Hi,
I have 2 lists list1 and list2. I need to allow an element in list2, only if the same element is present in list1. I tried re-match, however, when i do this within list2, i end up checking only the 1st element of list2 being present in the first element of list1. I am unable to do for the current element.
Any pointers please ?
Thanks,
Rajiv
I think leafrefs is what you are looking for.
See section 9.9. The leafref Built-In Type in RFC 7950 and section 3.10 and 3.11 in the UG.
The YANG-model below is further explained in section 3.10.
module links {

type empty;
}
leaf BROADCAST {
type empty;
}
leaf MULTICAST {
type empty;
}
leaf LOOPBACK {
type empty;
}
leaf NOTRAILERS {
type empty;
}
}
typedef QueueDisciplineType {
