3,R4: (config)#router ospf 1 (config-router)#network 0.0.0.0 255.255.255.255 area 0. Use this command on your switch to enable multicast: ip multicast-routing.

Enable multicast routing on the router in global configuration mode. This relieves the WLC of the burden of replication. And make sure to enable PIM on the interfaces facing the source (R1), the receiver (R4) and between R2/R3: To use the IP multicast routing feature on the device, the device or active device must be running the IP Services feature set. IGMP Version 1 (IGMPv1) primarily uses a query-response model that enables the multicast router and multilayer switch to find which multicast groups are active (have one or more hosts interested in a multicast group) on the local subnet. We can fix this with a static mroute for our source: R2 (config)#ip mroute 192.168.1. Click Add a rendezvous point . The same RP cannot be used for both bidirectional and sparse mode groups. VLAN: The VLAN this routed interface is on. Configuring IP Multicast Routing This chapter describes how to configure IP multicast routing on the Cisco ME 3800X and ME 3600X switch. However i have doubt about that how ospf client or any OSPF running router joins the multicast group (224.0.0.5 or 6) and if all the router by default enable multicast routing for OSPF or any other routing protocol multicast ? I am sorry to disappoint you. Next configuration item is to enter the VLAN interface and configure the sparse mode: interface vlan vlan-id ip pim sparse-mode. Multicast routing and its associated protocols. Configuring Multicast Overlay Routing Last updated; Save as PDF No headers.
