Find the command in<br>> @commandtable near the end of the script, it points to the sub that<br>> parses that command. Edit the sub by putting your custom code in it<br>> somewhere reasonable:<br>> <br>> next if (/VRF table-id 0 not active/);<br>> <br>> Almost all reasonable rancid installations acquire a collection of<br>> customizations like this, it's how we users make rancid do what we need<br>> it to do :-)<br>> <br>> You might want to tweak that regex a bit more, eg the 0 so probably use<br>> a /d+, I will leave that up to you.<br>> <br>> <br>> <br>> <br>> On 03/02/2014 18:44, Peter Conrad wrote:<br>> > Hi, I have quite a few Cisco 4500-E switches running IOS XE.
