Match any of the characters between the brackets “ab+c” matches abc, abbc, abbbc and so on Match preceding character one or more times “ab*c” matches ac, abc, abbc, abbbc and so on Match preceding character zero or more times “a.c” matches aac, abc, acc, a1c, a2c and so on Let’s see some rules for the search pattern first.

However, combined with a “replace” pattern, it becomes even more useful. 3 Generate Tabular Data from ConfigurationĪ regular expression defines a search pattern.2 Generate Configuration from Tabular Data.Ok, enough of the need for regular expressions (regex), let’s get started. Let’s keep that for some other day and talk about simple config generation on a single device that we can manually apply.

While automation can go a long way where we can have multiple devices or device groups, automated login to these, implementation of config and finally verification of status and rollback if needed, all being launched in order by a single orchestrating script – say an Ansible Playbook.

This is a type of automation as we aim to reduce if not eliminate manual processes that are very well defined and certainly repeatable. This may also be true for a junior network engineer who may not know other efficient methods of achieving it. How do you implement it on the device?įor small and non-routine one-off tasks, the quickest way may be to jump on the device and repeat the manual labor N times at different places and with slight variations, where N is hopefully a relatively small number worth this manual approach. How many times were you working on a task which involved either updating all instances of a piece of configuration or creating a new configuration piece at multiple points on a network device? You have translated the requirements into functional syntax, a blueprint, for the specific hardware platform, now it’s time to implement it 10’s of times on the device.
