The details will vary depending on the overall multicast configuration but typically you set the desired group range as part of the RP configuration.

[edit routing-instances VPN-A protocols pim rp local]
user@host# set group-ranges ff70::/12
user@host# set group-ranges 224.0.0.0/4
The check list of all the multicast choices and required end to end configuration, including optional steps, can be found here.

Subject: multicast group - any way to change it?
Hello,
per my understanding multicast group cannot be changed on Juniper and I see this group on EX4300 239.255.255.255 , but Lightspeed agent network saying:
Multicast
- 224.0.0.1:3000 UDP – lsrelayd service
- 224.0.0.1:5000 UDP – lsfilterd service
I think they tested with Cisco switches which use the above multicast group. Is there any way to change it to 224.0.0.1 on Juniper?
Thank you
