Multicast Overview

This manual covers the configuration of HPE FlexNetwork MSR Router Series devices with Comware 7 software. It provides detailed information on multicast concepts, protocols, and configuration steps.

Key Sections:

  • Multicast Overview: Explains the fundamentals of multicast, including unicast, broadcast, and multicast transmission techniques, multicast features, benefits, applications, models, architecture, and addresses.
  • IGMP Snooping: Details how IGMP snooping works on Layer 2 devices to constrain multicast traffic, including port configurations and policies.
  • Multicast Routing and Forwarding: Covers configuring IP multicast routing, static routes, load splitting, and forwarding boundaries.
  • IGMP: Explains IGMP versions, SSM mapping, proxying, and configuration tasks.
  • PIM: Describes PIM-DM, PIM-SM, BIDIR-PIM, PIM-SSM, and their configurations.
  • MSDP: Covers Multicast Source Discovery Protocol for inter-domain multicast.
  • Multicast VPNs: Explains multicast application within VPNs.
  • MLD Snooping: Details MLD snooping for IPv6 multicast traffic.
  • IPv6 Multicast Routing and Forwarding: Covers IPv6 multicast routing configurations.
  • MLD: Explains MLD versions and configurations for IPv6.
  • IPv6 PIM: Covers IPv6 PIM-DM, PIM-SM, BIDIR-PIM, and PIM-SSM configurations.
  • Troubleshooting: Provides solutions for common multicast issues across various protocols.

Troubleshooting and error codes

Symptom Solution
A multicast distribution tree cannot be correctly built
  • Verify IPv6 unicast route to the multicast source or RP.
  • Verify IPv6 PIM information on each interface.
  • Verify RPF neighbor is an IPv6 PIM neighbor.
  • Verify IPv6 PIM and MLD are enabled on interfaces connected to sources/receivers.
  • Verify same IPv6 PIM mode enabled on RPF interface and neighbor's interface.
  • Verify same IPv6 PIM mode on all routers; verify BSR and C-RPs for PIM-SM.
  • Contact HPE Support if problems persist.
IPv6 multicast data is abnormally terminated on an intermediate router
  • Verify IPv6 multicast forwarding boundary settings and adjust if necessary.
  • Verify IPv6 multicast source policy and adjust ACL rules if needed.
  • Contact HPE Support if problems persist.
An RP cannot join an SPT in IPv6 PIM-SM
  • Verify IPv6 unicast route to the RP on each router.
  • Verify dynamic RP information is consistent on all routers.
  • Verify static RPs are configured consistently on all routers.
  • Contact HPE Support if problems persist.
An RPT cannot be built or IPv6 multicast source registration fails in IPv6 PIM-SM
  • Verify IPv6 unicast routes to C-RPs and BSR, and route between C-RP and BSR.
  • Verify BSR information exists on each router.
  • Verify RP information is correct on each router.
  • Verify IPv6 PIM neighboring relationship is established among routers.
  • Contact HPE Support if problems persist.
