Description

Set the time that the device waits before electing a designated forwarder (DF).

Customer edge (CE) devices require a DF when they are multihomed to more than one provider edge (PE) device. Without a designated forwarder, multihomed hosts would receive duplicate packets. The connections between a multihomed CE device and its multihoming peer PE devices form an Ethernet segment identified by an Ethernet segment identifier (ESI). The multihomed peer devices choose DFs for an ESI based on EVPN Type 4 route advertisements. EVPN Type 4 routes are called Ethernet segment routes.

Options

seconds

Time in seconds that a multihomed CE device waits before electing a DF based on the EVPN Type 4 routes it receives.
