Parameters
bgp: Enables the VSI to automatically discover neighbors through BGP.
Usage guidelines
In auto-discovery VSI view, you can configure parameters such as the local site, VPLS ID, and route targets for BGP, so the local PE can use BGP to discover remote PEs.
You can use the signaling-protocol command to specify the signaling protocol, LDP or BGP, to establish PWs to the remote PEs found by BGP.
Examples
# Enable VSI aaa to automatically discover neighbors through BGP and enter auto-discovery VSI view.
<Sysname> system-view
[Sysname] vsi aaa
[Sysname-vsi-aaa] auto-discovery bgp
[Sysname-vsi-aaa-auto]

Usage guidelines
The control word field is between the MPLS label stack and the Layer 2 data. It carries extra control information about the Layer 2 frame, for example, the sequence number. The control word feature has the following functions:
· Avoids fragment disorder. In multi-path forwarding, fragments received might be disordered. You can configure the control word feature on the device, so the device can reorder the fragments according to the sequence number carried in the control word field.
· Identifies the original payload length for packets that include padding.
For packets transmitted on a PW to carry the control word field, you must enable the control word feature on both PEs of the PW.
Examples
# Enable control word for PW class pw100.
<Sysname> system-view
[Sysname] pw-class pw100
[Sysname-pw-pw100] control-word enable

Parameters
peer ip-address: Displays information about PW labels advertised by a peer PE through LDP. The ip-address argument specifies the LSR ID of the peer PE. If you do not specify a peer PE, this command displays information about LDP PW labels advertised by all peer PEs.
pw-id pw-id: Displays FEC 128 LDP PW label information for the PW specified by its PW ID. The PW ID is in the range of 4294967295. If you specify the peer ip-address option without the pw-id pw-id option, this command displays all LDP PW label information advertised by the specified peer PE.
vpls-id vpls-id: Displays FEC 129 LDP PW label information for the VPLS instance specified by its ID, which is 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, 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, such as 65536:1. In this format, the minimum value of the AS number is 65536.
vsi vsi-name: Displays LDP PW label information for the VSI specified by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VSI, this command displays LDP PW label information for all VSIs.
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.

Use encapsulation to configure a packet match criterion for an Ethernet service instance.
Use undo encapsulation to remove a packet match criterion from an Ethernet service instance.
Syntax

encapsulation s-vid vlan-id [ only-tagged ]
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
default: Matches all incoming packets.
tagged: Matches tagged packets.
untagged: Matches untagged packets.
s-vid vlan-id: Matches packets with a specific outer VLAN ID. The vlan-id argument specifies a VLAN ID in the range of 1 to 4094.
only-tagged: Matches only 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.
Usage guidelines
You can configure only one of the following match criteria for an Ethernet service instance:
· Match all incoming packets.
· Match incoming packets with any VLAN ID or no VLAN ID.
· Match incoming packets with a specific outer VLAN ID.
To match incoming packets with VLAN IDs on an interface, you must first create the VLANs, and then assign the interface to the VLANs.
The match criterion configured for different Ethernet service instances on an interface must be different.
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 FortyGigE 1/1/1 to match packets that have an outer VLAN ID of 111.

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, in the range of 16 to 1023.
out-label label-value: Specifies the outgoing label of the PW, in the range of 16 to 1023.
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 type and control word. If you do not specify a PW class, the PW type is VLAN and the PW does not support control word.
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
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, and must be different than those of any VPLS PWs or cross-connect PWs.
If both a 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 a 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 type as Ethernet.
vlan: Specifies the PW type as VLAN.
Usage guidelines
When the PW 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 (configured by the xconnect vsi command) 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 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 (configured by the xconnect vsi command) 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.

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 that reside in different VPNs and have the same site ID.
BGP adds the configured RD before the site ID. The RD and the site ID uniquely identify a VPN site.
The configure RD applies to both BGP neighbor auto-discovery and VPLS label block advertisement.
You cannot configure the same RD for different BGP VSIs.
To change an RD, you must remove the RD and then configure it again.

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, 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, such as 65536:1. In this format, the minimum value of the AS number is 65536.
Usage guidelines
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 scenario where BGP is used to find remote PEs and 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, you must remove the VPLS ID and then configure it again.
Examples
# Configure the VPLS ID 100:1 for VSI aaa.
<Sysname> system-view
[Sysname] vsi aaa

Predefined user roles
network-admin
Parameters
vpn-target&<1-8>: Specifies a space-separated list of up to 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
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.
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.

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. By default, the access mode is VLAN.
ethernet: Specifies the access mode as Ethernet.
vlan: Specifies the access mode as VLAN.
Usage guidelines
After you bind an Ethernet service instance on a Layer 2 interface to a VSI, the Ethernet service instance matches packets received on the interface. The matching packets are forwarded according to the MAC address table of the VSI.
The access mode determines how the PE considers the VLAN tag in Ethernet frames received from the AC and 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 PE considers the VLAN tag as 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 PE considers it as a U-tag and ignores it. Ethernet frames sent to the AC do not carry the P-tag.
