EVPN Over VXLAN Encapsulation Configuration Overview for QFX Series and EX4600 Switches

 

This topic provides information about configuring Ethernet VPN (EVPN) with Virtual Extensible Local Area Networks (VXLAN) data plane encapsulation on QFX5100, QFX5110, QFX5200, QFX5210, and EX4600 switches.

The configuration statements described in this topic are in the switch-options and protocols evpn hierarchy levels.

CLI Statement

Description

route-distinguisher

Specifies an identifier attached to a route—this enables you to distinguish to which VPN or VPLS the route belongs. Each routing instance must have a unique route distinguisher associated with it. The route distinguisher is used to place bounds around a VPN so that the same IP address prefixes can be used in different VPNs without having them overlap.

vrf-target

Specifies a VRF target community. In effect, this statement configures a single policy for import and a single policy for export to replace the per-VRF policies for every community. import, export, and auto options are available.

vrf-import

Specifies how routes are imported into the VRF table of the local provider edge (PE) router or switch from the remote PE.

vrf-export

Specifies how routes are exported from the local PE router’s VRF table to the remote PE router.

designated-forwarder-election-hold-time

Establishes when a designated forwarder is required for customer edge (CE) devices that are multihomed to more than one provider edge (PE) device. Without a designated forwarder, multihomed hosts receive duplicate packets. Designated forwarders are chosen for an Ethernet segment identifier (ESI) based on type-4 route advertisements.

encapsulation vxlan

Configures a VXLAN encapsulation type.

extended-vni-list and extended-vni-all

Establishes which VXLAN virtual network identifiers are designated as part of the virtual switch instance.

multicast-mode

Configures the multicast server mode for delivering traffic and packets for EVPN.

vni-options

Configures different route targets for each VXLAN virtual network identifier instance under vni-options.

show route table

Displays both imported EVPN routes, and export/import EVPN routes for the default-switch routing instance.

show configuration protocols evpn

Displays results of the extended-vni-list and vni-options statements.
