calico网络 ipip改为BGP模式

标签：ipip BGP location https com calico

calico网络 包含 overlay  和 underlay网络

overlay   IPIP和VXLAN模式，  IPIP可以使用BGP协议， VXLAN不能使用BGP协议， 可以跨网段，建立隧道

underlay BGP模式， 必须同一个C网

1、修改ippool，需要把ipipMode从Always修改成为Never（执行下面命令修改ipipMode）。

[root@k8s-master1 target]# kubectl edit ippool
ipipMode: Never

2. 关闭 ipip模式， 定义asnumber 自治网络号。

 

cat << EOF | calicoctl create -f -
 apiVersion: projectcalico.org/v3
 kind: BGPConfiguration
 metadata:
   name: default
 spec:
   logSeverityScreen: Info
   nodeToNodeMeshEnabled: false
   asNumber: 64512
EOF

 

3.  指定反射器地址。

 

cat << EOF | calicoctl create -f -
apiVersion: projectcalico.org/v3
kind: BGPPeer
metadata:
  name: bgppeer-global-55
spec:
  peerIP: 192.168.15.55
  asNumber: 64512
EOF
