Chaning the PIM-DR in a MPLS-MDT Cloud

Hi @ all

we want to change the PIM-DR in a MPLS MDT enviroment.

Aktual alwas the PE with the hightes IP Address would be choosen for the DR.

We want to add some new PE´s outside our Campus, so we want do define the PE who is the DR.

HSV-2b#sh ip pim vrf VPN-XXXX neighbor

PIM Neighbor Table

Mode: B - Bidir Capable, DR - Designated Router, N - Default DR Priority,

      P - Proxy Capable, S - State Refresh Capable, G - GenID Capable

Neighbor          Interface                Uptime/Expires    Ver   DR

Address                                                            Prio/Mode     Vlan300                  00:00:05/00:01:39 v2    1 / S P G      Tunnel4                  1d02h/00:01:37    v2    1 / S P G      Tunnel4                  1d02h/00:01:18    v2    1 / S P G    Tunnel4                  1d02h/00:01:39    v2    1 / S P G    Tunnel4                  1d02h/00:01:20    v2    1 / DR S P G      Tunnel4                  1d02h/00:01:42    v2    1 / S P G

we are unable to configure the interface tunnel 4 with the "pim pim DR-Priority" command

HSV-2b(config)#interface tunnel 4

%Tunnel4 used by IP Multicast VPN MDT, configuration not allowed

Also configureing the Loopback interface didn´t change the DR

How can we define (without changing the IP address from the PE) the PIM-DR
