OpenStack Caracal : Neutron नेटवर्क (FLAT)2024/05/21 |
|
OpenStack नेटवर्क सेवा (Neutron) द्वारा वर्चुअल नेटवर्किंग कॉन्फ़िगर करें।
उदाहरण के लिए, यहां FLAT प्रकार की नेटवर्किंग कॉन्फ़िगर करें।
इसके अलावा, यह उदाहरण उस वातावरण पर आधारित है जिसमें नेटवर्क नोड और कंप्यूट नोड में 2 नेटवर्क इंटरफेस हैं।

# पुल जोड़ें root@network:~# ovs-vsctl add-br br-eth1
# उपरोक्त पुल के पोर्ट में [eth1] जोड़ें # इंटरफ़ेस नाम [eth1] को अपने परिवेश में बदलें root@network:~# ovs-vsctl add-port br-eth1 eth1
