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.) Check out: cs.co/6011AheB9 #CiscoDevNet #IOSXR #pushdastuff
You *may* have noticed small disturbance of the force with regards to BGP Full Feed and BGP Blackholing projects. That's because over last two nights I migrated all infra to... this ;) #iosxr #xrv9000 #pushdastuff
GYAN of the DAY, IOS-XR blocks E-BGP updates without a route policy. Know this to configure your routers like a pro! 🚀🧠 #BGP #EBGP #IOSXR #Cisco #Routing #RoutePolicy #CCNA #CCNP #CCIE #NetworkingFacts #NetworkEngineer #RouterConfiguration #CiscoIOS #TechTips #DidYouKnow
I mean... it's unfair, but next to this shiny 9001 my Radeon 7800XTX is basically silent. Maybe I should repaste it as well? ;) /cc @GamersNexus #iosxr #asr9001 #pushdastuff
Hey @xrdocs, @fcuiller look what I just found in my lab rack. Would that work as home edge router? Does it support WPA3? Or UPnP? ;) #iosxr #cisconcs #ipv6 #100ge #400ge

If You want to experiment with BGP FlowSpec on your router, there's alpha version of my BGP Blackholing FlowSpec server at 85.232.240.180 & 2001:1a68:2c:2::180. The rest of configuration is the same as in main project: lukasz.bromirski.net/bgp-blackholin… #iosxr #pushdastuff #bgp #blackholing

Qq a déjà eu un soucis sous #cisco #iosxr avec un user RO ( je précise bien RO via group/taskgroup) mais qui ne montre pas toute la config malgré tout ? Idem via user local ou tacacs. J’ai envie de dire bug… mais prêté un soucis de layer8

Went quickly back in @CiscoFrance lab in Paris today to setup big routers #asr9k running #iosxr . What a nice feeling to walk in the office and work in lab room.
