hi out there
I have a log-notice on our nexus 7000:
2014 Mar 14 04:16:37 ve-coresw-01 %PIM-5-DR_CHANGE: pim [26128] DR change from 172.21.159.253 to 172.21.144.3 on interface V

We are using microsoft terminalservers with MS NLB (WLBS) in multicast mode. They are hosted in a rack of VMWare servers - we have the nexus 7k running with a failover unit which is running HSRP in between and on the SVI VLAN 2001 we are running pim sparse mode.
It seems to run fine but I get these notes in the log-file which tells me that the designated router changes from the one nexus to the other from time to time. Can somebody tell me the consequence of what is happening with the current sessions running while this is going on?
And is there a simple way to awoid this DR change from the one site to the other (define prioroty and/or timers?)
best regards /ti
