Example
This example shows how to configure replacing the IPv4 packet priority to 4.

Switch(config)# mvlan
Switch(config)# mvlan 100
Switch(config-mvlan)# replace-priority ipv4 4
Switch(config-mvlan)#
69-7 replace-source-ip
This command is used to configure the source IP address which will be replaced into the reporting
IGMP/MLD packet to uplink ports. Use the no form of this command to cancel the source address
replacing.
replace-source-ip {ipv4 IPV4-ADDRESS | ipv6 IPV6-ADDRESS} from {source | receiver | both}
no replace-source-ip {ipv4 | ipv6}
Parameters
ipv4 IPV4-ADDRESS
ipv6 IPV6-ADDRESS
source
receiver
both
Default
None.
Command Mode
Multicast VLAN Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
The replace source IP option is used while reporting the join information towards the source port. The
purpose is to avoid the control packets dropped by the uplink router due to IP spoofing checks.
If the replacing address is configured, before forwarding the IGMP/MLD report/leave/done packet, sent by
the host, the source IP address in the report/leave/done packet will be replaced by this IP address.
Otherwise, the source IP address will not be replaced.
Example
This example shows how to configure the IPv4 and IPv6 replacing source address.
Switch# configure terminal
Specifies the source IP address for IGMP control packet reporting up
to routers.

routers.
Specifies that the source IP address of the IGMP report/leave packet
received on any multicast VLAN source port will be replaced.
Specifies that the source IP address of the IGMP report/leave packet
received on any multicast VLAN receiver port will be replaced.
Specifies that the source IP address of the IGMP report/leave packet
received on any port in the multicast VLAN will be replaced.
