What worries me more is the opportunity for adversaries to inject SRv6 packets. MPLS is not enabled by default on most 
router interfaces, so an adversary would have to have access to an interface where MPLS processing is explicitly 
enabled. IPv6 packet processing on the other hand… Unless an operator has airtight protection on every interface to 
block unwanted SRv6 headers I see some interesting opportunities to cause havoc :)
