• As seen in above output that this vrID is not associated with any interface so it is not responsible for any VMAC configuration of netscaler. 

• Since type of this VRID is dynamic that means netscaler learned it from the local LAN. 

• So it seems like that there is a network device connected which is configured in a VRRP setup which is advertising its configured vrID in local LAN 

• Because of which we are seeing it on netscaler, but since a dynamically learnt VRID cannot be associated with any interface on ns so it barely has any signifance. 

If ADC has no VRRP configuration, the DYNAMIC learned VRRP won't function, hence no impact in this case.

There is no option to block VRRP announcement as of today.
ADC learns the vrid dynamically before the ACL takes effect. It does not have any functionality impact. 
 

But if you won't want to see the DYNAMIC learned VRID from show vrid, you should design Vlan properly.

Problem Cause

If you don't want ADC to join VRRP domain, it's improper to put ADC into same VLAN with VRRP group devices like following.
