Parameters

action: Specifies the action to be taken on frames with unknown source MAC addresses when the AC has learned the maximum number of MAC addresses.

· discard—Drops the frames.

· forward—Forwards the frames. This is the default action.

alarm: Enables or disables the alarm feature. The alarm feature generates a log message when the number of MAC address entries on the AC reaches the maximum or drops below 90% of the maximum.

· disable—Disables the alarm feature. This is the default setting.

· enable—Enables the alarm feature.

maximum mac-limit: Specifies the maximum number of MAC addresses that a Layer 3 interface type AC can learn. The value range for the mac-limit argument is 0 to 1048575.

Usage guidelines

Use this command to prevent a single AC from occupying too many MAC address entry resources.

Examples

# On interface GigabitEthernet 3/1/1 associated with VSI aaa, limit the maximum number of MAC addresses that the interface can learn to 1024. Configure the interface to drop frames with unknown source MAC addresses when the limit is reached, and enable the alarm feature.

Parameters

ip-address: Specifies the LSR ID of the peer PE on the backup PW.

pw-id pw-id: Specifies a PW ID for the backup PW, in the range of 1 to 4294967295.

in-label label-value: Specifies the incoming label for the backup PW. The value range for the label-value argument is 16 to 1023.

out-label label-value: Specifies the outgoing label for the backup PW, in the range of 16 to 1048575.

pw-class class-name: Specifies a PW class by its name, a case-sensitive string of 1 to 19 characters. You can specify a PW class to configure the PW data encapsulation type for the backup PW. If you do not specify a PW class, the PW data encapsulation type of the backup PW is VLAN.

tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-insensitive string of 1 to 19 characters. If you do not specify a tunnel policy, the backup PW uses the default tunnel policy.

Usage guidelines

This command configures a backup PW for a PW to implement PW redundancy. The backup PW is used when the primary PW fails.

You must assign the backup PW a different peer LSR ID and PW ID than any existing VPLS PWs or cross-connect PWs.

A backup PW has the same hub and no-split-horizon attributes as its primary PW.

If both the default PW ID in the default-pw-id command and a PW ID in the backup-peer command are configured, the PW ID in the backup-peer command is used. If only the default PW ID is configured, the default PW ID is used. If no default PW ID is configured, you must provide a PW ID in the backup-peer command.

A static PW must have a different incoming label than an existing static LSP or static CRLSP. If they are the same, the static PW is not available, even if you change the incoming label of the static LSP or the static CRLSP. To make the static PW available, delete the static PW, and reconfigure it with an unused incoming label.

The PW classes of the primary and backup PWs must have the same flow label configuration.

Examples

# Configure a primary and a backup LDP PW for VSI vpn1, and specify the peer PE address and PW ID of the primary PW as 4.4.4.4 and 100, and those of the backup PW as 5.5.5.5 and 200.

verbose: Displays detailed information. If you do not specify this keyword, the command displays brief information.

Usage guidelines

LDP advertises FEC-to-PW label bindings in the following ways:

· After you specify a remote PE with the peer command, LDP advertises an FEC 128-to-PW label binding to the remote PE.

· After BGP discovers a remote PE, LDP advertises an FEC 129-to-PW label binding to the remote PE.

This command can display PW labels as follows:

· If you specify the pw-id pw-id option, this command displays PW labels for FEC 128.

· If you specify the vpls-id vpls-id option, this command displays PW labels for FEC 129.

· If you do not specify pw-id pw-id or vpls-id vpls-id, this command displays PW labels for both FEC 128 and FEC 129.

encapsulation

Use encapsulation to configure a packet match criterion for an Ethernet service instance.

Use undo encapsulation to restore the default.

Syntax

encapsulation s-vid vlan-id

undo encapsulation

Default

No packet match criterion is configured for an Ethernet service instance.

Views

Ethernet service instance view

Predefined user roles

network-admin

Parameters

s-vid vlan-id: Matches packets with the specified outer VLAN ID. The value range for the vlan-id argument is 1 to 4094.

Usage guidelines

Do not configure the same match criterion for multiple Ethernet service instances on the same interface.

An Ethernet service instance can contain only one match criterion. To modify the match criterion, execute the undo encapsulation command to remove the criterion and then execute the encapsulation command. When you remove the match criterion in an Ethernet service instance, the mapping between the Ethernet service instance and the VSI is removed automatically.

Examples

# Configure Ethernet service instance 1 on Layer 2 Ethernet interface GigabitEthernet 3/1/1 to match packets that have an outer VLAN ID of 111.

undo flow-label

Default

The flow label feature is disabled.

Views

PW class view

Predefined user roles

network-admin

Parameters

both: Enables flow label sending and receiving capabilities on the local PE.

receive: Enables the flow label receiving capability on the local PE. The local PE can identify the flow label in a received packet and removes the flow label before forwarding the packet.

send: Enables the flow label sending capability on the local PE. The local PE adds a flow label before it adds a PW label to a packet during PW encapsulation.

Static: Configures the local and remote PEs to use configured flow label capabilities for dynamic PWs. If you do not specify this keyword, the local and remote PEs negotiate the flow label capabilities for dynamic PWs. This keyword does not take effect on static PWs, and static PWs always use configured flow label capabilities.

Usage guidelines

Packets carrying different types of traffic might be transmitted through the same PW and encapsulated with the same PW label. The P devices forward the traffic flows of a PW over the same path even if Equal Cost Multiple Paths (ECMPs) exist.

The L2VPN flow label feature can enable a P device to perform load sharing on packets based on the flow types.

After you configure this command, the P and PE devices process packets as follows:

· When the ingress PE encapsulates a packet, it adds a flow label before it adds a PW label.

· The P devices perform load sharing on packets based on the flow labels.

· The egress PE removes both the PW and flow labels from a packet before forwarding the packet.

If you do not specify the static keyword, the local and remote PEs negotiate the flow label capabilities by exchanging signaling protocol packets. The flow label feature does not take effect if the negotiation fails.

For two PEs to successfully negotiate the flow label capabilities, make sure one end has the sending capability and the other end has the receiving capability.

This command is applicable to static PWs, LDP PWs, BGP PWs, and BGP auto-discovery LDP PWs.

Examples

# Enable the flow label sending capability on the local PE.

Usage guidelines

If an L2VPN PW is carried by multiple equal-cost LDP LSPs, the PW evenly transmits packets through the LSPs. After you enable this feature, packets are transmitted through the LSPs in the proportion calculated based on the bandwidth of the egress interfaces.

This feature is available only when the public tunnels that carry a PW are LDP LSPs.

Parameters

ip-address: Specifies the LSR ID of the peer PE.

pw-id pw-id: Specifies a PW ID for the PW, in the range of 1 to 4294967295.

in-label label-value: Specifies the incoming label of the PW. The value range for the label-value argument is 16 to 1023.

out-label label-value: Specifies the outgoing label of the PW, in the range of 16 to 1048575.

hub: Specifies the PW as the hub link in the VSI. By default, a PW in the VSI enabled with the hub-spoke capability is a spoke link. This keyword is supported on CSPC-GE16XP4L-E, CSPC-GE24L-E, CSPC-GP24GE8XP2L-E, CSPEX, and CEPC cards.

no-split-horizon: Disables split horizon forwarding for the PW. By default, a PW must use the split horizon forwarding scheme to forward packets.

pw-class class-name: Specifies a PW class by its name, a case-sensitive string of 1 to 19 characters. You can specify a PW class to configure the PW data encapsulation type. If you do not specify a PW class, the PW data encapsulation type is VLAN.

tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-insensitive string of 1 to 19 characters. If you do not specify a tunnel policy, the PW uses the default tunnel policy.

Usage guidelines

A PE uses the PW Preferential Forwarding Status bit in LDP messages to advertise the local PWs' active/standby states. When the bit is set, it indicates that the local PW is in standby state. When the bit is cleared, it indicates that the local PW is in active state.

To create a static PW, you must specify the incoming and outgoing labels. To enter VSI static PW view of an existing static PW, you do not need to specify the incoming and outgoing labels.

The PW ID for a PW must be the same on the PEs at the ends of the PW.

On a PE, the LSR ID of the peer PE and the PW ID uniquely identify a PW. The peer LSR ID and PW ID combination of a PW must be unique among all VPLS PWs and cross-connect PWs.

If both the default PW ID in the default-pw-id command and a PW ID in the peer command are configured, the PW ID in the peer command is used. If only the default PW ID is configured, the default PW ID is used. If no default PW ID is configured, you must provide a PW ID in the peer command.

Examples

# Configure an LDP PW for VSI vpn1 and enter VSI LDP PW view: specify the peer PE address as 4.4.4.4, set the PW ID to 200, and disable split horizon forwarding for the PW.

Parameters

ethernet: Specifies the PW data encapsulation type as Ethernet.

vlan: Specifies the PW data encapsulation type as VLAN.

force-for-vpls: Forces VPLS to use and advertise the specified encapsulation type (Ethernet or VLAN). If you do not specify this keyword, the device always advertises the BGP-VPLS encapsulation type for VPLS BGP PW establishment.

Usage guidelines

When the PW data encapsulation type is Ethernet, the PE encapsulates packets forwarded between the AC and PW as follows:

· Traffic from the AC to the PW cannot carry the P-tag assigned by the service provider.

¡ If traffic from the AC has the P-tag, the PE removes the P-tag, and adds a PW label and an outer tag into the packet before forwarding it.

¡ If traffic from the AC does not have the P-tag, the PE adds a PW label and an outer tag into the packet before forwarding it.

· For traffic received from the PW:

¡ If the AC access mode is VLAN, the PE adds the P-tag and forwards the traffic through the AC.

¡ If the AC access mode is Ethernet, the PE directly forwards the traffic through the AC. The PE cannot modify or delete the P-tag for the traffic from the PW.

When the PW data encapsulation type is VLAN, the PE encapsulates packets forwarded between the AC and PW as follows:

· Traffic from the AC to the PW must carry the P-tag.

¡ If traffic from the AC has the P-tag, the PE performs one of the following operations:

- Keeps the P-tag when the peer PE does not require the ingress to modify the P-tag.

- Changes the P-tag to the expected value (which can be zero) when the peer PE requires the ingress to modify the P-tag. Then, the PE adds a PW label and an outer tag into the packet before forwarding it.

¡ If traffic from the AC does not have the P-tag, the PE performs one of the following operations:

- Adds a P-tag of 0 when the peer PE does not require the ingress to modify the P-tag.

- Adds the expected P-tag (which can be zero) when the peer PE requires the ingress to modify the P-tag. Then, the PE adds a PW label and an outer tag into the packet before forwarding it.

· For traffic received from the PW:

¡ If the AC access mode is VLAN, the PE modifies or keeps the P-tag and forwards the traffic through the AC.

¡ If the AC access mode is Ethernet, the PE removes the P-tag and forwards the traffic through the AC.

Use the force-for-vpls keyword only when you establish BGP PWs between Comware 7 devices and Comware 5 devices.

To ensure successful negotiation of the encapsulation type during VPLS BGP PW establishment between a Comware 7 device and a Comware 5 device, perform the following tasks:

· Configure the same encapsulation type on the devices.

· Specify the force-for-vpls keyword on the Comware 7 device if the Comware 5 device uses the Ethernet or VLAN encapsulation type.

To ensure successful PW establishment, configure the same encapsulation type for all devices in a VPLS instance.

Examples

# Configure the PW data encapsulation type as Ethernet.

network-admin

Parameters

route-distinguisher: Specifies an RD, a string of 3 to 21 characters. An RD can be in one 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.

Usage guidelines

This command is supported on CSPC-GE16XP4L-E, CSPC-GE24L-E, CSPC-GP24GE8XP2L-E, CSPEX, and CEPC cards.

VPLS uses RDs to differentiate the sites with the same site ID but in different VPNs.

BGP adds the configured RD before the site ID. The RD and the site ID uniquely identify a VPN site.

The configured RD applies to both BGP neighbor auto-discovery and VPLS label block advertisement.

You cannot configure the same RD for different BGP VSIs.

To modify an RD, execute the undo route-distinguisher command to remove the RD and then execute the route-distinguisher command.

Parameters

vpls-id: Specifies a VPLS ID, a string of 3 to 21 characters. You can specify a VPLS ID in one 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.

Usage guidelines

This command is supported on CSPC-GE16XP4L-E, CSPC-GE24L-E, CSPC-GP24GE8XP2L-E, CSPEX, and CEPC cards.

A VPLS ID uniquely identifies a VPLS instance. Two PEs must have the same VPLS ID to establish a PW.

VPLS IDs are used in the scenarios where BGP is used to find remote PEs and where FEC 129 LDP is used to establish PWs to the remote PEs.

The local PE advertises a BGP update that includes the configured VPLS ID as an extended community attribute to the remote PE. The remote PE compares the received VPLS ID with its own VPLS ID. If the two VPLS IDs are identical, the two PEs use FEC 129 LDP to establish a PW. If not, the PEs do not establish a PW.

To change a VPLS ID, execute the undo vpls-id command to remove the VPLS ID and then execute the vpls-id command.

Examples

# Configure the VPLS ID 100:1 for VSI aaa.

<Sysname> system-view

Parameters

vpn-target&<1-8>: Specifies a space-separated list of a maximum of eight route targets.

A route target is a string of 3 to 21 characters in one 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 route targets as both import targets and export targets. The both keyword is used when you do not specify any of both, export-extcommunity, and import-extcommunity.

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

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

all: Removes all route targets.

Usage guidelines

This command is supported on CSPC-GE16XP4L-E, CSPC-GE24L-E, CSPC-GP24GE8XP2L-E, CSPEX, and CEPC cards.

A local PE sets the route targets as export targets in BGP update messages when it advertises L2VPN information through the update messages to a remote peer. The peer uses its import targets to match the received export targets. If a match is found, the peer accepts the L2VPN information.

You can repeat the vpn-target command to configure multiple route targets for an auto-discovery VSI.

Examples

# Configure import route targets as 10:1 100:1 1000:1 and export route targets as 20:1 200:1 2000:1 for auto-discovery VSI aaa.

Predefined user roles

network-admin

Parameters

vsi-name: Specifies a name for the VSI, a case-sensitive string of 1 to 31 characters.

hub-spoke: Enables the hub-spoke capability for the VSI. If you do not specify this keyword, the VSI does not have the hub-spoke capability.

Usage guidelines

You can create multiple PWs for a VSI manually, or by using LDP or BGP.

Hub-spoke is a VPLS networking model that includes one hub site and multiple spoke sites. The spoke sites communicate with one another through the hub site.

For a hub-spoke network, you must enable the hub-spoke capability for the VSI. In the VSI with hub-spoke capability, the link (AC or PW) towards the hub site is the hub link and other links towards the branch sites are spoke links. By default, all links in the VSI are spoke links. You must specify an AC or a PW as the hub link in the VSI when you configure the xconnect vsi command or the peer command.

Parameters

vsi-name: Specifies the name of a VSI, a case-sensitive string of 1 to 31 characters.

access-mode: Specifies the AC access mode.

· When the AC is a Layer 3 interface or Layer 3 subinterface, the default settings are as follows:

¡ The default access mode is VLAN for VLAN interfaces and Ethernet for other Layer 3 interfaces.

¡ The default access mode is VLAN for Layer 3 subinterfaces.

· When the AC is an Ethernet service instance, the default access mode is VLAN.

ethernet: Specifies the access mode as Ethernet.

vlan: Specifies the access mode as VLAN.

hub: Specifies the AC as the hub link in the VSI. By default, an AC bound to a VSI enabled with hub-spoke capability is a spoke link in the VSI. This keyword is supported on CSPC-GE16XP4L-E, CSPC-GE24L-E, CSPC-GP24GE8XP2L-E, CSPEX, and CEPC cards.

leaf: Specifies the AC as a leaf AC in the E-Tree network. The AC acts as a root AC by default.

track track-entry-number&<1-3>: Specifies a space-separated list of up to three track entry numbers in the range of 1 to 1024. The AC is up only if a minimum of one associated track entry is in positive state.

Usage guidelines

After you bind a Layer 3 interface to a VSI, packets received from the interface are forwarded according to the MAC address table of the VSI. After you bind an Ethernet service instance to a VSI, packets matching the service instance are forwarded according to the MAC address table of the VSI.

The Ethernet service instance specified in this command must have a packet match criterion configured by the encapsulation command.

A subinterface operating as a hub link do not support the vlan-type dot1q vid second-dot1q command. For more information about the vlan-type dot1q vid second-dot1q command, see VLAN termination commands in Layer 2—LAN Switching Command Reference.

Table 27 shows the description and usage guidelines for the parameters in this command.

Table 27 Description and usage guidelines for command parameter

Parameter	Usage guidelines
access-mode { ethernet \| vlan }	The AC access mode determines how the device (PE) considers the VLAN tag in Ethernet frames received from the CE and how the PE forwards Ethernet frames to the CE. · VLAN access mode—Ethernet frames received from the CE must carry a VLAN tag in the Ethernet header. The PE considers the VLAN tag as a P-tag assigned by the service provider. Ethernet frames sent to the CE must also carry the P-tag. · Ethernet access mode—If Ethernet frames from the CE have a VLAN tag in the header, the PE considers it as a U-tag and ignores it. Ethernet frames sent to the CE do not carry the P-tag.
hub	To specify the AC as the hub link by using this command, you must first enable the hub-spoke capability for the specified VSI. By default, an AC is a spoke link in a VSI enabled with the hub-spoke capability.
leaf	Specify this keyword to configure the AC as a leaf AC. In an E-Tree network, a root AC can communicate with any root or leaf AC, while a leaf AC can communicate only with a root AC. Designate an AC as a root or leaf AC as needed. By default, an AC acts as a root AC in an E-Tree network.
