Usage Guidelines

Usage Scenario

On a multicast EVPN, an mLDP P2MP tunnel has only one root node but may have multiple leaf nodes. To specify a leaf node and enter the EVI I-PMSI-leaf view for leaf node configurations, run the leaf 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

# Configure the current device as a leaf node for a multicast EVPN.
