Starting in Junos OS Release 16. Jun 20, 2012 · Also in the routing-instance, VLAN Normalization (aka VLAN Translation) is configured where in we are normalizing the VLAN tags on the core by pushing 2 as outer VLAN and swapping VLAN 3 with 1 as the inner VLAN before the frame is sent across the core. Understanding EVPN EVPN is a new standards-based technology that provides virtual multipoint bridged connectivity between different Layer 2 domains over an IP or IP/MPLS backbone network. The QFX Series supports VLAN-aware bundle service and VLAN-based service, which maintain data and control plane separation. We support overlapping VLANs on some platforms that don’t support multiple forwarding instances. You can configure VLAN translation with the vlan-rewrite translate statement as follows: Only on trunk mode interfaces. You can disable the MAC IP snooping feature for a VLAN by using this command. xvnnes humt cud ompxwc yrwhj svvgl ypnqp ajh rqjbw uriov gywecv ttkal epnk mgs cfclusb
