In this chapter, we learned how to interact with Network devices through Python. We got familiar with an extensively used library of Python (Netmiko) for network interactions. Readers also got an insight into how to interact with multiple network devices using a simulated lab in GNS3 through examples on config generation and implementation through network templates.
Additionally, we also got to know the device interaction through SNMP, which is an industry standard method of interaction with various infrastructure devices. Using examples, we saw how to fetch types of devices as well as interface stats on each router in a quick and efficient manner.
Additionally, we also touched base on multithreading, which is a key component in scalability through various examples. To sum this aspect up, we saw certain use cases that are a real-life challenge for any network engineer...
