vpn-speed: Upper speed limit of the VPLS instance in kbps, in the range of 64 to 4,194,303. The system automatically calculates a speed that is the greatest multiple of 64 kbps between 64 and the specified value.

Description

Use the bandwidth command to set the upper speed limit of a VPLS instance.

Use the undo bandwidth command to restore the default.

By default, the upper speed limit of a VPLS instance is 102,400 kbps.

The bandwidth command, together with the broadcast-restrain command, defines a threshold that is used in suppressing the broadcast traffic (including broadcast, multicast, and unknown unicast traffic) of the VPLS instance. When the speed of the broadcast traffic exceeds the threshold, that is, the product of the speed limit and the broadcast suppression percentage, the extra broadcast traffic will be dropped.

NOTE:

This feature is available only when the system working mode is SPE. For more information about system working modes, see Fundamentals Configuration Guide.

# Set the upper speed limit of VPLS instance aaa to 10 Mbps.

Parameters

ratio: Broadcast suppression percentage of the VPLS instance, in the range of 1 to 100.

Description

Use the broadcast-restrain command to set the broadcast suppression percentage of a VPLS instance.

Use the undo broadcast-restrain command to restore the default.

By default, the broadcast suppression percentage of a VPLS instance is 5.

This command, together with the bandwidth command, defines a threshold that is used in suppressing the broadcast traffic (including broadcast, multicast, and unknown unicast traffic) of the VPLS instance. When the speed of the broadcast traffic exceeds the product of the speed limit and this ratio, the extra broadcast traffic will be dropped.

NOTE:

This feature is available only when the system working mode is SPE. For more information about system working modes, see Fundamentals Configuration Guide.

trans-mode

Syntax

trans-mode { ethernet | vlan }

undo trans-mode

View

PW class template view

Default level

2: System Level

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. For a packet from a CE, if it contains the service delimiter, the PE removes the service delimiter and adds a PW label and tunnel label into the packet before forwarding the packet. Otherwise, the PE directly adds a PW label and tunnel label into the packet and then forwards the packet. For a packet to be sent downstream, whether the PE adds the service delimiter into the packet depends on your configuration. However, 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.

vpn-target (VSI BGP view)

Syntax

vpn-target vpn-target &<1-16> [ both | export-extcommunity | import-extcommunity ]

undo vpn-target { all | vpn-target &<1-16> } [ both | export-extcommunity | import-extcommunity ]

View

VSI BGP view

Default level

2: System level

Parameters

vpn-target&<1-16>: Adds VPN target extended community attributes to the import VPN target extended community attribute list (Import Target) or export VPN target extended community attribute list (Export Target). &<1-16> means that you can add up to 16 VPN targets.

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

· 16-bit AS number:32-bit user-defined number, such as 101:3.

· 32-bit IP address:16-bit user-defined number, such as 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 target values 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 one or more VPN targets for a VPLS instance.

Use the undo vpn-target command to remove the specified or all VPN targets of a VPLS instance.

By default, no VPN targets are configured and you must configure VPN targets when creating a VPLS instance.

Examples

# Configure VPN targets for the VPLS instance aaa.

vsi

Syntax

vsi vsi-name [ { auto | static [ hub-spoke | p2p ] } | minm i-sid i-sid ] *

undo vsi vsi-name

View

System view

Default level

2: System level

Parameters

vsi-name: Name of the VSI, a case-insensitive string of 1 to 31 characters. Hyphens (-) are not allowed.

auto: Configures the peer discovery mechanism as dynamic. This corresponds to BGP mode.

static: Configures the peer discovery mechanism as static. This corresponds to LDP mode.

hub-spoke: Enables the hub-spoke capability for the instance whose peer discovery mechanism is static.

p2p: Enables the P2P (PW to PW) capability for the VSI whose peer discovery mechanism is static. The P2P feature is used to associate two PWs to set up a multi-hop PW.

NOTE:

The router does not support the minm i-sid i-sid option.

Description

Use the vsi command to create a VSI and enter VSI view. If the specified VSI already exits, you enter the VSI view directly.

Use the undo vsi command to remove a VSI.

Note the following when using this command:

· To create a VSI, specify a globally unique name for it, and specify the peer discovery mechanism. If you specify the peer discovery mechanism as static, you can also enable hub-spoke or P2P for the VPLS instance as needed.

· To enter the view of an existing VSI, use the vsi vsi-name command without specifying any other parameters.

· Before creating a VPLS instance, you need to enable L2VPN and MPLS L2VPN by using the l2vpn command and the mpls l2vpn command.

Related commands: display vsi, mpls l2vpn, and l2vpn.

Examples

# Create VPLS instance aaa and specify the peer discovery mechanism of the VPLS instance as static.

<Sysname> system-view

[Sysname] vsi aaa static

[Sysname-vsi-aaa]

# Create VPLS instance bbb, specify the peer discovery mechanism of the VPLS instance as static, and enable the P2P capability.

<Sysname> system-view

[Sysname] vsi bbb static p2p

vsi-id

Syntax

vsi-id vsi-id

View

VSI LDP view

Default level

2: System level

Parameters

vsi-id: ID for the VPLS instance, in the range of 1 to 4294967295.

Description

Use the vsi-id command to specify the ID of a VPLS instance.

On PEs in the same VPN, be sure to specify the same VSI ID for the VPLS instances that correspond to the VPN.

Examples

# Set the VSI ID of VPLS instance aaa to 100.

<Sysname> system-view

[Sysname] vsi aaa static

[Sysname-vsi-aaa] pwsignal ldp

[Sysname-vsi-aaa-ldp] vsi-id 100

xconnect vsi

Syntax

xconnect vsi vsi-name [ access-mode { ethernet | vlan } | { hub | spoke } ] *

undo xconnect vsi

View

Service instance view

Default level

2: System level

Parameters

vsi-name: Name of a VPLS instance, a case-insensitive string of 1 to 31 characters. Hyphens (-) are not allowed.

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

ethernet: Specifies the Ethernet access mode.

vlan: Specifies the VLAN access mode.

hub: Specifies the access mode of the VPLS instance as hub.

spoke: Specifies the access mode of the VPLS instance as spoke, which is also the default when the VPLS instance is enabled with the hub-spoke capability.

Description

Use the xconnect vsi command to associate a VPLS instance with the service instance on a specific interface.

Use the undo xconnect vsi command to remove the association.

By default, a service instance is not associated with any VPLS instance.

The access mode of a service instance can be either of the following:

· 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 following:

· Only when the VPLS instance is enabled with the Hub-Spoke capability, can you further specify the access mode as Hub or Spoke. The default is Spoke.

· In Hub-Spoke networking mode of VPLS, data between Spoke sites must be exchanged through Hub sites. Direct data exchange between Spoke sites is not allowed.

· For VPLS, signaling advertisement uses the MTU of the VPLS instance.

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

Related commands: service-instance.

Examples

# Associate service instance 200 of GigabitEthernet 3/1/3 with VPLS instance vsi200 and specify the matching external VLAN tag as 200.
