Any idea if RA Guard will block unicast RAs? -- it wouldn't need to for the ordinary purpose of blocking misconfigured devices.

- zamadatix 6y agoI can't speak for every implementation in the world but at least most block both as it actually takes more work to create a filter that only blocks multicast RAs. The filter to block all is an automatic ACL saying "ICMP Type 136, direction ingress, action drop" and a multicast only version would take additional checks to do less.
