BGP in 2023 – BGP Updates
the scalability of BGP as the Internet’s routing protocol is not just dependant on the number of prefixes carried in the routing table. BGP protocol behaviour in the form of dynamic routing updates are also part of this story. If the update rate of BGP is growing faster than we can deploy processing capability to match, then the routing system will lose coherence, and at that point the network will head into periods of instability. This report looks at the profile of BGP updates across 2023 to assess whether the stability of the routing system, as measured by the level of BGP update activity, is changing.New Processors Help Modernize the Data Center for AI
Enterprise and cloud data centers are using new compute and networking processors to run and speed up today’s more complex AI workloads.No More Roach Motels For Data In The Clouds
The central tenets of cloud computing, which really ought to be called utility computing, is that you only pay for what you use and that you can turn compute, storage, and networking off when you are not actually using, thus freeing up capacity for those who need it. …

Cloud Risk Management’s Time Has Come
The risks and stakes are growing as companies transfer more IT to the cloud. But are those companies really ready?HN716: Design-Driven Network Automation And Assurance
At AutoCon0 in November 2023, guest Jeremy Schulman delivered a talk from the main stage about delivering network assurance. If the term “network assurance” doesn’t mean anything to you, think about how you prove after an install or a change that the network is doing what it’s supposed to be doing. If you’re doing it...

VXLAN/EVPN – Host routing
In an previous post Advertising IPs In EVPN Route Type 2, I described use cases for advertising IP addresses in EVPN route type 2. Host ARP and host mobility I already covered so today we will focus on host routing.
To be able to show this scenario, I have added another server (SERVER-2) and will be using the topology below:
There is already existing configuration for VLAN 10 (L2 VNI) and for VLAN 100 (L3 VNI) which is shown below:
vrf context Tenant1
vni 10001
rd auto
address-family ipv4 unicast
route-target both auto
route-target both auto evpn
!
interface Vlan10
no shutdown
vrf member Tenant1
ip address 198.51.100.1/24
fabric forwarding mode anycast-gateway
!
interface Vlan100
no shutdown
mtu 9216
vrf member Tenant1
ip forward
To get SERVER-2 connected the following is needed:
- Configure VLAN 20 and map it to L2 VNI (VNI 10002).
- Make the L2 VNI a member of the NVE.
- SVI for VLAN 20.
- Configure port towards SERVER-2 in VLAN 20.
This is shown below:
vlan 20
vn-segment 10002
!
interface nve1
member vni 10002
ingress-replication protocol bgp
!
interface Vlan20
no shutdown
vrf member Tenant1
ip address 10.0.0.1/24
fabric forwarding mode anycast-gateway
!
interface Ethernet1/3

Painless Progress with My Ubiquiti Upgrade
I’m not a wireless engineer by trade. I don’t have a lab of access points that I’m using to test the latest and greatest solutions. I leave that to my friends. I fall more in the camp of having a working wireless network that meets my needs and keeps my family from yelling at me when the network is down.
Ubiquitous Usage
For the last five years my house has been running on Ubiquiti gear. You may recall I did a review back in 2018 after having it up and running for a few months. Since then I’ve had no issues. In fact, the only problem I had was not with the gear but with the machine I installed the controller software on. Turns out hard disk drives do eventually go bad and I needed to replace it and get everything up and running again. Which was my intention when it went down sometime in 2021. Of course, life being what it is I deprioritized the recovery of the system. I realized after more than a year that my wireless network hadn’t hiccuped once. Sure, I couldn’t make any changes to it but the joy of having a stable environment Continue reading

What do you get when you write code next to a Christmas tree? You can expect to get tons of eye candy, and that’s what netlab release 1.7.1 is all about.
It all started with a cleanup idea: I could replace the internal ASCII table-drawing code with the prettytable library. Stefan was quick to point out that I should be looking at the rich library, and the rest is history:
