Parameters

interface-type interface-number: Specifies an interface by its type and number.

service-instance instance-id: Specifies an Ethernet service instance by its ID in the range of 1 to 4096.

access-mode: Specifies the access mode.

· When the AC is a VLAN interface or Layer 3 subinterface, the default access mode is VLAN.

· When the AC is a non-VLAN Layer 3 interface, the default access mode is Ethernet.

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

ethernet: Specifies the Ethernet access mode.

vlan: Specifies the VLAN access mode.

track track-entry-number&<1-15>: Specifies a space-separated list of up to 15 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 execute this command, packets received from the Layer 3 interface or those matching the Ethernet service instance are forwarded to the bound PW or another AC.

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

The access mode determines how the PE treats the VLAN tag in Ethernet frames received from the AC. It also determines how the PE forwards Ethernet frames to the AC.

· VLAN access mode—Ethernet frames received from the AC must carry a VLAN tag in the Ethernet header. The VLAN tag is called a P-tag assigned by the service provider. Ethernet frames sent to the AC must also carry the P-tag.

· Ethernet access mode—If Ethernet frames from the AC have a VLAN tag in the header, the VLAN tag is called a U-tag, and the PE ignores it. Ethernet frames sent to the AC do not carry the P-tag.

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 10 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 is determined by the link type of the interface.

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

Usage guidelines

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

To configure a backup static PW, you must specify the in-label and out-label. To configure a backup LDP PW, you do not need to specify the in-label and out-label.

The peer LSR ID and PW ID for a backup PW must be different from those for an existing VPLS PW or cross-connect PW.

PW redundancy and multi-segment PW are mutually exclusive with each other. If you have configured two PWs by using the peer command, you cannot configure a backup PW for the PWs by using the backup-peer command, and vice versa.

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.

Examples

# Configure a primary PW and a backup PW for cross-connect pw2pw in cross-connect group vpn2. The primary PW is destined to 6.6.6.6 and has a PW ID of 100. The backup PW is destined to 7.7.7.7 and has a PW ID of 200.

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

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

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 determined by the interface type.

Usage guidelines

A remote CCC connection is a static L2VPN connection that is manually created by specifying the incoming and outgoing labels on two PEs. A remote CCC connection does not need a public tunnel, but it requires configuring two static LSPs in opposite directions on each P device between the two PEs. CCC employs only one level of label to transfer packets. The static LSPs on the P devices transfer data only for the CCC connection.

This command must be configured on both the local and remote PEs to create a remote CCC connection. The outgoing label specified on a device must be the same as the incoming label specified on the next hop device.

After you create a remote CCC connection, you must execute the ac interface command to bind an interface or Ethernet service instance. The PE can forward packets from the interface or matching the Ethernet service instance to the remote CCC connection.

Use the out-interface keyword to specify the outgoing interface only on a point-to-point link. On other interfaces, for example, Layer 3 Ethernet interfaces or VLAN interfaces, you must use the nexthop keyword to specify the next hop IP address.

For the PEs to forward packets over a CCC connection, make sure the two PEs have the same CCC connection settings such as the encapsulation type.

Examples

# Create a remote CCC connection that has incoming label 100, outgoing label 200, and next hop 10.1.1.1, and uses PW class pwc1.

<Sysname> system-view

[Sysname] xconnect-group bbb

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-list [ only-tagged ]

encapsulation { default | untagged }

undo encapsulation

Default

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

Views

Predefined user roles

network-admin

Parameters

s-vid vlan-id-list: Matches packets with the specified outer VLAN IDs.

only-tagged: Matches tagged packets. If the outer VLAN is not the PVID, the matching result does not differ, whether or not you specify the only-tagged keyword. If the outer VLAN is the PVID, the matching result depends on whether or not the only-tagged keyword is specified.

· To match only PVID-tagged packets, specify the only-tagged keyword.

· To match both untagged packets and PVID-tagged packets, do not specify the only-tagged keyword.

NOTE:

The only-tagged keyword is supported only in R3608 and later.

s-vid vlan-id-list c-vid vlan-id-list: Matches packets with the specified outer VLAN IDs and the specified inner VLAN IDs.

· The vlan-id argument specifies a VLAN ID in the range of 1 to 4094.

· The vlan-id-list argument specifies a space-separated list of up to eight VLAN items. Each item specifies a VLAN ID or a range of VLAN IDs in the format of start-VLAN-ID to end-VLAN-ID. The value range for VLAN IDs is 1 to 4094.

· all: Specifies all VLAN IDs.

default: Matches packets that do not match any other Ethernet service instances on the interface. On an interface, you can configure this criterion only in one Ethernet service instance. The Ethernet service instance matches all packets if it is the only instance on the interface.

untagged: Matches any packets that do not have a VLAN tag.

Usage guidelines

To configure match criteria for multiple Ethernet service instances on the same interface, follow these restrictions and guidelines:

· Two match criteria configured by the encapsulation s-vid command must not have the same or overlapped outer VLAN IDs.

· Two match criteria configured by the encapsulation s-vid c-vid command cannot have overlapped outer or inner VLAN IDs. However, they can have totally the same outer or inner VLAN IDs if they have totally different inner or outer VLAN IDs.

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 cross-connect is removed automatically.

Examples

# Configure Ethernet service instance 1 on HundredGigE 1/0/1 to match packets that have an outer VLAN ID of 111 and an inner VLAN ID of 20 or from 30 to 40.

Parameters

size: Specifies an MTU value. The value range for this argument is 300 to 65535.

Usage guidelines

The specified MTU applies to all PWs established in the cross-connect view or the auto-discovery cross-connect group view.

The MTU specifies the maximum packet length, including the PW label and network layer packet.

When PW MTU negotiation is enabled, you can establish an LDP or BGP PW between two PEs only when you configure the same PW MTU on the two PEs. When PW MTU negotiation is disabled, you can establish an LDP or BGP PW between two PEs even if you configure different PW MTUs on the two PEs.

Examples

# Set the MTU to 1400 bytes for cross-connect ac2pw in cross-connect group vpn1.

<Sysname> system-view

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.

ignore-standby-state: Ignores the PW active/standby status bit received from the remote PE. If you do not specify this keyword, the local PE does not ignore the PW active/standby status bit received from the remote PE. This keyword is applicable only to LDP PWs.

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.

admin: Specifies the PW as an administration PW. If you do not specify this keyword, the PW is a service PW.

NOTE:

The admin keyword is supported only in R3608 and later.

tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 126 characters. If you do not specify a tunnel policy, the default tunnel policy is used.

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.

In independent mode, a PE considers the status bits received from the remote PEs when it selects the forwarding PW among the set of redundant PWs. If you specify the ignore-standby-state keyword, the PE ignores the status bits received from the remote PEs and selects the forwarding PW using its own local rule.

In master/slave mode, a slave PE selects the forwarding PW among the set of redundant PWs based on the status bit received from the remote PEs. If you specify the ignore-standby-state keyword, the PE ignores the status bit received from the remote PEs and uses the primary PW to forward packets as long as the primary PW is up.

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

If you do not specify the incoming and outgoing labels when you create a new PW, LDP is used to create the PW.

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.

Examples

# Configure an LDP PW destined for 4.4.4.4 for cross-connect pw2pw in cross-connect group vpn1 and enter cross-connect PW view. The PW ID is 200.

Parameters

independent: Specifies the independent PW redundancy operation mode.

master: Specifies the master/slave PW redundancy operation mode and uses the local PE as the master node.

Usage guidelines

This command is applicable only to LDP PWs.

LDP PWs support the independent and master/slave PW redundancy operation modes.

· Independent mode—The two PEs of a PW use LDP to advertise their respective PW active/standby state to each other. A PW can forward traffic only when it is up and active at both ends of the PW. In this mode, make sure both PEs of a PW use the independent PW redundancy operation mode.

· Master/slave mode—One PE of a PW operates as the master node and the other PE operates as the slave node. The master PE determines the PW active/standby state and then uses LDP to advertise the PW state to the slave PE. The slave PE uses the same PW state as the master PE based on the information received from the master PE. In this way, the master and slave PEs for the set of redundant PWs can use the same active PW to forward user packets.

A slave node does not advertise the PW active/standby state to the master node, and the master node ignores the PW active/standby state received from the slave nodes.

Examples

# In cross-connect view of cross-connect pw2pw in cross-connect group vpn1, specify the master/slave PW redundancy operation mode and use the local PE as the master node.

Parameters

ethernet: Specifies the PW data encapsulation type as Ethernet.

vlan: Specifies the PW data encapsulation type as VLAN.

Usage guidelines

When the PW data encapsulation type is Ethernet, P-tag is not transferred on a PW.

· For a packet from a CE:

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

¡ If the packet contains no P-tag, the PE directly adds a PW label and an outer tag into the packet before forwarding it.

· For a packet to a CE:

¡ If the access mode is configured as VLAN by using the ac interface command, the PE adds a P-tag into the packet before sending it to the CE.

¡ If the access mode is configured as Ethernet by using the ac interface command, the PE directly sends the packet to the CE.

You cannot rewrite or remove existing tags.

When the PW data encapsulation type is VLAN, packets transmitted over a PW must carry a P-tag.

· For a packet from a CE:

¡ If the peer PE does not require the ingress to rewrite the P-tag, the PE keeps the P-tag unchanged for the packet, and then encapsulates the packet. If the packet contains no P-tag, the PE adds a null label (the label value is 0) into the packet, and then encapsulates the packet.

¡ If the peer PE requires the ingress to rewrite the P-tag, the PE changes the P-tag to the expected VLAN tag (the tag value might be 0), and then adds a PW label and an outer tag into the packet. If the packet contains no P-tag, the PE adds a VLAN tag expected by the peer PE (the tag value might be 0), and then adds a PW label and an outer tag into the packet.

· For a packet to a CE:

¡ If the access mode is configured as VLAN by using the ac interface command, the PE rewrites or retains the P-tag before forwarding the packet.

¡ If the access mode is configured as Ethernet by using the ac interface command, the PE removes the P-tag before forwarding the packet.

Parameters

interface interface-type interface-number: Specifies a Layer 2 interface or a Layer 3 interface by its type and number.

service-instance instance-id: Specifies an Ethernet service instance on the specified Layer 2 interface. The value range for the instance-id argument is 1 to 4096.

Usage guidelines

If you do not specify any parameters, this command clears packet statistics for all ACs.

If you specify a Layer 3 interface, you cannot specify the service-instance instance-id option. If you specify a Layer 2 interface, you must specify the service-instance instance-id option.

Examples

# Clear packet statistics on Layer 3 interface HundredGigE 1/0/1.

<Sysname> reset l2vpn statistics ac interface hundredgige 1/0/1

revertive

Use revertive to specify the switchover mode and set the switchover wait time.

Use undo revertive to restore the default.

Syntax

revertive { wtr wtr-time | never }

undo revertive { wtr | never }

Default

The switchover mode is revertive and the switchover wait time is 0 seconds. When the primary PW recovers, traffic is immediately switched from the backup PW to the primary PW.

Parameters

wtr wtr-time: Specifies the switchover mode as revertive and specifies the wait time in the range of 0 to 3600 seconds. When the primary PW recovers, the PE waits for the specified time before switching traffic from the backup PW to the primary PW.

never: Specifies the switchover mode as non-revertive. After the primary PW recovers, traffic is not switched from the backup PW to the primary PW.

Examples

# Specify the revertive mode and set the switchover wait time to 120 seconds for cross-connect ac2pw in cross-connect group vpn1.

<Sysname> system-view

[Sysname] xconnect-group vpn1

[Sysname-xcg-vpn1] connection ac2pw

route-distinguisher

Use route-distinguisher to configure a route distinguisher (RD) for a BGP cross-connect group.

Use undo route-distinguisher to restore the default.

NOTE:

This command is supported only in R3608 and later.

Syntax

route-distinguisher route-distinguisher

undo route-distinguisher

Default

No RD is configured for a BGP cross-connect group.

Views

Auto-discovery cross-connect group view

Predefined user roles

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

MPLS L2VPN 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.

You cannot configure the same RD for different BGP cross-connect groups.

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

Examples

# Configure the RD 22:2 for BGP cross-connect group bbb.

<Sysname> system-view

[Sysname] xconnect-group bbb

[Sysname-xcg-bbb] auto-discovery bgp

[Sysname-xcg-bbb-auto] route-distinguisher 22:2

rr-filter

Use rr-filter to create a route reflector (RR) reflection policy.

Use undo rr-filter to restore the default.

NOTE:

This command is supported only in R3608 and later.

Syntax

rr-filter ext-comm-list-number

undo rr-filter

Default

An RR does not filter reflected L2VPN information.

Views

BGP L2VPN address family view

Predefined user roles

network-admin

Parameters

ext-comm-list-number: Specifies an extended community list number in the range of 1 to 65535.

Usage guidelines

After this command is executed, only the L2VPN information that is permitted by the specified extended community list is reflected.

By configuring different RR reflection policies on RRs in a cluster, you can implement load balancing among the RRs.

For more information about extended community lists, see Layer 3—IP Routing Configuration Guide.

Examples

# Configure the RR to reflect only the BGP L2VPN information that is permitted by extended community list 10.

<Sysname> system-view

Usage guidelines

After you disable a cross-connect group, all cross-connects in the group cannot provide L2VPN services.

Use the shutdown command when you want to temporarily disable L2VPN. When a cross-connect group is disabled, you can still configure the cross-connect group. After the configuration, use the undo shutdown command to enable the cross-connect group. The cross-connect group will provide L2VPN services using the new settings.

Examples

# Disable cross-connect group vpn2.

<Sysname> system-view

[Sysname] xconnect-group vpn2

[Sysname-xcg-vpn2] shutdown
