Parameters
value: Default value for the local preference, in the range of 0 to 4294967295. A greater value represents a higher priority.
Description
Use the default local-preference command to set the default value of the local preference.
Use the undo default local-preference command to restore the default.
By default, the default value of the local preference is 100.
Examples
# Devices A and B are connected to the outside AS. In BGP-VPNv4 subaddress family view of Device B, set the default local preference of Device B to 180, so that when a destination in the outside AS can be reached through both A and B, the BGP VPN-IPv4 route going through B to the destination is preferred.

Parameters
domain-id: OSPF domain ID, which can be in one of the following formats:
· Integer, in the range of 0 to 4294967295. For example, 1.
· Dotted decimal notation. For example, 0.0.0.1.
· Dotted decimal notation:16-bit user-defined number, in the range of 0 to 65535. For example, 0.0.0.1:512.
secondary: Uses the domain ID as secondary. With this keyword not specified, the domain ID configured is primary.
Description
Use the domain-id command to configure an OSPF domain ID.
Use the undo domain-id command to restore the default.
By default, the OSPF domain ID is 0.
With no parameter specified, the undo domain-id command deletes all domain IDs.
Usually, routes injected from PEs are advertised as External-LSAs. However, routes to different destinations in the same OSPF domain must be advertised as Type-3 LSAs. Therefore, you must use the same domain ID for an OSPF domain.

Parameters
group-name: Name of the peer group, a string of 1 to 47 characters.
ip-address: IP address of the peer.
both: Supports sending and receiving Route-refresh messages with ORF information.
receive: Supports receiving Route-refresh messages with ORF information.
send: Supports sending Route-refresh messages with ORF information.
Description
Use the peer capability-advertise orf ip-prefix command to enable the ORF capability for a BGP peer or peer group.
Use the undo peer capability-advertise orf ip-prefix command to disable the ORF capability for a BGP peer or peer group.
By default, the ORF capability is disabled for a BGP peer or peer group.
With the ORF capability enabled, the local BGP router negotiates the ORF capability with the BGP peer through Open messages. After the negotiation succeeds, the BGP router can process Route-refresh messages with the standard ORF information from the peer or send Route-refresh messages with the standard ORF information to the peer.
If you disable the ORF capability, the local BGP router does not negotiate the ORF capability with the specified peer or peer group.

Parameters
group-name: Name of the peer group, a case-sensitive string of 1 to 47 characters.
peer-address: IP address of the peer.
vpn-instance-name: Name of the VPN instance, a case-sensitive string of 1 to 31 characters.
Description
Use the peer vpn-instance enable command to activate a nested VPN peer or peer group and enable the capability of exchanging BGP-VPNv4 routes with the peer or peer group.
Use the undo peer vpn-instance enable command to disable the capability of exchanging BGP-VPNv4 routes with a nested VPN peer or peer group.
By default, nested VPN peers/peer groups can exchange only IPv4 routes; they cannot exchange BGP-VPNv4 routes.
This configuration takes effect only after the nested VPN function is enabled.
Before specifying a nested VPN peer or peer group, be sure to configure the corresponding CE peer or peer group by using the peer as-number command in BGP-VPN instance view.
Deleting the VPN instance to which a peer belongs will also delete the configuration of this command.

Parameters
cluster-id: Cluster ID of the route reflector (RR), in the range of 1 to 4294967295.
ip-address: IP address of the peer, which is to be used as the cluster ID of the RR.
Description
Use the reflector cluster-id command to specify a cluster ID for an RR.
Use the undo reflector cluster-id command to remove the cluster ID.
By default, the cluster ID is the router ID of an RR in the cluster.
Typically, a cluster contains only one RR, in which case the router ID of the RR is used for identifying the cluster. Setting multiple RRs can improve the network reliability. When more than one RR exists in a cluster, use the reflector cluster-id command to configure the same cluster ID for all RRs in the cluster.

Parameters
route-distinguisher: Route distinguisher (RD) for the VPN instance, a string of 3 to 21 characters in one of the following three 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 minimum value of the AS number is 65536. For example, 65536:1.
Description
Use the route-distinguisher command to configure a route distinguisher (RD) for a VPN instance.
An RD is used to create the routing and FIB of a VPN. By prefixing an RD to an IPv4 prefix, you get a VPN IPv4 prefix unique globally.
|
NOTE: · No RD is configured by default; you must configure an RD for each VPN instance. · A VPN instance takes effect only after you configure an RD for it. · Once you configure an RD for a VPN, you cannot remove the association. · You cannot change an RD directly; you can only delete the VPN instance, and then re-create the VPN instance and re-configure a new RD. |
Examples
# Configure the RD of VPN instance vpn1.

View

Default level
2: System level
Parameters
tag-value: External route tag of the imported VPN routes, in the range of 0 to 4294967295.
Description
Use the route-tag command to configure the external route tag for imported VPN routes.
Use the undo route-tag command to restore the default.
By default, if BGP is running in the MPLS backbone and the BGP’s AS number is not greater than 65535, the first two octets of the default external route tag is always 0xD000 and the last two octets is the AS number of the local BGP. For example, if the local BGP AS number is 100, the default value of the external route tag is 3489661028, which equals the decimal value of 0xD0000000 (3489660928) + 100. If the AS number is greater than 65535, the default external route tag is 0.
If PE-CE routing protocol is OSPF, the local PE redistributes the BGP VPNv4 routes received from the peer PE into the OSPF routing table, and advertises these routes to the locally connected CE through OSPF. If the routes are advertised to the CE through Type 5 or 7 LSAs, Type 5/7 LSAs must contain the external route tag. An external route tag can be configured by different commands and has different priorities. The following lists the commands used to configure the external route tag (in the descending order of tag priority):
· import-route
· route-tag
· default tag
The external route tag is used to avoid routing loops. If the external route tag carried in a Type 5 or 7 LSA received by a PE is the same as the locally configured external route tag, the PE neglects the LSA in route calculation to avoid routing loops.
Note the following issues:
· H3C recommends configuring the same external route tag for PEs in the same AS.
· An external route tag is not transferred in any BGP extended community attribute. It is only locally significant and takes effect only on the PEs that receive BGP routes and generate OSPF Type 5 or 7 LSAs.
· You can configure the same external route tag for different OSPF processes.
Related commands: import-route and default (Layer 3—IP Routing Command Reference).

# Set the external route tag of the imported VPN routes to 100 for OSPF process 100.

Default level
2: System level
Parameters
number: Specifies the maximum number of routes supported, in the range of 1 to 1048576.
warn-threshold: Specifies a threshold for warning, in the range of 1 to 100, in percentages. When the percentage of the number of existing routes to the maximum number of routes supported exceeds the specified threshold, the system gives an alarm message but still allows new routes. If the number of routes in the VPN instance reaches the maximum supported, no more routes are added.
simply-alert: Specifies that when the number of routes exceeds the maximum number of routes supported, the system still accepts routes but generates a system log (Syslog) message.
Description
Use the routing-table limit command to limit the maximum number of routes in a VPN instance, an IPv4 VPN, or an IPv6 VPN, preventing too many routes from being accepted by a PE.
Use the undo routing-table limit command to restore the default.
A limit configured in VPN instance view is applicable to both the IPv4 VPN and the IPv6 VPN.
A limit configured in IPv4 VPN view is applicable to only the IPv4 VPN.
A limit configured in IPv6 VPN view is applicable to only the IPv6 VPN.
A limit configured in IPv4 VPN view or IPv6 VPN view takes precedence over that configured in VPN instance view. If you configure a limit in both IPv4 VPN view (or IPv6 VPN view) and VPN instance view, the limit configured in IPv4 VPN view (or IPv6 VPN view) is applied to the IPv4 VPN (or IPv6 VPN).

Description
Use the sham link command to configure a sham link.
Use the undo sham link command with no optional keyword to remove a sham link.
Use the undo sham link command with optional keywords to restore the defaults of the parameters for a sham link.
If two PEs belong to the same AS and a backdoor link is present, a sham link can be established between them.
For plain text authentication, the default authentication key type is plain. For authentication using MD5 algorithm or HMAC-MD5 algorithm, the default authentication key type is cipher.

tnl-policy (VPN instance view/IPv4 VPN view/IPv6 VPN view)
Syntax
tnl-policy tunnel-policy-name
undo tnl-policy
View
VPN instance view, IPv4 VPN view, IPv6 VPN view
Default level
2: System level
Parameters
tunnel-policy-name: Name of the tunneling policy for the VPN instance, a string of 1 to 19 characters.
Description
Use the tnl-policy command to associate the current VPN instance with a tunneling policy.
Use the undo tnl-policy command to remove the association.
If a VPN instance is not associated with any tunneling policy or the associated tunneling policy is not configured, the VPN instance selects tunnels according to the default tunneling policy. The default tunneling policy selects only one tunnel (no load balancing) in this order: LSP tunnel, CR-LSP tunnel.
A tunneling policy specified in VPN instance view is applicable to both the IPv4 VPN and the IPv6 VPN.
A tunneling policy specified in IPv4 VPN view is applicable to only the IPv4 VPN.
A tunneling policy specified in IPv6 VPN view is applicable to only the IPv6 VPN.
A tunneling policy specified in IPv4 VPN view or IPv6 VPN view takes precedence over that specified in VPN instance view. If you specify a tunneling policy in both IPv4 VPN view (or IPv6 VPN view) and VPN instance view, the tunneling policy specified in IPv4 VPN view (or IPv6 VPN view) is applied to the IPv4 VPN (or IPv6 VPN).

tunnel select-seq
Syntax
tunnel select-seq { cr-lsp | lsp } * load-balance-number number
undo tunnel select-seq
View
Tunneling policy view
Default level
2: System level
Parameters
cr-lsp: Specifies CR-LSP tunnels.
lsp: Specifies LSP tunnels.
load-balance-number number: Specifies the number of tunnels for load balancing.
Description
Use the tunnel select-seq command to configure the preference order for tunnel selection and the number of tunnels for load balancing.
Use the undo tunnel select-seq command to restore the default.
By default, the tunnel selection preference order is: LSP tunnels, CR-LSP tunnels, and the number of tunnels for load balancing is 1—no load balancing.
Only tunnels of the types specified in the tunnel select-seq command can be used.
A tunnel type closer to the select-seq keyword has a higher priority.
The number of tunnels for load balancing refers to the number of tunnels that an application can use.
CR-LSP tunnels are preferred by the following order: CR-LSPs configured with ACLs, CR-LSPs bound with VPN, ordinary CR-LSPs. These three types of CR-LSPs are mutually exclusive. Only one type of the three is selected at a time.
Examples
# Define a tunneling policy, specifying that only CR-LSP tunnels can be used and setting the number of tunnels for load balancing to 2.

Parameters
None
Description
Use the vpn popgo command on an egress PE to specify the VPN label processing mode as POPGO forwarding, which will pop the label and then search for the outbound interface according to the label to forward the traffic.
Use the undo vpn popgo command to restore the default.
By default, the VPN label processing mode of an egress PE is POP forwarding, which will pop the label and then search the FIB table to find the outbound interface to forward the traffic.
|
NOTE: After you execute the vpn popgo or undo vpn popgo command on the router, reboot the router to make the specified label processing mode take effect. You can use the display vpn label operation command to view the current VPN label processing mode. |

undo vpn-target { all | vpn-target&<1-8> [ both | export-extcommunity | import-extcommunity ] }
View
VPN instance view, IPv4 VPN view, IPv6 VPN view
Default level
2: System level
Parameters
vpn-target&<1-8>: Adds a VPN target extended community attribute to the import VPN target extended community attribute list (Import Target) or export VPN target extended community attribute list (Export Target). &<1-8> means that you can add up to eight 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. 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 not be less than 65536. For example, 65536:1.
both: Uses the specified VPN target value as both an import target and an export target . 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 target as an export target.
import-extcommunity: Uses the specified VPN target as an import target.
all: Removes all VPN targets.
Description
Use the vpn-target command to configure VPN targets for a VPN instance, an IPv4 VPN, or an IPv6 VPN.
Use the undo vpn-target command to remove the specified or all VPN targets of a VPN instance, an IPv4 VPN, or an IPv6 VPN.
By default, no VPN targets are configured and you must configure VPN targets when creating a VPN instance, an IPv4 VPN, or an IPv6 VPN.
VPN targets configured in VPN instance view is applicable to both the IPv4 VPN and the IPv6 VPN.
VPN targets configured in IPv4 VPN view is applicable to only the IPv4 VPN.
VPN targets configured in IPv6 VPN view is applicable to only the IPv6 VPN.
VPN targets configured in IPv4 VPN view or IPv6 VPN view takes precedence over that configured in VPN instance view. If you configure VPN targets in both IPv4 VPN view (or IPv6 VPN view) and VPN instance view, those configured in IPv4 VPN view (or IPv6 VPN view) are applied to the IPv4 VPN (or IPv6 VPN).
