2: System level

Parameters

group-address: Multicast group address, in the range of 224.0.1.0 to 239.255.255.255.

mtunnel-number: Number of the MTI interface to be created. The value range varies with the system working modes. For more information, see Fundamentals Configuration Guide.

Description

Use the multicast-domain share-group command to configure a share-group address and associate an MTI with the current VPN instance.

Use the undo multicast-domain share-group command to restore the default.

By default, no share-group address is configured and no MTI is associated with a VPN instance.

To specify a multicast group address in the public network SSM group range as a share-group address, you must first configure BGP MDT peers or peer groups.

On the same PE device, different VPN instances must not have the same group address, and group-address must not coincide with the switch-group address of any VPN instance; in addition, mtunnel-number must not coincide with the number of any MTI already created.

This command must not be used repeatedly in the same VPN instance view. To configure a new group address and MTI for a VPN instance, you must remove the existing configuration.

The undo multicast-domain share-group command removes the configured MTI and the configurations of the multicast-domain switch-group-pool, multicast-domain log switch-group-reuse and multicast-domain switch-delay commands.

IP multicast routing must be enabled in the VPN instance before this command can take effect.

Related commands: multicast routing-enable, multicast-domain log switch-group-reuse, multicast-domain switch-delay, and multicast-domain switch-group-pool.

# Specify 224.1.1.1 as the share-group address in VPN instance mvpn and associate MTI 0 with the VPN instance.

multicast-domain switch-delay

Default level

2: System level

Parameters

switch-delay: Switch-delay period in seconds, namely, the delay time for multicast traffic to be switched from the share-MDT to the switch-MDT, in the range of 3 to 60.

Description

Use the multicast-domain switch-delay command to configure the switch-delay period.

Use the undo multicast-domain switch-delay command to restore the default.

By default, the switch-delay period is 5 seconds.

Examples

# Set the switch-delay period to 20 seconds in VPN instance mvpn.

multicast-domain switch-group-pool

Syntax

multicast-domain switch-group-pool switch-group-pool { mask | mask-length } [ acl acl-number ]

undo multicast-domain switch-group-pool

View

VPN instance view

Default level

2: System level

Parameters

switch-group-pool: The start address of the switch-group-pool, in the range of 224.0.1.0 to 239.255.255.255.

mask: Mask for addresses in the switch-group-pool, the range of which varies with the system working modes. For more information, see Fundamentals Configuration Guide.

mask-length: Mask length for addresses in the switch-group-pool, the range of which varies with the system’s working mode. For more information, see Fundamentals Configuration Guide.

acl-number: Advanced ACL number, in the range of 3000 to 3999. An advanced ACL defines the (S, G) entry or entries to which the configured MDT switching condition will apply. If you do not specify an ACL, the configured MDT switching condition will apply to all (S, G) entries. When you configure this ACL, specify the protocol type as IP and use the source and destination parameters to specify a multicast source address range and a multicast group address range respectively.

Description

Use the multicast-domain switch-group-pool command to configure the address range of the switch-group-pool and the switching condition.

Use the undo multicast-domain switch-group-pool command to restore the default.

By default, no switch-group-pool is configured and multicast traffic is never switched to a switch-MDT.

This command cannot be configured without the previous share-MDT configuration in the VPN instance.

On a given PE device, the switch-group address range for a VPN must not contain the share-group of any VPN.

On a given PE device, the switch-group address range for a VPN instance must not overlap with that for any other VPN instance. A new configuration with this command in the same VPN instance supersedes the existing configuration.

If you use the multicast-domain switch-group-pool command on a switch, share-MDT to switch-MDT switching will take place after the switch receives multicast traffic for this VPN instance and has maintained it for the switch-delay period.

Related commands: multicast-domain switch-delay.

Default level

2: System level

Parameters

group-name: Name of a BGP MDT peer group, a case-sensitive string of 1 to 47 characters. A peer name must not contain any space.

ip-address: IP address of a BGP MDT peer.

Description

Use the peer reflect-client command to configure the router as a route reflector and specify a peer or peer group as its client.

Use the undo peer reflect-client command to remove the configuration.

By default, neither route reflectors nor clients are configured.

Before you configure this command, BGP MDT peers or peer groups should be configured.

Your configuration will overwrite the old configuration (if any).

Related commands: peer enable, reflect between-clients, and reflect cluster-id.

Default level

2: System level

Parameters

None

Description

Use the reflect between-clients command to enable route reflection between clients.

Use the undo reflect between-clients command to disable this function.

By default, route reflection between clients is enabled.

Related commands: peer reflect-client and reflector cluster-id.

reflector cluster-id (BGP-MDT sub-address family view)

Syntax

reflector cluster-id { cluster-id | ip-address }

undo reflector cluster-id

View

Default level

2: System level

Parameters

cluster-id: Cluster ID of the route reflector, in the range 1 to 4294967295.

ip-address: Cluster ID of the route reflector, which is the IP address of the specified BGP MDT peer.

Description

Use the reflector cluster-id command to configure the cluster ID of the route reflector.

Use the undo reflector cluster-id command to remove the configured cluster ID.

By default, a route reflector uses its router ID as the cluster ID.

In general, a cluster has only one route reflector whose router ID identifies the cluster. However, you can configure several route reflectors in a cluster to improve network reliability, and they must have the same cluster ID configured to avoid routing loops.

Related commands: reflect between-clients and peer reflect-client.

Examples

# Specify 80 as the cluster ID for the route reflector.
