Description
Statically configure a list of one or more remote virtual tunnel endpoints (VTEPs), and map the list to a particular bridge domain or VLAN.
If you have previously configured EVPN-VXLAN on a device, then later configure static VXLAN, you must reboot the device to let static VXLAN take effect.
When configuring a static remote VTEP list, keep the following in mind:
When specifying remote VTEPs at the bridge domain level in a routing instance, you must also specify the same VTEPs at the global level in the same routing instance. When specifying remote VTEPs at the VLAN level in the default switching instance, you must also specify the same VTEPs at the global level in the default switching instance. To illustrate this point, note the following in sample configurations 1 and 2:
Routing instance
rt1and the default switching instance include the VTEPs with the loopback addresses of 10.1.1.1 and 10.1.1.2.Bridge domain
bd1andVLAN-1include the VTEPs with the loopback addresses of 10.1.1.1 and 10.1.1.2.Bridge domain
bd2andVLAN-2include the VTEP with the loopback address of 10.1.1.1.Bridge domain
bd3andVLAN-3don’t include a static remote VTEP list. As a result,bd3andVLAN-3inherit all VTEPs specified in routing instancert1and the default switching instance (the VTEPs with the loopback addresses of 10.1.1.1 and 10.1.1.2), respectively.
To replicate and flood broadcast, unknown unicast, and multicast (BUM) traffic, you must specify the
ingress-node-replicationconfiguration statement at the[edit vlans name vxlan],[edit bridge-domains name vxlan], or[edit routing-instances name bridge-domains name vxlan]hierarchy level. In sample configuration 1,ingress-node-replicationis configured for all bridge domains in routing instancert1. In sample configuration 2,ingress-node-replicationis configured for all VLANs in the default switching instance.Note that this ingress node replication configuration restricts the BUM traffic flood domain to only those VTEPs mapped to a particular bridge domain or VLAN. For example, for sample configurations 1 and 2, the BUM traffic flood domain is restricted as described for each bridge domain and VLAN, respectively:
bd1andbd3;VLAN-1andVLAN-3—BUM traffic is flooded to the VTEPs with the loopback addresses of 10.1.1.1 and 10.1.1.2.bd2;VLAN-2—BUM traffic is flooded to the VTEP with the loopback address of 10.1.1.1.
To ensure that BUM traffic is flooded to only those VTEPs mapped to a particular VLAN, we strongly recommend that the static VTEP lists on all QFX5XXX switches are symmetric. We provide this guidance to avoid a situation where, for example, switch 1’s list includes switches 2 and 3, switch 2’s list includes switches 1 and 3, and switch 3’s list includes only switch 2. Because of this asymmetric configuration, when switch 1 sends BUM traffic to switch 3, switch 3 will forward the traffic even though switch 1 is not on its list.
