Configures the slow path forwarding of IPv4 and IPv6 multicast data packets.
Syntax
slow-path-forwarding { disable-all | enable-ssm | filter { acl-name | acl-number }
no slow-path-forwarding { disable-all | enable-ssm | filter { acl-name | acl-number }
Command Default

Slow path forwarding of IPv4 and IPv6 multicast data packets is enabled by default. Slow path forwarding of Source-Specific Multicast (SSM) groups is not enabled.

Parameters
disable-all
Disables the slow path forwarding of all IP multicast data packets.
enable-ssm
Enables slow path forwarding for SSM groups.
filter
Permits or denies the slow path forwarding of IP multicast data packets for groups in an access control list (ACL).
acl-name

Modes

PIM router configuration mode

PIM VRF router configuration mode

IPv6 PIM router configuration mode

IPv6 PIM VRF router configuration mode

Usage Guidelines

If assigning some SSM groups in an ACL to be associated with the filter keyword, slow path forwarding must first be enabled for the SSM group using the enable-ssm keyword

The no form of the command restores the defaults.

Examples

The following example disables the slow path forwarding for all IP multicast data packets. 

device# configure terminal
device(config)# router pim
device(config-pim-router)# slow-path-forwarding disable-all

The following example enables the slow path forwarding for SSM groups for IPv6 multicast data packets. 

device# configure terminal
device(config)# ipv6 router pim
device(config-ipv6-pim-router)# slow-path-forwarding enable-ssm
