Hierarchy Level


Elect the designated forwarder (DF) in a multihomed Ethernet VPN (EVPN) network using an administrative preference value assigned to an Ethernet segment identifier (ESI). This preference value is exchanged in the type 4 route using the DF election extended community. On receiving the type 4 route, the candidate DF devices are ordered based on the configured preference value and the IP address.


preference value

Preference value for EVPN multihoming DF election.

By default, the preference-based DF election process is based on the highest preference value configured. If the configured preference value is the same on all the candidate PE devices, then the lowest IP address is used to elect the DF.

To enable DF election based on the lowest preference value configured, include the designated-forwarder-preference-least statement at the [edit routing-instance routing-instance-name protocols evpn] hierarchy level.

  • Default: 32767
