Intra –protocol maintain network as single door admin only monitor traffic and no policy’s decisions are maintained. Intra- protocol mainly monitors the performance on network traffic.
Explanation:
Inter-protocols more end-user access internet so admin has monitor and check frequently network routing (how the network traffics are routed) and maintaining policy’s decisions.
