group wildcard source wildcard

Function

The group wildcard source wildcard command sets a tunnel type for the switching of the traffic matching wildcard (*, *) between Inclusive-Provider Multicast Service Interface (I-PMSI) and Selective-Provider Multicast Service Interface (S-PMSI) tunnels.

The undo group wildcard source wildcard command restores the default configuration.

By default, no address pool range or criteria are configured for switching between I-PMSI and S-PMSI tunnels.

Format

group wildcard source wildcard { mldp | rsvp-te p2mp-template p2mp-te-template-name | bier [ sub-domain sub-domain-val ] [ bsl { 64 | 128 | 256 } ] }

Parameters

Parameter	Description	Value
mldp	Specifies the S-PMSI tunnel type as mLDP.	-
rsvp-te	Specifies the S-PMSI tunnel type as RSVP-TE.	-
p2mp-template p2mp-te-template-name	Specifies the name of a tunnel template to be referenced by an RSVP-TE P2MP tunnel.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported.
bier	Indicates a BIER tunnel.	-
sub-domain sub-domain-val	Specifies the ID of a BIER subdomain.	The value is an integer ranging from 0 to 255.
bsl	Specifies a BSL.	The values are as follows: 64,128 and 256 The default value is 256.
wildcard	Specifies any address.	-
source	Specifies a source address for switching between I-PMSI and S-PMSI tunnels.	The value is in dotted decimal notation.

Usage Guidelines

Usage Scenario

An NG MVPN uses the I-PMSI tunnel to send multicast data to receivers. The I-PMSI tunnel connects to all PEs on the MVPN and sends multicast data to these PEs regardless of whether these PEs have receivers. If some PEs do not have receivers, this implementation will cause redundant traffic, wasting bandwidth resources and increasing PEs' burdens.

S-PMSI tunnels solve this problem by sending multicast data only to PEs interested in the data.

To configure the address pool range and criteria for switching between I-PMSI and S-PMSI tunnels, run the group command.

The restrictions on the wildcard parameter are as follows:

Wildcard (*, *):

Wildcard (*, *) and I-PMSI cannot be configured together.
Wildcard (*, ) and wildcard (, G) cannot be configured together.

Precautions

Up to 1024 such commands can be configured for each VPN, and up to 16384 such commands can be configured on an entire device, and the maximum limit value in a group command configuration is 8192.
Up to 8192 S-PMSI tunnels can be configured for each VPN instance.
If the address pool range specified in a group command overlaps with a previously configured address pool range, the command cannot be configured.
If you want to change the tunnel type configured for an address pool range, you must delete the existing group command configuration and then run the group command with the desired tunnel type.

Example

# Set the tunnel type to mLDP P2MP for the switching of the traffic matching wildcard (*, *) between I-PMSI and S-PMSI tunnels.
