domain-id
Use the domain-id command to configure an OSPF domain ID.
Use the undo domain-id command to restore the default.
Syntax
domain-id domain-id [ secondary ]
undo domain-id [ domain-id ]
Default
The OSPF domain ID is 0.
Views
OSPF view
Predefined user roles
network-admin
Parameters
domain-id: Specifies an OSPF domain ID 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: Specifies the domain ID as secondary. Without this keyword, the domain ID is primary.
Usage guidelines
When you redistribute OSPF routes into BGP on the MCE, 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 Type-3 LSAs; if yes but the routes are not intra-area
routes, OSPF advertises these routes in Type-5 or Type-7 LSAs. 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.
8
Examples
# Configure the OSPF domain ID as 234 for VPN instance vpn1.
<Sysname> system-view
[Sysname] ospf 100 vpn-instance vpn1

Parameters
vpn-instance-name: Specifies the name of a VPN instance, a string of 1 to 31 case-sensitive characters.
Usage guidelines
Perform this configuration on interfaces connected to a VPN site or a PE.
Associating a VPN instance with on an interface or removing the association clears the settings on the
interface. You have to reconfigure the settings for the interface. To view the settings on an interface, use
the display this command.
The associated VPN instance must have been created by using the ip vpn-instance command in system
view.
To modify the VPN instance associated with an interface, you must use the undo ip binding vpn-instance
command to remove the association, and then use the ip binding vpn-instance command to associate the
new VPN instance.

{ export | import }
Views
User view
Predefined user roles
network-admin
Parameters
vpn-instance-name: Specifies the name of a VPN instance, a string of 1 to 31 case-sensitive characters.
ip-address: Specifies the IP address of a peer.
all: Soft resets all BGP connections for the VPN.
external: Soft resets EBGP sessions for the VPN.
group group-name: Soft resets the connections with the specified BGP peer group. The group-name
argument is a string of 1 to 47 characters.
internal: Soft resets IBGP sessions for the VPN.
export: Performs a soft reset in the outbound direction to apply the new configuration to outbound BGP
updates.
import: Performs a soft reset in the inbound direction to request the peer to send BGP updates and apply
the new configuration to inbound BGP updates.
Usage guidelines
Soft reset enables BGP to refresh route information based on new configuration without breaking down
neighbor relationships. To perform soft reset, all BGP routers on the network must support route refresh.
If a router does not support route refresh, use the peer keep-all-routes command to save all routes
received from that router. The saved routes will be used during soft reset.
Examples
# Soft reset all BGP connections in VPN instance vpn1 in the inbound direction to apply new
configuration.
<Sysname> refresh bgp vpn-instance vpn1 all import
Related commands
peer keep-all-routes
reset bgp vpn-instance

Predefined user roles
network-admin
Parameters
route-distinguisher: Specifies the RD for the VPN instance, a string of 3 to 21 characters in one of the
following formats:
12
• 16 - bi t AS n u mb e r: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 overlapping address space. By prefixing an RD to an IPv4 prefix for a VPN, you
make the VPN IPv4 prefix globally unique.
NOTE:
To change the RD for a VPN instance, you must first delete the RD with the undo route-distinguisher
command, and then configure a new RD for the VPN instance with the route-distinguisher command.
Examples
# Configure an RD for VPN instance vpn1.
<Sysname> system-view
[Sysname] ip vpn-instance vpn1
[Sysname-vpn-instance-vpn1] route-distinguisher 22:1
routing-table limit
Use the routing-table limit command to set the maximum number of routes in a VPN instance.
Use the undo routing-table limit command to restore the default.

Predefined user roles
network-admin
Parameters
number: Specifies the maximum number of routes, in the range of 1 to 8192.
warn-threshold: Specifies a warning threshold, in the range of 1 to 100 in percentages. 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 permits new routes. If the number of routes in the
VPN instance reaches the maximum, no more routes are added.
simply-alert: Specifies that when the maximum route number is reached, the system still accepts routes
but generates a syslog.
Description
This command prevents the MCE from learning excessive routes.
13
The setting configured in IPv4 VPN view takes precedence over that configured in VPN instance view. If
you configure a limit in both IPv4 VPN view and VPN instance view, the IPv4 VPN uses the limit
configured in IPv4 VPN view.

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 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 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.
Description
Route targets are used to control VPN route learning. The MCE adds the specified export targets into
VPN routes advertised a peer. The peer compares the export targets in the received VPN routes against
the local import targets. If a match is found, the peer adds the received routes to the VPN routing table.
Route targets configured in IPv4 VPN view takes precedence over that configured in VPN instance view.
If you configure route targets in both IPv4 VPN view and VPN instance view, those configured in IPv4
VPN view are applied to the IPv4 VPN.
Examples
# Configure route targets for VPN instance vpn1.
<Sysname> system-view
[Sysname] ip vpn-instance vpn1
[Sysname-vpn-instance-vpn1] vpn-target 3:3 export-extcommunity
[Sysname-vpn-instance-vpn1] vpn-target 4:4 import-extcommunity
[Sysname-vpn-instance-vpn1] vpn-target 5:5 both
# Configure route targets for IPv4 VPN instance vpn2.
<Sysname> system-view
[Sysname] ip vpn-instance vpn2
[Sysname-vpn-instance-vpn2] ipv4-family
[Sysname-vpn-ipv4-vpn2] vpn-target 3:3 export-extcommunity
[Sysname-vpn-ipv4-vpn2] vpn-target 4:4 import-extcommunity
