Just upgraded my RSVP-TE tunnels to 10 Pbps bandwidth in Cisco IOS XR. So much bandwidth for… traffic engineering activities! (It’s not a single interface, but your tunnels have never had more room.)

Cisco IOS XR Vulnerability: The BGP Bug That Crashed the Party!
A Cisco IOS XR flaw allows unauthenticated attackers to crash the BGP process on routers with a well-aimed BGP update. If you ever wanted to take down a carrier-grade router with the precision of a pro bowler, now’s your chance—just keep your AS_CONFED_SEQUENCE under 254 or face a DoS strikeout.
