Option: Configuring PIM Sparse Mode Graceful Restart for a Layer 3 VPN

Graceful restart permits a routing platform to continue forwarding multicast traffic to neighbors while the routing protocol process restarts. To enable graceful restart for PIM sparse mode in a Layer 3 VPN, include the graceful-restart statement at both the [edit routing-options] and [edit routing-instances instance-name routing-options] hierarchy levels. To disable graceful restart in a Layer 3 VPN, include the disable statement at the [edit routing-instances instance-name protocols pim graceful-restart] hierarchy level.

[edit]routing-options {graceful-restart {disable;restart-duration seconds;}}routing-instances {instance-name {.....protocols {pim {graceful-restart {disable;restart-duration seconds;}}}routing-options {graceful-restart {disable;restart-duration seconds;}}}}

For more information about PIM sparse mode graceful restart in a Layer 3 VPN, see the JUNOS High Availability Configuration Guide or the JUNOS Multicast Protocols Configuration Guide.
