Please clarify[edit]

I am fairly experienced with networking concepts but I have no idea what NNIs are about despite having read this twice. The words used in the failed attempt at a definition contain way, way too many ambiguities. ‘Interface’ is one prime culprit. Giving truly concrete examples would also help but should not be the only means of giving a definition. The networks mentioned: IP is not an ‘interface’, neither is MPLS, nor SS7, they are protocols or protocol layers, or protocol specifications. Please help clarify this article.

Class 4 provider routers[edit]

I know how to configure MPLS P and PE routers but I do not recall reading anything about classes. What is a class 4 or higher provider router? The link to the provider router page did not provide an answer. 212.123.14.2 (talk) 11:02, 5 June 2023 (UTC)[reply]
