This week we talk about:
My sources inform me that most of the MUM EU 2019 announced products will be released till MUM EU 2020, in worst case (china virus) MUM US 2020
All CRS3XX switches have same switching ASICs. They simply added the MIPSBE CPU since it was their most common to run ROS.
MUM US coming up; TBW will have a panel again.
Zach was asking how to determine how long a BGP route has been cached in a Cisco router – “show bgp x.x.x.x” in IOSXR.
BGP lab back up. CCR to ASR9K pulls 780K routes in about 20 seconds.
RFC2544 testing with an AGILENT DELL FRAMESCOPE PRO
Nick B does packet pushers – segment routing
To fuse each DC device or not – the BlueSea fuse block makes it cheap and easy to do so. Thanks for the tip Ryan McAfee.
Simon Green – how to make a mikrotik bridge invisible. Turn off STP and Neighbor discovery…how invisible do you want it?
Powering PoE and direct power MTK kit – use different voltages for each.
Unimus 2.0.0-Beta1 next week
SpaceX Starlink updates (ground station forwarding still faster than land-based fiber)
