 · More than five years after the MPLS/VPN-in-mGRE encapsulation was standardized (add a few more years for the work-in-progress and IETF draft stages), it finally debuted in a mainstream-wannabe IOS release running on ISR routers (15.1(2)T), making it usable for the enterprise WAN designers, who are probably its best target audience.
