Multiple customer VLANs can be bundled in a single EVI instance.
The attachment circuit (AC) port is configured with a tag protocol identifier (TPID) that is different from that of the incoming traffic; the port is also configured with an untagged VLAN. All the traffic coming in on this port is treated as untagged traffic. The following figure illustrates this topology.
Note
This feature is not supported on the SLX 9150 or the SLX 9250.
The untagged VLAN configured on the AC port is extended through the EVPN. All the traffic arriving on this untagged VLAN is bundled with a single Virtual Network Identifier (VNI). The MAC addresses are learned on the untagged VLAN that is configured on that port, irrespective of the VLAN tag of the incoming packet. As all the traffic on this port is mapped to a single flooding domain, MAC addresses on this VLAN must be unique.
The following example illustrates a configuration with a VLAN on an Ethernet port.
device(conf-if-eth-0/1)# switchport device(conf-if-eth-0/1)# switchport mode access device(conf-if-eth-0/1)# switchport access vlan 200 device(conf-if-eth-0/1)# tag-type 9100
The following example illustrates a configuration with a bridge domain (BD) logical interface (LIF) on an Ethernet port.
device(conf-if-eth-0/1)# switchport device(conf-if-eth-0/1)# switchport mode trunk-no-default-native device(conf-if-eth-0/1)# logical-interface ethernet 0/1.1 untagged vlan 200 device(conf-if-eth-0/1)# tag-type 9100
