MULTICAST COMMANDS
IP
MROUTE
ip mroute
Overview Use this command to inform multicast of the RPF (Reverse Path Forwarding) route
to a given IPv4 multicast source.
Use the no variant of this command to delete a route to an IPv4 multicast source.
Syntax
ip mroute <ipv4-source-address/mask-length>
[bgp|ospf|rip|static] <rpf-address> [<admin-distance>]
no ip mroute <ipv4-source-address/mask-length>
[bgp|ospf|rip|static]
Syntax (VRF lite) ip mroute [vrf <vrf-name>] <ipv4-source-address/mask-length>
[bgp|ospf|rip|static] <rpf-address> [<admin-distance>]
no ip mroute [vrf <vrf-name>] <ipv4-source-address/mask-length>
[bgp|ospf|rip|static]
Mode Global Configuration
Usage Typically, when a Layer 3 multicast routing protocol is determining the RPF
(Reverse Path Forwarding) interface for the path to an IPv4 multicast source, it uses
the unicast route table to find the best path to the source. However, in some
Parameter Description
vrf Applies the command to the specified VRF instance.
<vrf-name> The name of the VRF instance.
<ipv4-source-
address/mask-length>
A multicast source IPv4 address and mask length, in
dotted decimal notation in the format A.B.C.D/M.
bgp BGP unicast routing protocol.
ospf OSPF unicast routing protocol.
rip RIP unicast routing protocol.
static Specifies a static route.
<rpf-address> A.B.C.D
The closest known address on the multicast route back
to the specified source. This host IPv4 address can be
within a directly connected subnet or within a remote
subnet. In the case that the address is in a remote
subnet, a lookup is done from the unicast route table to
find the next hop address on the path to this host.
<admin-distance> The administrative distance. Use this to determine
whether the RPF lookup selects the unicast or multicast
route. Lower distances have preference. If the multicast
static route has the same distance as the other RPF
sources, the multicast static route takes precedence.
The default is 0 and the range available is 0-255.
