利用ODL建立VxLAN網路
說明：mininet1（192.168.1.209），mininet2（192.168.1.211），odl（192.168.1.217）為三臺虛機，在同一網段，其中odl虛機安裝了opendaylight-boron-sr3，mininet1和mininet2都安裝了mininet
1.讓mininet1和mininet2連結上odl，並設定manager
mininet1和mininet2進行操作（這裡是設定監聽管理埠）：
sh ovs-vsctl set-manager ptcp:6640說明：下面的remote-ip為需要設定manager的mininet的ip
ODL主機發送以下Rest請求到mininet1:
url:http://192.168.1.217:8181/restconf/config/network-topology:network-topology/topology/ovsdb:1/node/ovsdb:%2F%2FHOST1
Method:PUT
Bady:
{
"node": [
{
"node-id": "ovsdb://HOST1",
"ovsdb:connection-info": {
"remote-ip": "192.168.1.209",
"remote-port": "6640"
}
}
]
}ODL主機發送以下Rest請求到mininet2:
url:http://192.168.1.217:8181/restconf/config/network-topology:network-topology/topology/ovsdb:1/node/ovsdb:%2F%2FHOST2
Method:PUT
Bady:
{
"node": [
{
"node-id": "ovsdb://HOST2",
"ovsdb:connection-info": {
"remote-ip": "192.168.1.211",
"remote-port": "6640"
}
}
]
}2.建立網橋
在HOST1上建立網橋：
url:http://192.168.1.217:8181/restconf/config/network-topology:network-topology/topology/ovsdb:1/node/ovsdb:%2F%2FHOST1%2Fbridge%2Fbrtest
Method:PUT
Body:
{
"node": [
{
"node-id": "ovsdb://HOST1/bridge/brtest",
"ovsdb:bridge-name": "brtest",
"ovsdb:protocol-entry": [
{
"protocol": "ovsdb:ovsdb-bridge-protocol-openflow-13"
}
],
"ovsdb:managed-by": "/network-topology:network-topology/network-topology:topology[network-topology:topology-id='ovsdb:1']/network-topology:node[network-topology:node-id='ovsdb://HOST1']",
"hwvtep:managed-by": "/network-topology:network-topology/network-topology:topology[network-topology:topology-id='ovsdb:1']/network-topology:node[network-topology:node-id='ovsdb://HOST1']"
}
]
}在HOST2上建立網橋：
url:http://192.168.1.217:8181/restconf/config/network-topology:network-topology/topology/ovsdb:1/node/ovsdb:%2F%2FHOST2%2Fbridge%2Fbrtest
Method:PUT
Body:
{
"node": [
{
"node-id": "ovsdb://HOST2/bridge/brtest",
"ovsdb:bridge-name": "brtest",
"ovsdb:protocol-entry": [
{
"protocol": "ovsdb:ovsdb-bridge-protocol-openflow-13"
}
],
"ovsdb:managed-by": "/network-topology:network-topology/network-topology:topology[network-topology:topology-id='ovsdb:1']/network-topology:node[network-topology:node-id='ovsdb://HOST2']",
"hwvtep:managed-by": "/network-topology:network-topology/network-topology:topology[network-topology:topology-id='ovsdb:1']/network-topology:node[network-topology:node-id='ovsdb://HOST2']"
}
]
}3.建立埠
說明：mininet1中body裡面value的值為mininet2的ip
在mininet1上建立vxlan port：
url:http://192.168.1.217:8181/restconf/config/network-topology:network-topology/topology/ovsdb:1/node/ovsdb:%2F%2FHOST1%2Fbridge%2Fbrtest/termination-point/testport
Methos:put
Body:
{
"termination-point": [
{
"tp-id": "testport",
"ovsdb:name": "testport",
"ovsdb:interface-type": "ovsdb:interface-type-vxlan",
"ovsdb:options": [
{
"option": "remote_ip",
"value": "192.168.1.211"
}
]
}
]
}在mininet2上建立vxlan port：
url:http://192.168.1.217:8181/restconf/config/network-topology:network-topology/topology/ovsdb:1/node/ovsdb:%2F%2FHOST2%2Fbridge%2Fbrtest/termination-point/testport
Methos:put
Body:
{
"termination-point": [
{
"tp-id": "testport",
"ovsdb:name": "testport",
"ovsdb:interface-type": "ovsdb:interface-type-vxlan",
"ovsdb:options": [
{
"option": "remote_ip",
"value": "192.168.1.209"
}
]
}
]
}4.給mininet1和mininet2中的網橋設定ip（命令列執行：ifconfig brtest 30.0.0.3/8 up和ifconfig brtest 30.0.0.2/8 up）
（ip為同子網不需要設定路由，非同子網自行設定路由）
5.驗證：
在mininet1上用ping測試：ping 30.0.0.2
注意：要麼同時odl發指令，要麼同時手動配，否則建立的vxlan是無法通訊的
