pimd: API for enabling pim on the vxlan term device ipmr-lo
ipmr-lo is a dummy netdev with no additional addressing requirements -
root@TORS1:~# ip -d link show ipmr-lo
28: ipmr-lo: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default
link/ether 12:5a:ae:74:51:a2 brd ff:ff:ff:ff:ff:ff promiscuity 0
dummy addrgenmode eui64
