Function

The root command specifies the current device as the root node for a multicast EVPN, and displays the EVI I-PMSI root view.

The undo root command deletes the root node configuration for a multicast EVPN and all configurations in the EVI I-PMSI root view.

Usage Guidelines

Usage Scenario

On a multicast EVPN, the root node is the ingress of an mLDP P2MP tunnel. An mLDP P2MP tunnel has multiple leaf nodes, but only one root node. To specify the current device as the root node for the multicast EVPN and enter the EVI I-PMSI root view for root node configuration, run the root command.

Precautions

In a dual-homing scenario, if the dual-homing PEs are configured as root nodes using the root command, the two PEs can no longer be configured as leaf nodes using the leaf command.

Example

# Specify the current device as the root node for a multicast EVPN and display the EVI I-PMSI root view.
