# Configure Calico Enterprise networking

## [📄️Configure BGP peering](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/bgp.md)

[Configure BGP peering with full mesh, node-specific peering, ToR, and/or Calico route reflectors.](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/bgp.md)

## [📄️Configure BGP peering with nested clusters running on KubeVirt VMs](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/bgp-to-workload.md)

[Configure BGP peering with nested clusters running on KubeVirt VMs](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/bgp-to-workload.md)

## [📄️Deploy a dual ToR cluster](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/dual-tor.md)

[Configure a dual plane cluster for redundant connectivity between workloads.](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/dual-tor.md)

## [📄️Configure multiple Calico Enterprise networks on a pod](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/multiple-networks.md)

[Configure a cluster with multiple Calico Enterprise networks on each pod, and enforce security using Calico Enterprise tiered network policy.](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/multiple-networks.md)

## [📄️Overlay networking](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/vxlan-ipip.md)

[Configure Calico to use IP in IP or VXLAN overlay networking so the underlying network doesn’t need to understand pod addresses.](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/vxlan-ipip.md)

## [📄️Advertise Kubernetes service IP addresses](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/advertise-service-ips.md)

[Configure Calico to advertise Kubernetes service cluster IPs and external IPs outside the cluster using BGP.](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/advertise-service-ips.md)

## [📄️Configure MTU to maximize network performance](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/mtu.md)

[Optimize network performance for workloads by configuring the MTU in Calico to best suit your underlying network.](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/mtu.md)

## [📄️Custom BGP configuration](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/custom-bgp-config.md)

[Customize your BGP configuration.](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/custom-bgp-config.md)

## [📄️Configure outgoing NAT](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/workloads-outside-cluster.md)

[Configure networking to perform outbound NAT for connections from pods to outside of the cluster.](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/workloads-outside-cluster.md)

## [📄️Use a specific MAC address for a pod](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/pod-mac-address.md)

[Specify the MAC address for a pod instead of allowing the operating system to assign one](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/pod-mac-address.md)

## [📄️Use NodeLocal DNSCache in your cluster](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/node-local-dns-cache.md)

[Install NodeLocal DNSCache](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/node-local-dns-cache.md)

## [📄️Configure QoS Controls](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/qos-controls.md)

[Configure QoS (Quality of Service) Controls to limit ingress and/or egress bandwidth, packet rate and number of connections of Calico workloads.](https://docs.tigera.io/calico-enterprise/3.21/networking/configuring/qos-controls.md)
