stp: Specifies all STP protocols that include MSTP and RSTP. udld: Specifies the UDLD protocol. vtp: Specifies the VTP protocol. drop: Drops packets of a protocol. tunnel: Tunnels the protocol packets. The PE replaces the protocol destination MAC address of packets from the private network with the L2PT multicast MAC address. If the destination MAC address of packets from the public network is the L2PT multicast MAC address, the PE replaces the MAC address with the protocol destination MAC address.
Configure the same destination multicast MAC address on the local and remote PEs when the l2protocol-tunnel command with the tunnel keyword, or with the tunnel and experimental keywords is configured on the PEs. Examples # Configure the destination multicast MAC address as 0010-cd10-10ac. system-view [Sysname] l2protocol-tunnel mac-address 0010-cd10-10ac Related commands l2protocol-tunnel l2vpn Use l2vpn to enable L2VPN and enter L2VPN view.

Examples # Enter BGP L2VPN address family view. system-view [Sysname] bgp 100 [Sysname-bgp] l2vpn-family [Sysname-bgp-af-l2vpn] mpls l2vc Use mpls l2vc to create a Martini VC on a PE-CE interface of a PE. Use undo mpls l2vc to delete the Martini VC on the interface.
revertive: Enables support for switchback. With this keyword specified, when the primary VC recovers, traffic is switched from the backup VC back to the primary VC automatically. If you do not specify this keyword, traffic will not be switched back automatically. wtr-time wtr-time: Specifies the switchback delay time. When the primary VC recovers, the device waits for the switchback delay time before switching the traffic from the backup VC back to the primary VC.
Examples # Assume that a primary VC and a backup VC are created on Ethernet 1/1. Switch traffic from the active VC to the standby VC on the interface. system-view [Sysname] interface ethernet 1/1 [Sysname-Ethernet1/1] mpls l2vc switchover mpls l2vpn Use mpls l2vpn to enable MPLS L2VPN. Use undo mpls l2vpn to disable MPLS L2VPN and delete all L2VPN configurations. Syntax mpls l2vpn undo mpls l2vpn Default MPLS L2VPN is disabled.
Default command level 2: System level Usage guidelines Before executing this command, you must enable MPLS L2VPN by using the mpls l2vpn command. Only SVC MPLS L2VPN supports Soft GRE. To set up a remote MPLS L2VPN connection between two PEs, you must use MPLS LDP, MPLS TE, or GRE to set up a public tunnel that carry the VC. You can use Soft GRE to replace the complicated public tunnel configuration.
hdlc: Uses HDLC encapsulation. ppp: Uses PPP encapsulation. vlan: Uses VLAN encapsulation. control-word: Enables the control word function. no-control-word: Disables the control word function. Usage guidelines The VC encapsulation type specified by this command must match that of the AC link. Only L2VPNs that use encapsulation types of PPP, HDLC, FR DLCI, FR port mode, ATM AAL5 transparent transport, and ATM cell transparent transport support the control word function.
Parameters destination: Specifies the IP address of the peer PE. vc-id: Specifies an ID for the VC, in the range of 1 to 4294967295. control-word: Enables the control word function. ethernet: Specifies the VC encapsulation type as Ethernet. ip-interworking: Enables the SVC to support IP interworking. If you specify this keyword, when the PE receives a packet from an AC bound to the SVC, it extracts the IP packet from the packet, sends the IP packet to the peer PE over the SVC.
[Sysname] interface serial 2/0 [Sysname-Serial2/0] mpls static-l2vc 1.1.1.9 100 backup-peer 2.2.2.9 200 [Sysname-Serial2/0-static-l2vc] Related commands tunnel-policy mpls static-l2vc (for ordinary SVC) Use mpls static-l2vc to create a static VC between CEs connected to different PEs. Use undo mpls static-l2vc to delete the static VC.
If you do not specify a tunneling policy, or if you specify a nonexistent tunneling policy, the default policy is used for the VC. The default tunneling policy selects only one tunnel in this order: LSP tunnel, GRE tunnel, CR-LSP tunnel. For information about how to configure a tunneling policy, see MPLS Configuration Guide. Only L2VPNs that use encapsulation types of PPP, HDLC, FR DLCI, FR port mode, ATM AAL5 transparent transport, and ATM cell transparent transport support the control word function.
Use undo mtu to restore the default. Syntax mtu mtu undo mtu Default The MPLS L2VPN MTU is 1500. Views MPLS L2VPN view Default command level 2: System level Parameters mtu-value: Specifies the MTU for the L2VPN, in the range of 128 to 1500. Usage guidelines HP recommends not using the mtu command, because it affects only parameter negotiations between PEs and does not instruct traffic forwarding. Examples # Set the MPLS L2VPN MTU to 1000.
-m wait-time: Specifies the interval for sending Echo Request messages. The value range for the wait-time argument is 1 to 10000, and the default is 200, in milliseconds. -r reply-mode: Specifies the reply mode of a receiver in response to an Echo Request message. The reply-mode argument can be 1 or 2 where 1 means "Do not respond" and 2 means "Respond by using a UDP packet." The default is 2. -s packet-size: Specifies the payload length of the Echo Request messages.
Usage guidelines If you configure PPP to support IPCP negotiation without IP address on a PE, the PE ignores the local interface address when it performs IPCP negotiation with the peer CE in the PPP NCP phase. On an interface, the IPCP negotiation without IP address configuration takes precedence over the IPCP proxy IP address configuration, and the IPCP proxy IP address configuration takes precedence over the local interface IP address configuration.

Usage guidelines Sometimes, although a reservation request does not pass admission control on some node, you might want to store the resource reservation state for it while allowing other requests to use the resources reserved for the request. In this case, the node transits to the blockade state and a blockade state block (BSB) is created on each downstream node. When the number of non-refreshing times exceeds the blockade multiplier, the blockade state is removed.
