Examples
# Set the switch-delay period to 20 seconds in VPN instance mvpn.
<Sysname> system-view
[Sysname] ip vpn-instance mvpn
[Sysname-vpn-instance-mvpn] multicast-domain switch-delay 20
multicast-domain switch-group-pool
Use multicast-domain switch-group-pool to configure the address range of the switch-group-pool and the
switching condition.
Use undo multicast-domain switch-group-pool to restore the default.
Syntax
multicast-domain switch-group-pool switch-group-pool { mask | mask-length } [ threshold
threshold-value | acl acl-number ] *
undo multicast-domain switch-group-pool
Default
No switch-group-pool is configured and multicast traffic is never switched to a switch-MDT.

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.
mask-length: Mask length for addresses in the switch-group-pool, in the range of 24 to 32.
threshold-value: Traffic rate threshold that will trigger MDT switching in kbps. The value range is 0 to
4194304, and the default is 0 kbps.
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 applies. If you do not specify an ACL,
the configured MDT switching condition applies to all (S, G) entries. When configuring 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.
Usage guidelines
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.
