ip pim register-source
ip pim register-source
To configure the IP source address of a register message to an interface address other than the outgoing
interface address of the designated router (DR) leading toward the rendezvous point (RP), use the ip pim
register-source command in global configuration mode. To disable this configuration, use the no form
of this command.
ip pim [vrf vrf-name] register-source interface-type interface-number
no ip pim [vrf vrf-name] register-source
Syntax Description
Command Default By default, the IP address of the outgoing interface of the DR leading toward the RP is used as the IP
source address of a register message.
Command Modes Global configuration
Command History
Usage Guidelines This command is required only when the IP source address of a register message is not a uniquely routed
address to which the RP can send packets. This situation may occur if the source address is filtered such
that packets sent to it are not forwarded or if the source address is not unique to the network. In these
cases, the replies sent from the RP to the source address fails to reach the DR, resulting in Protocol
Independent Multicast sparse mode (PIM-SM) protocol failures.
If no IP source address is configured or if the configured source address is not in service, the IP address
of the outgoing interface of the DR leading toward the RP is used as the IP source address of the register
message. Therefore, we recommend using a loopback interface with an IP address that is uniquely routed
throughout the PIM-SM domain.
vrf (Optional) Supports the multicast Virtual Private Network (VPN) routing
and forwarding (VRF) instance.
vrf-name (Optional) Name assigned to the VRF.
interface-type
interface-number
Interface type and interface number that identify the IP source address of a
register message.
