Everything else is getting opened up — how about rack management?
I’ll continue to update this throughout the next two days. Feel free to issue a pull request if you’re also here at the conference and want to add to this post.
Location: Open Networking User Group (ONUG) at Columbia University
ONUG currently has 6 working groups:
It is interesting and awesome to see that half of the working groups are all about Day 2 operations and management of networks. This is exactly what’s needed in the industry.

I have been having issues using the F5 APM client behind a Juniper SRX-110 using hide NAT. I believe I’ve tracked it down to the default timeout settings used for UDP services. Here’s what I did to resolve it.
The laptop client was behind the SRX-110, using hide NAT. The initial client connection would work, and things would look good for a while. The the client would stop receiving packets. Traffic graphs would show a little bit of outbound traffic, and nothing inbound. Eventually, the client might decide it needed to reconnect. But usually, it would sit there for a few minutes doing nothing. Then I would force a disconnect, which would take a while, and then reconnect. Exceedingly frustrating.
Connecting the client to a different network – e.g. using a phone hotspot – worked fine. No dropouts. Using a wired connection behind the SRX had the same issue. So clearly the problem was related to the SRX.
I dug into the traffic flows to better understand what was going on. This SSL VPN solution makes an initial TLS connection using TCP 443. It then switches over to DTLS using UDP 4433 for ongoing encrypted Continue reading

BGP Dynamic Neighbors are a way to bring up BGP neighbors without specifically defining the neighbors remote IP address. Using the BGP Listen Range command you specify a range of IP addresses typically on your Hub site (maybe in a DMVPN environment) that you trust to become BGP neigbors with you. When a TCP request...

BGP PIC ( Prefix Independent Convergence ) is a BGP Fast reroute mechanism which can provides sub second convergence even for the 500K internet prefixes by taking help of IGP convergence. BGP PIC uses hierarchical data plane in contrast to flat FIB design which is used by Cisco CEF and many legacy platforms. In a hierarchical… Read More »
