rpf-frr clone interface-inheritance

Function

The rpf-frr clone interface-inheritance command enables cloned (S, G) entries to inherit the outbound interfaces of (*, G) entries.

The undo rpf-frr clone interface-inheritance command disables cloned (S, G) entries from inheriting the outbound interfaces of (*, G) entries.

By default, cloned (S, G) entries are not enabled to inherit the outbound interfaces of (*, G) entries.

Format

rpf-frr clone interface-inheritance [ policy { acl-number | acl-name acl-name } ]

undo rpf-frr clone interface-inheritance [ policy { acl-number | acl-name acl-name } ]

Parameters

Parameter	Description	Value
policy	Applies a policy to define the range of cloned (S, G) entries that can inherit the outbound interfaces of (*, G) entries.	-
acl-number	Specifies an ACL number.	The value is an integer ranging from 2000 to 3999.
acl-name acl-name	Specifies an ACL name.	The value is a string of 1 to 64 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive).

Parameter

Description

Value

policy

Applies a policy to define the range of cloned (S, G) entries that can inherit the outbound interfaces of (*, G) entries.

Specifies an ACL number.

The value is an integer ranging from 2000 to 3999.

acl-name acl-name

Specifies an ACL name.

The value is a string of 1 to 64 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive).

Usage Guidelines

Usage Scenario

If multicast user terminals run IGMPv2, cloned (S, G) entries need to inherit the outbound interfaces of (, G) entries, allowing such user terminals to receive two copies of the same multicast flow. However, to prevent duplicated data, cloned (S, G) entries are disabled from inheriting the outbound interfaces of (, G) entries by default. Therefore, if multicast user terminals running IGMPv2 exist on interfaces, run the rpf-frr clone interface-inheritance command to enable (S, G) entries to inherit the outbound interfaces of (*, G) entries.

Prerequisites

PIM FRR has been enabled using the rpf-frr command.

Precautions

Only the NetEngine 8000 F1A supports this command.
