Hi. I've enabled PIM on user's vlan, but user complain his firewall triggered with something like 13:26:25.811320 IP x.x.10.1 > 224.0.0.13: pim v2 Hello (Hold-time 1m45s) (Genid: 0x00000371) (DR-Priority: 1) (State Refresh Capable; v1) How can I disable this? I can't find something like "passive-interface" option for PIM.
