| − | = Nokia/Cumulus Multi-Vendor Lab =
| + | Welcome to our Labs Wiki page. |
| | | | |
| − | The targets of this lab are to :
| + | Here you'll find our shares about what we've experimented in lab. Results / observations could change today with latest versions and our knowledge improvement. |
| | | | |
| − | * mix Nokia SR-Linux and Cumulus VXLAN nodes, in spine or leaf roles
| + | Don't hesitate to share your feedbacks, thanks. |
| − | * make this environment work for different kinds of setup : cross-DC L2, differentiated L3 gateways per leaf per VRF, anycast gateway cross or intra DC, etc.
| |
| − | * spot compatibility issues if existing
| |
| | | | |
| − | To reach those goals, we'll use the Nokia lab tool "containerlab" https://containerlab.srlinux.dev/, labs from https://clabs.netdevops.me/ helped a lot. Many thanks to the contributors.
| + | = VyOS/Arista/CVX Lab with EVE-NG = |
| | | | |
| − | We'll need a Linux host with Docker installed on it + kvm virtualization enhancements activated (important if your host is a VM). If virtualization optimization is not ok, you won't be able to launch the most of devices.
| + | [[VyosAristaCVX-VXLAN-lab]] |
| | | | |
| − | Installation details are referenced there : https://containerlab.srlinux.dev/install/
| + | = Nokia/Cumulus ContainerLab = |
| | | | |
| − | Once installed, you'll need to register the different NOS images you'll use. Cumulus image is present on a public registrery, but Nokia/Arista/Juniper are not, you'll need a vendor support account to retreive them. Once downloaded (.tgz file typically) you can "docker load" the image :

| + | = SONiC with Docker = |
| − | sudo docker load -i 21.6.1-235.tar.xz /* (Nokia) */
| |
| − | sudo docker load -i cEOS64-lab-4.26.1F.tar /* (Arista) */
| |
| − | </syntaxhighlight>For public images :<syntaxhighlight lang="bash">
| |
| − | sudo docker pull networkop/cx:4.3.0 /* (Cumulus) */
| |
| − | </syntaxhighlight>
| |
| | | | |
| − | To verify your installed images, you can run "sudo docker images"<syntaxhighlight lang="bash">

| − | </syntaxhighlight>Once you've got all your images, to run the lab, you'll need a .yml file defining the topology to run.
| + | = M-Vendor VXLAN Lab with EVE-NG = |
| | | | |
| − | In our lab, we've started with the 5-clos lab file from Nokia site, which we've forked.
| + | [[Mvendor-VXLAN-lab]] |
| − | | |
| − | We can see there is a branch "kinds" where we can define templates of nodes, in order to not rewrite whole parameters when creating nodes. For the images, it's important to take the repository name + tag.
| |
| − | | |
| − | '''Note:''' If the tag is "latest" it is not needed.

| − | </syntaxhighlight>The containerlab program creates the updates into the host file + generates an ansible inventory file.
| |
| − | | |
| − | There are different ways to connect onto the docker instances, within docker exec commands or SSH directly the IP address related above.
| |
| − | | |
| − | For example :<syntaxhighlight lang="bash">
| |
| − | sudo docker exec -it clab-lab-srl-cum-spine1 bash
| |
| − | </syntaxhighlight>-->>> allows to launch a bash on the cumulus device (then you run the different net commands)<syntaxhighlight lang="bash">

| − | </syntaxhighlight>-->>> allows to launch the cli on a SRLinux device
| |
| − | | |
| − | | |
| − | To end this setup preparation, the containerlab tool integrates an option to launch a webserver showing the lab topology in graph + node details
| |
| − | | |
| − | By default, it's listening on port 50080 of the host
| |
| − | | |
| − | Then, you can access to the following web page showing the topology + lab infos

| − | | |
| − | Firstable, once you ve finished your "hand made config", you can run the following command to save it :<syntaxhighlight lang="bash">
| |
| − | containerlab save -t quickstart.clab.yml
| |
| − | </syntaxhighlight>'''To be noted it's only working for Nokia nodes in this lab'''. CVX configurations will have to be called by another method (or pushed manually)
| |
| − | | |
| − | It will create one folder per node into the lab folder which gives the following tree :
| |
| − | [[File:Topology-srl.jpg|ohne|mini]]
| |
| − | | |
| − | | |
| − | '''Note''': For Cumulus, you can apparently retrieve configurations files within adding the following parameters into lab config file. '''To be tested.''' some lab samples here : https://github.com/hellt/clabs/blob/main/labs/cvx04/symm-mh.clab.yml

| − | * eBGP will be used for Underlay and Overlay
| |
| − | * eBGP single-hop sessions are established over direct point-to-point links interconnecting the network nodes, no multi-hop or loopback sessions are used, even in the case of multiple links between the same pair of nodes.
| |
| − | * Private Use ASNs from the range 64512-65534 are used to avoid ASN conflicts.
| |
| − | * A single ASN is allocated to all of the Clos topology's Tier 1 devices.
| |
| − | * A unique ASN is allocated to each set of Tier 2 devices in the same cluster.
| |
| − | * A unique ASN is allocated to every Tier 3 device (e.g., ToR) in this topology.
| |
| − | | |
| − | In add, depending of network nodes, it will be interesting to :
| |
| − | | |
| − | * Add fast-failover option for underlay + add link-debounce on links to limit possible impacts in case of link flaps. BFD could be considered in some cases
| |
| − | * Have the best ECMP hashing algorythm on leaf nodes. On tier-1/tier-2 levels hashing will be based on underlay part (trafic inter-vtep), so L3-L4 decision, but some models can retreive the vni-id if I well remember.
| |
| − | * Implement the "multipath relax" since we could have multiple AS paths for a same destination.
| |
| − | * Implement gshut community on underlay (on tier-1/tier-2) or at least policies to prepend underlay routes to avoid some nodes in case of maintenance.
| |
| − | | |
| − | == Thoughts/Points to deepend ==
| |
| − | On leaf nodes, LACP over multiple nodes is feasible within ESI, but impact on incidents/maintenance can vary depending on the vendors.
| |
| − | | |
| − | '''Tests need to be done to check that.'''
| |
| − | | |
| − | Some sysadmin would like to KISS and have client servers connected in active/passive bonding, with eventually single-leaf ports aggregation.
| |
| − | | |
| − | '''Note :''' NH ESI in FIB management on ingress nodes can have some limitations (numbers of installable next-hop, load-balancing, etc. oftenly linked to the node chipset)
| |
| − | | |
| − | | |
| − | Another important engineering point to define at the beginning is : '''Do we authorize multisite L2 propagation or not ?'''
| |
| − | | |
| − | From my point-of-view, the smaller are the L2 segments the better it is. I would suggest Local L2 segments wit anycast gateways provided by Leaf switches, with L3 routing between DCs within EVPN type5 routes sharing only. Nevertheless, some business requirements for endcustomers can keep extended L2 alive.
| |
| − | | |
| − | We have to be careful when implementing Consistent hashing. ex: <nowiki>https://docs.nvidia.com/networking-ethernet-software/cumulus-linux-44/Layer-3/Routing/Equal-Cost-Multipath-Load-Sharing-Hardware-ECMP/</nowiki>
| |
| − | | |
| − | If possible activate it per VRF, not globally, and restrict on dedicated subnets << depends of the vendor, it can be dangerous regarding memory management
| |
| − | | |
| − | | |
| − | | |
| − | Think at configuring the bgp option to not advertise routes to peers before they are installed in FIB.
| |
| − | | |
| − | | |
| − | We can implement leaf roles in some cases, to be able to do "light traffic engineering " on DCI links in some setup.
| |
| − | | |
| − | These roles will be managed within bgp communities added to VTEP /32. Look at the diagram below. Depending of the colour, the eBGP sessions between SupS will prepend or not the VTEP IPs announced to the remote DC

| − | This lab is a forked lab from many found on @, starting from Microsoft one : https://github.com/Azure/SONiC/wiki/SONiC-P4-Software-Switch
| |
| − | | |
| − | The target of this lab is to simulate a simple IP/Fabric in SPINE/LEAF topology. Each Leaf provide local L2 connectivity + L3 gateways to hosts. Flows between hosts from different leaf are L3 routed, in a "node path" LEAF-SPINE-LEAF.
| |
| − | | |
| − | Nothing complicated, but it allows to put a first foot into SONiC world :)
| |
| − | | |
| − | For the moment, as far as we know, MC-LAG + EVPN/VXLAN features are only available on entreprise SONiC versions. Tests to come once physic switches in enterprise version will be available in our lab.
| |
| − | | |
| − | The diagram of the architecture is into the zip file (SONIC_LAB.jpg)
| |
| − | | |
| − | To run the lab you need :
| |
| − | | |
| − | - to have installed docker by using ./install_docker_ovs.sh - to run the ./load_image.sh in order to get the Sonic image
| |
| − | | |
| − | Note : don't change file / folders names of network devices (leafX, spineX)
| |
| − | | |
| − | Once you're ready, please run the lab by launching "./start.sh"
| |
| − | | |
| − | The script :<div></div>
| |
| − | * launches the containers without Docket network features
| |
| − | * create network namespaces
| |
| − | * build linux bridges to interconnect the containers
| |
| − | * configure host IPs
| |
| − | * launch startup sonic scripts into sonic devices
| |
| − | * once devices started, checks + ping tests are run. If all BGP sessions are ok on spine + all ping are fine, the setup works well.
| |
| − | The "start" script has several comments, perhaps without the right vocabulary, so please be tolerant :)
| |
| − | | |
| − | If you want to stop the lab, please launch "./stop.sh"
