Default level

2: System level

Parameters

ccc-connection-name: Name for the CCC connection, a string of 1 to 20 characters. It is used for uniquely identifying a CCC connection on a PE.

interface interface-type interface-number: Specifies the interface connecting the local CE by its type and number.

in-label in-label-value: Specifies the incoming label, in the range of 16 to 1023.

out-label out-label-value: Specifies the outgoing label, in the range of 16 to 1023.

nexthop ip-address: Specifies the IP address of the next hop.

out-interface interface-type interface-number: Specifies the outgoing interface by its type and number.

control-word: Enables the control word option.

no-control-word: Disables the control word option.

Only L2VPNs using ATM, PPP, Frame Relay, or HDLC encapsulation support the control word option.

Description

Use the ccc interface in-label out-label command to create a remote CCC connection between CEs connected to different PEs.

Use the undo ccc command to delete a CCC connection.

This command must be configured on both of the PEs.

A PE uses connection names to identify different CCC connections. A CCC connection can have different names on different PEs.

If a P router is connected with a PE, you must configure a static LSP between them.

NOTE:

Only when the link that the outgoing interface connects is a point-to-point link, can you use the out-interface keyword to specify the outgoing interface. If the link is not a point-to-point link but, for example, a link connecting to a Layer 3 Ethernet interface, VLAN interface, or Layer 3 aggregate interface, you must use the nexthop keyword to specify the IP address of the next hop.

Examples

# Create a remote CCC connection from CE A to CE B, setting the incoming interface to that connecting CE A, namely GigabitEthernet 3/1/2; the next hop to 20.1.1.2; the incoming label to 100; and the outgoing label to 200.

Default level

2: System level

Parameters

destination: IP address of the peer PE.

vc-id: VC ID of the L2VPN connection, in the range of 1 to 4294967295.

control-word: Enables the control word option.

no-control-word: Disables the control word option.

ethernet: Specifies the PW encapsulation type of Ethernet. In Ethernet mode, P-Tag is not transferred on the PW. If a packet from a CE contains the service delimiter, the PE removes the service delimiter and adds a PW label and tunnel label into the packet before sending the packet out. If a packet from a CE contains no delimiter, the PE directly adds a PW label and a tunnel label into the packet and then sends the packet out. For a packet to be sent downstream, you can configure the PE to add or not add the service delimiter into the packet, but rewriting and removing of existing tags are not allowed.

vlan: Specifies the PW encapsulation type of VLAN. In VLAN mode, packets transmitted over the PW must carry a P-Tag. For a packet from a CE, if it contains the service delimiter, the PE keeps the P-TAG unchanged or changes the P-tag to the VLAN tag expected by the peer PE or to a null tag (the tag value is 0), and then adds a PW label and a tunnel label into the packet before sending the packet out. If the packet contains no service delimiter, the PE adds the VLAN tag expected by the peer PE or a null tag, and then a PW label and a tunnel label into the packet before sending the packet out. For a packet to be sent downstream, the PE rewrites, removes, or retains the service delimiter depending on your configuration.

tunnel-policy tunnel-policy-name: Specifies the tunneling policy for the VC. The tunneling policy name is a case-insensitive string of 1 to 19 characters.

Description

Use the mpls l2vc command to create a Martini L2VPN connection.

Use the undo mpls l2vc command to delete the Martini connection on the CE interface.

Only L2VPNs that use ATM, PPP, FR, or HDLC encapsulation support the control word option.

The PW encapsulation type can be Ethernet or VLAN. The router allows you to specify the PW encapsulation type for only Layer 3 Ethernet interfaces and subinterfaces, Layer 3 virtual Ethernet interfaces and subinterfaces, and VLAN interfaces. When not specified, the PW encapsulation type depends on the interface type: it is Ethernet on Layer 3 Ethernet interfaces and Layer 3 virtual Ethernet interfaces, and VLAN on Layer 3 Ethernet subinterfaces, Layer 3 virtual Ethernet subinterfaces, and VLAN interfaces.

Related commands: tunnel select-seq.

CAUTION:

You must configure the PVC and MAP for an ATM interface before using the mpls l2vc destination vcid [ tunnel-policy tunnel-policy-name ] [ control-word | no-control-word ] [ ethernet | vlan ] command on the ATM interface. For more information about PVC and MAP configuration, see Layer 2—WAN Configuration Guide.

Parameters

ethernet: Specifies the PW transport mode as Ethernet.

vlan: Specifies the PW transport mode as VLAN.

Description

Use the trans-mode command to specify the PW transport mode.

Use the undo trans-mode command to restore the default.

By default, the PW transport mode is VLAN.

In Ethernet mode, P-Tag is not transferred on the PW. If a packet from a CE contains the service delimiter, the PE removes the service delimiter and adds a PW label and a tunnel label into the packet before sending the packet out. If a packet from a CE contains no delimiter, the PE directly adds a PW label and a tunnel label into the packet and then sends the packet out. For a packet to be sent downstream, you can configure the PE to add or not add the service delimiter into the packet, but rewriting and removing of existing tags are not allowed.

In VLAN mode, packets transmitted over the PW must carry a P-Tag. For a packet from a CE, if it contains the service delimiter, the PE keeps the P-Tag unchanged or changes the P-tag to the VLAN tag expected by the peer PE or to a null tag (the tag value is 0), and then adds a PW label and a tunnel label into the packet before sending the packet out. If the packet contains no service delimiter, the PE adds the VLAN tag expected by the peer PE or a null tag, and then a PW label and a tunnel label into the packet before sending the packet out. For a packet to be sent downstream, the PE rewrites, removes, or retains the service delimiter depending on your configuration.

Parameters

vpn-target&<1-16>: Adds VPN target extended community attributes to the import or export VPN target extended community list. &<1-16> means that you can specify up to 16 VPN targets.

A VPN target can be a string of 3 to 21 characters in any of the following formats:

· 16-bit AS number:32-bit user-defined number. For example, 101:3.

· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.

· 32-bit AS number:16-bit user-defined number, where the AS number must be equal to or greater than 65536. For example, 65536:1.

both: Uses the specified VPN targets as both import targets and export targets. The both keyword is also used when you do not specify any of both, export-extcommunity, and import-extcommunity.

export-extcommunity: Uses the specified VPN targets as export targets.

import-extcommunity: Uses the specified VPN targets as import targets.

all: Removes all VPN targets.

Description

Use the vpn-target command to configure VPN targets for a VPN.

Use the undo vpn-target command to delete the VPN targets configured for a VPN.

By default, no VPN targets are configured for a VPN and you must configure them when creating the VPN.

Examples

# Configure VPN targets for the VPN vpn1.

Parameters

peer-ip-address: IP address of the remote peer.

pw-id pw-id: Specifies the PW ID of the Martini MPLS L2VPN connection. pw-id ranges from 1 to 4294967295.

access-mode: Specifies the access mode of the service instance as Ethernet or VLAN. The default access mode is VLAN.

ethernet: Specifies the access mode of Ethernet.

vlan: Specifies the access mode of VLAN.

mtu mtu-value: Specifies the MTU, which ranges from 46 to 65535 and defaults to 1500.

pw-class class-name: Specifies a PW class template by its name. class-name is a case-insensitive string of 1 to 19 characters. If you do not specify a PW class template, or you specify a PW class template but the PW class template does not specify a tunneling policy or the specified tunneling policy is not configured, the default tunneling policy will be used. The default tunneling policy selects only one tunnel (no load balancing) in this order: LSP tunnel, CR-LSP tunnel.

Description

Use the xconnect peer command to create a Martini MPLS L2VPN connection for a service instance.

Use the undo xconnect peer command to delete the MPLS L2VPN connection of a service instance.

The access mode of a service instance can be VLAN or Ethernet.

· VLAN: The Ethernet header of a packet sent from a CE to a PE or from a PE to a CE includes a VLAN tag that is added in the header as a service delimiter for the service provider network to identify the user. The tag is called a P-Tag.

· Ethernet: The Ethernet header of a packet sent from a CE to a PE or from a PE to a CE does not contain any service delimiter. If the header contains a VLAN tag, it is the internal VLAN tag of the user and means nothing to the PE. Such an internal VLAN tag of a user is called a U-Tag.

NOTE:

· The MTU specified by this command is advertised through LDP and used for PW negotiation.

· The MTU specified by this command is only used for possible parameter negotiation.

· The xconnect peer command is available for service instances with the ID in the range of 1 to 4094.

Related commands: pw-class.

Examples

# For service instance 100, create a Martini MPLS L2VPN connection and specify the packet matching VLAN ID as 100.
