There is no no version.
See ip route-type.
An mroute is a multicast traffic flow (a (Source, Group) entry used for forwarding multicast
traffic). By default, forwarding mroutes (with a valid RPF incoming interface) are timed
out if data for them is not received for 210 seconds. However, you can specify an mroute
as permanent by using the ip multicast-routing permanent-mroute command.
Use to specify that any newly created mroutes that match the specified access-list
do not time out.
Using this command does not change existing mroutes.
Permanent mroutes are removed if a topology change occurs that affects the mroute.
Permanent mroutes may be removed due to certain protocol actions (for example,
PIM sparse-mode switching from shared to shortest-path tree).
Outgoing interface lists of permanent mroutes may change due to protocol actions.
Example
host1(config)#ip multicast-routing permanent-mroute routes1
Use the no version to prevent any new mroutes from becoming permanent. To remove
existing permanent mroutes, use the clear ip mroute command.
See ip multicast-routing permanent-mroute.
Multicast interface-level admission control, port-level admission control, and QoS
adjustment all use a single multicast bandwidth map. The multicast bandwidth map is
a route map that uses the set admission-bandwidth, set qos-bandwidth, set
admission-bandwidth adaptive, or set qos-bandwidth adaptive commands. The
adaptive commands configure an autosense mechanism for measuring the multicast
bandwidth.
NOTE: Even though you can include any of the preceding commands several
times in a route map entry, only the last admission-bandwidth command or
qos-bandwidth command in the bandwidth map is used. In other words, if
you included the set qos-bandwidth command first and then the set
qos-bandwidth adaptive command, the bandwidth map uses the set
qos-bandwidth adaptive command.
Interface-level and port-level admission control is performed when an OIF on the interface
or port is added to the mroute for a given (S,G) multicast data stream and the multicast
