regexp - difference between ? and *
Hi Chee, With BGP perspective, Usually you use ? in the regular expression if you want to match only one more AS in the path , but you do not know what that AS could be, for example it could be 200 , 250, 50 and so on, and you do not want to match more than one AS , in this case you should use “?”. Again, think about it ? means Zero or one instance , which means either to match the absence of AS or to match the presence of one AS and stop there. * means is either no AS in the path or more than AS in the path , this is the reason we say Zero or more instances I prefer if you can revise IEWB , LAB 12, Task 5.8 , Brians did their best in a scenario with this keyword.
