# Pathvector Calico Plugin
The `calico` plugin adds support for Calico BGP autoconfiguration to Pathvector version 6.
## Quickstart
For this example, we'll use a single node k3s cluster with Pathvector running on the host itself. In a real network, your cluster would have more than one node and Pathvector would run on the network device (ToR switch, core router, etc).
### Install Calico on k3s
Follow the [Calico k3s quickstart](https://docs.projectcalico.org/getting-started/kubernetes/k3s/quickstart) to spin up a single node development cluster:
```bash
# Install k3s with default Flannel CNI disabled
curl -sfL https://get.k3s.io | K3S_KUBECONFIG_MODE="644" INSTALL_K3S_EXEC="--flannel-backend=none --cluster-cidr=192.168.0.0/16 --disable-network-policy --disable=traefik" sh -
# Install the Calico operator and custom resource definitions
kubectl create -f https://docs.projectcalico.org/manifests/tigera-operator.yaml
kubectl create -f https://docs.projectcalico.org/manifests/custom-resources.yaml
# Deploy the calicoctl container to connect to the Kubernetes API datastore
kubectl apply -f https://docs.projectcalico.org/manifests/calicoctl.yaml
# Alias calicoctl to the calicoctl container
alias calicoctl='kubectl exec -i -n kube-system calicoctl -- /calicoctl'
```
Run `watch kubectl get pods --all-namespaces` and wait for everything to start up.
```bash

### Add a global BGP peer
```bash
cat <> calico-bgp.yaml
apiVersion: projectcalico.org/v3
kind: BGPPeer
metadata:
name: pathvector-upstream
spec:
peerIP: 127.0.0.2
asNumber: 65530
EOT
kubectl apply -f calico-bgp.yaml
```
