protocols pim6 dense-group <ip-address>

Uses the dense-group keyword to force the interface PIM mode for a group to be dense - even if an RP(G) is present.

set protocols pim6 dense-group ip-address
delete protocols pim6 dense-group ip-address
show protocols pim6 dense-group ip-address
ip-address
The IPv6 address for the data plane. The format of the IPv6 address is h:h:h:h:h:h:h:h/x.

Configuration mode.

protocols {
        
        pim6 {
                dense-group ff1e::225:0:0:33
                rp-address beef::5:5:5:5 {
                        list 1
                }
        }
}

PIM dense-groups are added to force designated groups to be dense when otherwise an RP(G) would be present (useful given that access lists in the context of PIM do not support "deny" entries - just "permit").

Of particular significance is that SDM requires at least one RP to be present in the network in order to function - even in the absence of an RP(G) for any multicast group. Without an RP, DM traffic will not flow via SDM configured interfaces (unless connected interfaces on adjoining routers are configured for DM).

Use the set version of the command to force the interface PIM mode for a group to be dense.

Use the delete version of the command to undo the PIM configuration.

Use the show version of the command to display the PIM configuration.

The following example shows the use of dense-group and access-list in the context of SDM.

policy {
        route {
                
                access-list6 1 {
                        rule 1 {
                                action permit
                                source {
                                        network ff1e::225:0:0:0/120
                                }
                        }
                }
        }
}
protocols {
        
        pim6 {
                dense-group ff1e::225:0:0:33
                rp-address beef::5:5:5:5 {
                        list 1
                }
        }
}
Note: The group must be defined as source rather than destination.
