Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If no VPN instance is specified, the command displays BGP VPNv4 routing information advertised to or received from the specified BGP peer on the public network.

ip-address: Specifies a peer by its IP address.

advertised-routes: Displays routing information advertised to the specified peer.

received-routes: Displays routing information received from the specified peer.

network-address: Specifies the IP address of the destination network.

mask: Specifies the mask of the destination network, in dotted decimal notation.

mask-length: Specifies a mask length in the range of 0 to 32.

statistics: Displays route statistics.

Usage guidelines

If none of network-address, mask, and mask-length are specified, the command displays all BGP VPNv4 routing information advertised to or received from the specified BGP peer.

If the network-address argument is specified without mask or mask-length, the system ANDs the network address with the mask of a route. If the result matches the network address of the route, the command displays information about the route.

If network-address mask or network-address mask-length is specified, the command displays information about the route that exactly matches the specified address and mask (or mask length).

Predefined user roles

network-admin

mdc-admin

Parameters

domain-id: OSPF domain ID, in one of these 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: Specifies a secondary domain ID. Without this keyword, the command specifies a primary domain ID.

Usage guidelines

When you redistribute OSPF routes into BGP, BGP adds the configured OSPF domain ID to the redistributed BGP VPN routes as a BGP extended community attribute and advertises the routes to the BGP peer. When you redistribute the BGP VPN routes into OSPF on the BGP peer, OSPF uses the domain ID to determine whether the routes belong to the same OSPF routing domain. If yes and the routes are intra-area routes, OSPF advertises these routes in Summary LSAs (Type 3). If yes but the routes are not intra-area routes, OSPF advertises these routes in AS External LSAs (Type 5) or NSSA External LSAs (Type 7). If not, OSPF advertises these routes in Type 5 or Type 7 LSAs.

With no parameter specified, the undo domain-id command deletes all domain IDs.

Examples

# Configure an OSPF domain ID.

Views

User view

Predefined user roles

Parameters

ip-address: Soft resets the BGP VPNv4 connection with the BGP peer identified by this IP address.

all: Soft resets all BGP VPNv4 connections.

external: Soft resets EBGP VPNv4 connections.

group group-name: Soft resets BGP VPNv4 connections with the BGP peer group identified by this name, a case-sensitive string of 1 to 47 characters.

internal: Soft resets IBGP VPNv4 connections.

export: Soft resets outbound EBGP VPNv4 connections.

import: Soft resets inbound EBGP VPNv6 connections.

vpn-instance vpn-instance-name: Soft resets BGP VPNv4 connections for the VPN instance specified by its name, a case-sensitive string of 1 to 31 characters. If no VPN instance is specified, this command soft resets BGP VPNv4 connections for the public network.

Usage guidelines

Soft reset can update BGP VPNv4 routing information without breaking down BGP neighbor relationships.

You can apply a new route selection policy by executing this command. If you execute this command with the export keyword, BGP filters advertised routing information based on the new policy and sends the matching routes to the BGP peer. If you execute this command with the import keyword, BGP advertises a route-refresh message to the peer so the peer re-advertises its routing information. After receiving the routing information from the peer, BGP filters the routing information by using the new policy.

This command requires that both the local router and the peer support route refresh.

If the peer keep-all-routes command is configured, the refresh bgp vpnv4 import command does not take effect.

Examples

# Soft reset all inbound BGP VPNv4 connections for the public network.

<Sysname> refresh bgp all import vpnv4

Views

VPN instance view

Predefined user roles

network-admin

mdc-admin

Parameters

vlan-id: Specifies a reserved VLAN by its VLAN ID in the range of 1 to 4094.

Usage guidelines

The reserved VLAN of a VPN instance provides resources for the VPN instance to complete packet forwarding.

A common VLAN, including a default VLAN, a VLAN created by vlan, and a dynamically learned VLAN, cannot be specified as a reserved VLAN. After you specify a VLAN as the reserved VLAN of a VPN instance, the VLAN cannot be created by the vlan command, or dynamically learned.

Reserved VLANs specified for VPN instances must be different.

The reserved VLAN configuration takes effect only when the system is operating in standard mode. For more information about system operating modes, see Fundamentals Configuration Guide.

When the system is operating in standard mode, you must configure a reserved VLAN for a created VPN instance in the following cases:

· The VPN instance is connected to no CEs.

· There is no need to configure the multicast VPN function for the VPN instance.

· There is no need to bind the VPN instance to an IP tunnel.

When the system is operating in standard mode, if a VPN instance is not configured with a reserved VLAN, you cannot configure URPF on the private network VLAN interface bound to the VPN instance.

Examples

# Specify VLAN 100 as the reserved VLAN of VPN instance vpn1.

Parameters

route-distinguisher: RD for the VPN instance, a string of 3 to 21 characters in one of these 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.

Usage guidelines

RDs enable VPNs to use the same address space. An RD and an IPv4 prefix comprise a unique VPN IPv4 prefix.

To change the RD of a VPN instance, you must delete the RD with the undo route-distinguisher command, and then use the route-distinguisher command to configure a new RD.

Examples

# Configure RD 22:1 for VPN instance vpn1.

<Sysname> system-view

[Sysname] ip vpn-instance vpn1

[Sysname-vpn-instance-vpn1] route-distinguisher 22:1

route-tag

Use route-tag to configure an external route tag for redistributed VPN routes.

Use undo route-tag to restore the default.

Syntax

route-tag tag-value

undo route-tag

Default

If the AS number is not greater than 65535, the first two octets of the default external route tag are 0xD000 and the last two octets is the local AS number. For example, if the local BGP AS number is 100, the default value of the external route tag is 3489661028. If the AS number is greater than 65535, the default external route tag is 0.

Parameters

tag-value: External route tag for redistributed VPN routes, in the range of 0 to 4294967295.

Usage guidelines

If the PE-CE routing protocol is OSPF, the PE redistributes 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 in 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

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 ignores the LSA in route calculation to avoid routing loops.

H3C recommends configuring the same external route tag for PEs in the same area.

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.

Examples

# In OSPF process 100, set the external route tag for redistributed VPN routes to 100.

mdc-admin

Parameters

number: Specifies the maximum number of routes. The value range depends on the system operating mode. For more information about system operating modes, see Fundamentals Configuration Guide.

warn-threshold: Specifies a warning threshold, in the range of 1 to 100 in percentage. When the percentage of the number of existing routes to the maximum number of routes exceeds the specified threshold, the system gives an alarm message but still allows new routes. If routes in the VPN instance reach the maximum, no more routes are added.

simply-alert: Specifies that when routes exceeds the maximum number, the system still accepts routes but generates a system log message.

Usage guidelines

A limit configured in VPN instance view applies to both the IPv4 VPN and the IPv6 VPN.

A limit configured in IPv4 VPN view or IPv6 VPN view applies to only the IPv4 VPN or the IPv6 VPN.

IPv4/IPv6 VPN prefers the limit configured in IPv4/IPv6 VPN view over the limit configured in VPN instance view.

Predefined user roles

network-admin

mdc-admin

Parameters

tunnel-policy-name: Specifies a tunnel policy by its name, a case-insensitive string of 1 to 19 characters.

Usage guidelines

The VPN instance uses the specified tunnel policy to select tunnels for traffic.

If a VPN instance is not associated with any tunnel policy or the associated tunnel policy is not configured, the VPN instance selects tunnels according to the default tunnel policy. The default tunnel policy selects only one tunnel in this order: LSP tunnel, GRE tunnel, CR-LSP tunnel.

A tunnel policy specified in VPN instance view is applicable to both the IPv4 VPN and the IPv6 VPN.

A tunnel policy specified in IPv4 VPN view or IPv6 VPN view is applicable to only the IPv4 VPN or IPv6 VPN.

IPv4/IPv6 VPN prefers the tunnel policy specified in IPv4/IPv6 VPN view over the tunnel policy specified in VPN instance view.

Examples

# Associate VPN instance vpn1 with tunnel policy po1.

vpn popgo

Use vpn popgo to specify the VPN label processing mode as POPGO forwarding on an egress PE, which will pop the label for each packet and forward the packet out of the interface corresponding to the label.

Use undo vpn popgo to restore the default.

Syntax

Usage guidelines

After you execute the vpn popgo command, the egress PE disconnects and reestablishes BGP sessions to re-learn VPN routes.

After the vpn popgo command is executed, the egress PE does not support load sharing among VPN BGP peers.

To add two switches to an IRF fabric, configure the same VPN label processing mode (POPGO by using vpn popgo or POP by using undo vpn popgo) for the two switches. Otherwise, the two switches cannot form an IRF fabric. For more information about IRF, see IRF Configuration Guide.

vpn-target (VPN instance view/IPv4 VPN view/IPv6 VPN view)

Use vpn-target to configure route targets for a VPN instance.

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

Syntax

vpn-target vpn-target&<1-8> [ both | export-extcommunity | import-extcommunity ]

undo vpn-target { all | vpn-target&<1-8> [ both | export-extcommunity | import-extcommunity ] }

Default

No route targets are configured for a VPN instance.

Views

Predefined user roles

network-admin

mdc-admin

Parameters

vpn-target&<1-8>: Specifies route targets. &<1-8> means that you can specify up to eight route targets.

A route target is a string of 3 to 21 characters in one of these 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 route targets 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 route targets as export targets.

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

all: Removes all route targets.

Usage guidelines

MPLS L3VPN uses route targets to control the advertisement of VPN routing information. A PE adds the configured export targets into the route target attribute of routes advertised to a peer. The peer uses the local import targets to match the route targets of received routes. If a match is found, the peer adds the routes to the routing table of the VPN instance.

Route targets configured in VPN instance view are applicable to both the IPv4 VPN and the IPv6 VPN.

Route targets configured in IPv4 VPN view or IPv6 VPN view are applicable to only the IPv4 VPN or IPv6 VPN.

Route targets configured in IPv4 VPN view or IPv6 VPN view take precedence over those configured in VPN instance view. If you configure route targets in both IPv4 VPN view (or IPv6 VPN view) and VPN instance view, the IPv4 VPN or IPv6 VPN uses the route targets configured in IPv4 VPN view or IPv6 VPN view.

Examples

# Configure route targets for VPN instance vpn1.
