In platform-as-a-service (PaaS) and infrastructure-as-a-service (IaaS) deployments, each customer uses a separate physical interface to connect to a leaf device. Without VLAN translation, the customer edge VLAN must use the same VLAN ID (VID). 252! interface FastEthernet4/0. Each VLAN is mapped to a single EVPN instance (EVI), resulting in a separate bridge table for each VLAN. 168. In this small lab I've just wanted to try out root# show interfaces ge-0/0/0 { flexible-vlan-tagging; mtu 9192; encapsulation extended-vlan-bridge; ether-options { ethernet-switch-profile { tag-protocol-id 0x8100; } } unit 426 { family ethernet-switching { interface-mode trunk; vlan { members 426; } } } unit 4000 { vlan-id 4000; } } ge-0/0/1 { flexible-vlan-tagging; native-vlan-id 150; encapsulation extended-vlan Subscriber management supports the creation of subscriber interfaces over point-to-point MPLS pseudowires. You can run following config: [edit] root# show interfaces ge-0/0/4 flexible-vlan-tagging; native-vlan-id 10; I ended up using vlan-ccc encapsulation and interface-switch under protocols>connections. l2circuits are a simple P2P PW only with a large benefit of no MAC-learning. The East-coast EX4550-32F (Junos: 15. vlan-tagging. When the customer sites participating in a VPLS domain send traffic of different tag heights (untaggged, single tagged, or dual tagged packets) across a service, Internet service Dec 20, 2024 · Simultaneously supports transmission of 802. PPP encapsulation is the default encapsulation type for physical interfaces. set interfaces xe-0/0/9 flexible-vlan-tagging set interfaces xe-0/0/9 mtu 9192 set interfaces xe-0/0/9 gigether-options no-flow-control set interfaces xe-0/0/9 unit 616 encapsulation vlan-bridge set interfaces xe-0/0/9 Because i dont include vlan-id statement in routing-instances VPLS-TEST so the default behavior is vlan-id none. This feature thus provides Because i dont include vlan-id statement in routing-instances VPLS-TEST so the default behavior is vlan-id none. 0: 10. 1/32 ! interface Vxlan 1 vxlan source-interface loopback 1 vxlan vlan 100 vni 10100 vxlan vlan 200 vni 10200 vxlan vlan 100 flood vtep 2. Created 2020-03-11. Mar 11, 2020 · [Junos] "Link encapsulation type is not valid for device type" Article ID KB35571. 10. This is my situation:Uplink vs ISP Provider Optica Fiber:Cisco Router ----> TRUNK SRX supports flexible vlan tagging on Junos 12. A CE router at the egress of that path Introduction I've started reading Chapter 2 of Juniper MX Series book a few days ago, where it talks about Bridging, VLAN Mapping and IRB interfaces. 255. So basically VLAN-CCC is adding another VLAN ID. 1R7-S11. It seems that this router uses a different command syntax. Ether2, 802. Junos OS for MX Series 3D Universal Edge Routers . The issue is that I need to have mismatched l2circuit encapsulation-type on either side. Tunnels connect discontinuous subnetworks and enable encryption interfaces, virtual private networks (VPNs), and MPLS. On the SRX : The command > show interface terse don't show the interface ge-0/0/2. d/29; } } unit 2 { family inet { address w. You will have to configure the vlans allowed on the Juniper side of the trunk (Juniper default is none allowed), and make sure the vlans are defined under the 'vlans' stanza. Ethernet interfaces in VLAN mode can have Configure the switch to preserve the original VLAN tag (in the inner Ethernet packet) when performing Virtual Extensible LAN (VXLAN) encapsulation. This config should work. 5 VPNs, the translation cross-connect (TCC) encapsulation types allow you to configure different encapsulation types at the ingress and egress of a Layer 2 VPN or the ingress and egress of a Layer 2 circuit. Layer-2 VPN connections: Legend for connection status (St) EI -- encapsulation invalid NC -- interface encapsulation not CCC Hi, you can run multiple services (see config sniplet below) on the same phy interface but on different VLANs (VPLS, xSTP, L3 VPN, CCC, L2 VPN etc). 191) side of the l2circuit service is configured with encapsulation-type ethernet as shown: [email protected]> show configuration | Dec 20, 2024 · Dynamic interface configuration of the logical link-layer encapsulation type. Hello Franky. 513 ] Encapsulation: VLAN-VPLS Input packets : 0 Output packets: 0 Protocol vpls, MTU: 1518 Flags: Is-Primary Logical interface Q-in-Q was introduced for the Juniper Networks EX Series Switches starting with Junos OS Release 9. 30. For some devices, you may also specify the logical link layer encapsulation type. This example is based on a centrally-routed with bridging (CRB) EVPN architecture in a 5-stage Clos fabric. 1X46 onwards. 2R1, it is not supported; it may be added in future releases as an Enhancement Request. Symptoms. So somethings are excess in my configure ! On PE1, the interface ae19 push vlan 20 to the packets (double vlan tags). 3R1, VLAN translation was not supported. But, this encapsulation is supported by certain types of hardware. This section describes how port mirroring sends network traffic to analyzer applications. This topic describes how to configure a Layer 2 circuit on a logical interface bound to a list of VLAN IDs. The MX Series routers support two methods of configuring bridge interfaces: enterprise and service provider styles. interfaces { ge-0/0/0 { vlan-tagging; encapsulation extended-vlan-bridge; unit 1 Junos OS MX Series 3D Universal Edge Routers Solutions Guide . y. 1q, MPLS label, PPP. 4R1, you can configure aggregated Ethernet interfaces and aggregated Ethernet logical interfaces to automatically derive Ethernet segment identifiers (ESIs) from the Link Aggregation Control Protocol (LACP) configuration. unit Example. Figure 1 shows a simple multihomed network with a customer edge (CE) device multihomed to two provider edge (PE) So it seems Juniper switches (and lots of vendors) are not designed to terminate double-tagged 802. This example describes how to configure Ethernet VPLS encapsulation on a Gigabit Ethernet IQ or Gigabit Ethernet physical interface and enable the VPLS family on the interface. Simultaneously supports transmission of 802. 0 and supports both port-based and VLAN-based encapsulation over pseudowire.
