Hello, I'm currently working on my Master Thesis in Electrical and Computer Engineering at Instituto Superior Técnico, Lisbon, and was looking to use FRRouting to simulate routers using dockers. Is this possible and, if so, would you mind providing me with some information on this? Best regards, Sofia Salgueiro
Sofia, You can try from following link http://docs.frrouting.org/projects/dev-guide/en/latest/building-frr-for-alpi... On Wed, Mar 4, 2020 at 10:47 AM Sofia Salgueiro <sof97@live.com.pt> wrote:

Sofia, FRR is also available in CORE without needing to use docker. CORE uses Linux containers based on network namespaces. There is support for connection to external host or to external docker instances if needed. https://github.com/coreemu/core/releases (source, binaries) http://coreemu.github.io/core/ (documentation) <https://github.com/coreemu/core> https://discordapp.com/channels/382277735575322625/382277735575322627 (support channel) Cheers, Phil On Wed, 4 Mar 2020 at 14:47, Sofia Salgueiro <sof97@live.com.pt> wrote:

Sofia, Can you provide us (the community) with some idea of what you are trying to accomplish in your testing ? The reason I ask, is that there are several set of topology generation and emulation tools that you could use. If you are willing to use name spaces you can emulate quite large networks on a laptop, however if you want to do serious data forwarding you might need lots of real hardware / servers. What are you trying to accomplish ? /a

Hello, I just wanted to start by thanking you for the fast and helpful replies. To answer your questions, I'm looking to simulate a small network with about a dozen routers. I also want to test BGP configurations to simulate a small data center network. The network won't have much traffic but it would be useful to simulate delays between routers, if possible.

Hi Sofia, Regarding your last point, on Linux you can use tc-netem(8) to simulate several link characteristics such as delay, jitter, loss, etc. Here are a few useful links: * http://man7.org/linux/man-pages/man8/tc-netem.8.html * https://netbeez.net/blog/how-to-use-the-linux-traffic-control/ tc-netem can be used regardless of the software you're using to generate virtual network topologies (e.g. CORE, topotest, netgen). Usage example: # tc qdisc add dev eth0 root netem delay 100ms 10ms (delay of 100ms and random +-10ms uniform distribution). Regards, Renato.
