Configuring a Static Multicast Route (mroute) (CLI)
You can use the following procedure to configure static mroutes. Static mroutes are similar to unicast static
routes but differ in the following ways:
•
Static mroutes are used to calculate RPF information, not to forward traffic.
•
Static mroutes cannot be redistributed.
Static mroutes are strictly local to the device on which they are defined. Because Protocol Independent Multicast
(PIM) does not have its own routing protocol, there is no mechanism to distribute static mroutes throughout
the network. Consequently, the administration of static mroutes tends to be more complicated than the
administration of unicast static routes.
When static mroutes are configured, they are stored on the device in a separate table referred to as the static
mroute table. When configured, the ip mroute command enters a static mroute into the static mroute table
for the source address or source address range specified for the source-address and mask arguments. Sources
that match the source address or that fall in the source address range specified for the source-address argument
will RPF to either the interface associated with the IP address specified for the rpf-address argument or the
local interface on the device specified for the interface-type and interface-number arguments. If an IP address
is specified for the rpf-address argument, a recursive lookup is done from the unicast routing table on this
address to find the directly connected neighbor.
If there are multiple static mroutes configured, the device performs a longest-match lookup of the mroute
table. When the mroute with the longest match (of the source-address) is found, the search terminates and the
