Configuring RSVP-TE P2MP

RSVP-TE P2MP adds support for Point-to-Multipoint (P2MP) LSPs. RSVP P2MP functionality is enabled by entering the P2MP submode.
switch# config 
                switch(config)# mpls rsvp 
                switch(config-mpls-rsvp)# no shutdown 
                switch(config-mpls-rsvp)# p2mp 
switch(config-mpls-rsvp-p2mp)#
P2MP functionality can be disabled by issuing the disabled command in the P2MP submode. 
switch(config-mpls-rsvp-p2mp)# disabled
Alternatively, the submode can be removed altogether to disable P2MP functionality. Note that this will also remove any existing configuration under the p2mp submode. 

switch(config-mpls-rsvp-p2mp)# exit 
switch(config-mpls-rsvp)# no p2mp
