IP Multicast (IPMC) Commands
29-1 ip mroute
This command is used to create static routes for multicast. Use the no form of this command to delete the static routes.
ip mroute SOURCE-ADDRESS MASK {RPF-ADDRESS | null}
no ip mroute {SOURCE-ADDRESS MASK | all}
Parameters
SOURCE-ADDRESS Specifies the IP address of the static route.
MASK Specifies the network mask of the static route.
RPF-ADDRESS Specifies the RPF neighbor address.
null Specifies that if null is defined for the source network, the RPF check will always fail
for multicast traffic sent from this source network.
all Specifies that all the IP multicast static routes will be deleted.
Default
No any IP multicast static route exists.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 8. (EI Mode Only Command)
Usage Guideline
This command is used to create an IP multicast static route entry used by PIM to do
RPF check. When an IP multicast packet is received, the source IP address of the
packet will be used to do the RPF check. If the source IP address of the received IP
multicast packet matches the source network in a multicast static route, then it will be
allowed only when it comes from the RPF interface, and it will be RPF check failed if
it comes from other interfaces. If the source IP address of the received IP multicast
packet does not match any multicast static route source network, dynamic unicast
route will be used by PIM for RPF check.
To verify you configuration, use command show ip mroute static or show ip rpf.
Example
This example shows how to create a static route for network 139.1.1.1 255.255.0.0
for which the RPF neighbor address is 192.168.1.1.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#ip mroute 139.1.1.1 255.255.0.0 192.168.1.1
DXS-3600-32S(config)#
Example
This example shows how to configure the RPF checking if source network 10.1.1.1/
16 always fails.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#ip mroute 10.1.1.1 255.255.0.0 null
DXS-3600-32S(config)#
Example
This example shows how to delete a multicast static route for source network
10.1.1.1 255.255.0.0.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#no ip mroute 10.1.1.1 255.255.0.0
DXS-3600-32S(config)#
Example
This example shows how to delete all multicast static routes.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#no ip mroute all
DXS-3600-32S(config)#
