OpenStack Caracal : Neutron नेटवर्क (Geneve)2024/08/08 |
|
OpenStack नेटवर्क सेवा द्वारा वर्चुअल नेटवर्किंग कॉन्फ़िगर करें। (Neutron)
उदाहरण के लिए, यहां Geneve 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।

# ब्रिज जोड़ें ([br-eth1] के लिए कोई भी नाम जो आपको पसंद हो) root@network:~# ovs-vsctl add-br br-eth1
# पुल पर एक बंदरगाह जोड़ें # [eth1] को अपने परिवेश में बदलें root@network:~# ovs-vsctl add-port br-eth1 eth1
# पुल के लिए [physnet1] का नक्शा बनाएं ([physnet1] के लिए कोई भी नाम जो आपको पसंद हो) root@network:~# ovs-vsctl set open . external-ids:ovn-bridge-mappings=physnet1:br-eth1 |
| [2] | एक वर्चुअल राउटर बनाएं. किसी भी नोड पर काम करना ठीक है. (यह उदाहरण कंट्रोल नोड पर है) |

| [5] | डिफ़ॉल्ट रूप से, सभी परियोजनाओं के लिए केवल बाहरी नेटवर्क तक पहुंच संभव है, लेकिन आंतरिक नेटवर्क के लिए, केवल [admin] परियोजनाएं ही इस तक पहुंच सकती हैं, इसलिए जिस परियोजना में आप उपयोगकर्ताओं को प्रवेश देना चाहते हैं उसे आंतरिक नेटवर्क तक पहुंच की अनुमति दें परियोजना का उपयोग। |
