The multicast group ip address for BUM traffic is configurable per-l2-vni. One way to configure that is to setup a vxlan device that per-l2-vni and specify the address against that vxlan device - root@TORS1:~# vtysh -c "show interface vx-1000" |grep -i vxlan Interface Type Vxlan VxLAN Id 1000 VTEP IP: 27.0.0.15 Access VLAN Id 1000 Mcast 239.1.1.100 root@TORS1:~# vtysh -c "show evpn vni 1000" |grep Mcast Mcast group: 239.1.1.100 root@TORS1:~# Signed-off-by: Anuradha Karuppiah <anuradhak@cumulusnetworks.com>
