Enforcing configuration standards through commit scripts
In this recipe, we'll look at how we improve the security and stability of our network environment by ensuring that configuration standards are maintained and that common configuration errors are detected and prevented by the JUNOS system.
Getting ready
In order to complete this recipe, you just need access to a working JUNOS system that you can configure and upon which you can deploy SLAX scripts.
We will implement logic on the JUNOS device that prevents the following situations from occurring, thus warning the operator about the problem.
- Loopback interface deletion: The loopback interface often acts as a system identifier for some protocols and features and so deletion or deactivation of the loopback address creates a problematic situation
- Internal ISIS/OSPF interface deletions: The interior gateway protocol is usually a fundamental mainstay of the network topology and configurations that remove interfaces from a working ISIS or OSPF...
