XRd is a containerized model of IOS-XR the place you possibly can experiment with platform–impartial options and deploy them to any on-premises or cloud infrastructure. offering all the advantages of utilizing containers in community operations.
XRd comes with all of the programmability elements from IOS-XR, together with Telemetry and YANG fashions, which makes it superb for builders and community engineers.
The XRd sandbox offers a wonderful alternative to get began with XRd and discover community programmability.
XRd is available in two variants: XRd Management Plane and XRd vRouter. XRd Control Plane is superb for compute use instances like Digital Route Reflectors (vRR) or Path Compute Aspect (PCE). vRouter is designed to ahead visitors effectively and also can deal with management aircraft computations.
The XRd Sandbox makes use of the XRd Control Plane, which is superb for exploration and experimentation purposes.
XRd requires particular kernel settings on the host to work correctly. The sandbox is already configured with these settings.
There are a number of methods to deploy XRd, together with utilizing Terraform, Helm or Packer. Nevertheless, we used docker compose for the sandbox as a result of it’s easy and straightforward to handle.
Topology
For this sandbox, we primarily based on the pattern segment-routing topology from the xrd-tools GitHub repository. We used a customized compose format referred to as XR-YAML, and the complete setup can be deployed in a single digital machine (VM) utilizing Docker Compose.
Modifications
A few adjustments have been wanted to make the topology work. First, we updared the IP addressing for the administration community to match the obtainable sources in the sandbox.
Second, we used the macvlan Docker driver so every XRd container had its personal IP deal with as an alternative of sharing the IP deal with with the host VM.
See the XRd Sandbox GitHub repository for particulars and to discover the config recordsdata used to create the sandbox.
Deploy
The lab offers all the things you want; you’ll solely must create the compose file that can be utilized by Docker Compose. This file is created utilizing the xr-compose script from xrd-tools.
Subsequent, replace the compose file (created by xr-compose) to level to the best container interface that can be created by the macvlan driver.
The sandbox directions embrace the whole checklist of crucial instructions.
To begin experimenting, search for the XRd sandbox on the Cisco sandfield web page.
Launch a reservation and comply with the directions. Use the instructions to create and begin the topology.
The XRd sandbox is ideal to get aware of XRd, the right way to work with it, and to play with native community protocols (e.g., ISIS, OSPF, BGP, MPLS, SR) or to discover programmable use instances with YANG, NETCONF and GNMI.
When creating the sandbox, we ran right into a problem. We instantly misplaced the SSH connection to the VM when docker compose was creating the topology.
It turned out that the hyperlinks between XRd containers have been created utilizing docker bridge, which picked an IP phase utilized by the sandbox infrastructure, successfully blackholing the visitors. To repair it, we needed to configure a default deal with pool to make use of an unused IP phase.
After making use of this configuration, the problem was resolved.
