NON-ECMP PIM FRR Based on Multicast Static Route

NON-ECMP PIM FRR Based on Multicast Static Route

Service Overview

In a NON-ECMP network, the IGP LFA FRR function may fail to calculate unicast routes. To avoid multicast service failure, configure static main and backup routes to establish main and backup links.

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 4-48.

Feature Deployment

PIM FRR is used to transmit and protect IP multicast services. The process consists of the following stages:
  • Configure FRR based on multicast static routes.

    Configure FRR based on multicast static routes on each node of the circle, so that each node can generate main and backup unicast routes.

  • Configure PIM FRR.

    PIM FRR is configured on each node of the circle. 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 nodes rapidly switch to the backup link to protect the multicast traffic.
