Service Overview

There is an increasing diversity of multicast services, such as IPTV, multimedia conference, and massively multiplayer online role-playing games (MMORPGs), and multimedia conferences. To bear these services, the service providers' networks have to meet the following requirements:
  • Forward multicast traffic even during traffic congestion.
  • Rapidly detect network faults and switches traffic to a standby link.

Networking Description

PIM FRR function deployed on the user-access devices helps the network prevent multicast traffic congestion and maintain reliability. PIM FRR is used on the IPTV service network shown inFigure 4-47.

Feature Deployment

PIM FRR is used to transmit and protect IP multicast services. The process consists of the following stages:
  • Deploy IGP LFA FRR.

    Deploy ISIS LFA FRR or OSPF LFA FRR to the protection nodes, such as DeviceA, so that the nodes can generate main and backup unicast routes.

  • Configure PIM FRR.

    PIM FRR is configured on protection nodes, such as DeviceA. When a user joins in, a main multicast forwarding entry and a backup multicast forwarding entry are generated. If the network operates normally, the protection nodes only receive the multicast traffic from main link and drop the traffic from backup link. If the main link fails, the protection node rapidly switch to the backup link to protect the multicast traffic.
