Mind if I ask a noobie question?
How do you differeniate whether the DLCI is a gobal or local?
What I understand is local DLCI is locally significance.
If you refer to the printscreen attached from my CISCO Textbook, can you tell me how do you know whether the show comand can indicate whether it is a local or global DLCI.
Thank you for your time.
Yes, you are right. Frame relay router at customer's side won't show you whether it is local or global. Whether it is local or global DLCI, is normally determinted by the configuration on the frame relay switch (typically owned by Service Provider), ie: how it is configured on the Service Provider frame relay switch.
Here is a Cisco Press article on how local and global DLCI being configured on frame relay switch (Service Provider switch typically):
From the example on the global DLCI, DLCI: 101 is globally significant (again, as far as the Service Provider is concern).
Hope that answers your question.
