Does MICE have an blackholng functionality equivalent to SIX?
I was visiting with a DDoS mitigation vendor this morning and was curious if there was a way we could automatically mitigate DoS attack traffic coming from a MICE peer.
You can adjust the routing with communities, ie. in the MICE communities aera of
http://micemn.net/technical.htmlyou could block-hole the AS that is sending you that traffic.
unfortunately, that just has the effect of traffic going elsewhere - not a blackhole effect. the communities in place would just cause the route not to be advertised to said peer, and the traffic would just ingress your network via a different path. In the case of a DDOS, it’s likely you have multiple ASN’s targeting you.
SIX, as an example, has a blackhole IP address, and the route servers matching a blackhole community to set next hop to this to sink the traffic on the switch fabric.
Perhaps something we should look into for MICE.
