Netns_identify utility is to check which network namespace a process is in. Starting OpenBSD Secure Shell server: sshdĬheck that the sshd_operns service is now listening on port 57722 in the global-vrf network namespace: Mon Mar 6 06:21: /etc/init.d/sshd_operns: Start sshd_operns Mon Mar 6 06:21: /etc/init.d/sshd_operns: OPERNS is ready Mon Mar 6 06:21: /etc/init.d/sshd_operns: Waiting for OPERNS management interface creation.

In 6.1.2, only global-vrf (default vrf) is supported in the linux environment for SSH and apps. Enabling it in a given network namespace (equivalent to XR vrf) opens up port 57722 on all the IP addresses reachable in that VRF. Users may choose to keep this disabled based on the kind of operations they intend to have. This is openssh running in the XR linux environment. RP/0/RP0/CPU0:ncs5508#show running-config ssh Choosing a key modulus greater than 512 may take a few minutes.

RP/0/RP0/CPU0:ncs5508# crypto key generate rsa Clone the following repository:, before we start.The topology here will require about 5G RAM and 2 cores on the user’s laptop. Meet the pre-requisites specified in the IOS-XR Vagrant Quick Start guide: Pre-requisites.If you’re bringing up the topology on your laptop using the IOS-XR vagrant box, then: They should be identical, except for reachability through the Management ports. In this case, a user may create and set up a container completely off-box, package it up as an image or a container tar ball, transfer it to the router and then load/import it, before running.įor each case, we will compare IOS-XR running as a Vagrant box with IOS-XR running on a physical box (NCS5500 and ASR9k). Tarball image/container: This is the simplest setup - very similar to LXC deployments. We won’t really tackle this scenario separately in this tutorial due to the absence of said certificate :). The steps used to set this up are identical to a private self-signed registry except for the creation of the certificate. Private “secure” registry: Set up reachability to your private registry, created using a certificate obtained from a CA. Private “self-signed” registry: This is more secure than the “insecure” setup, and allows a user to enable TLS. Private “insecure” registry: Some users may choose to do this, specially if they’re running a local docker registry inside a secured part of their network. All you need to do is set up reachability to dockerhub with the correct dns resolution. Public Dockerhub Registry: This is the simplest setup that most docker users would be well aware of. There are multiple ways to do this and we’ll explore each one: In this part, we explore how a user can spin up Docker containers on IOS-XR. Get users started with an IOS-XR setup on their laptop and incrementally enable them to try out the application-hosting infrastructure on IOS-XR.
