Description of problem: dnsmasq lacks the ra-param option Version-Release number of selected component (if applicable): Name : dnsmasq Arch : x86_64 Version : 2.66 Release : 14.el7_2.1 Additional info: The version of dnsmasq in RHEL7 lacks the ra-param option available in version 2.67 and above - which means that dnsmasq can't be used as a full replacement for radvd. The particular use case here is when routers switch over and you want to lower the route priority/lifetime of one vs. the other.
