Figure 7.4 TRIP: LS tells peers their initial data

When an LS receives data from a peer LS, it stores it internally.This data is distributed the next time the LS sends an UPDATE message to its peers, but not before a minimum delay has elapsed (see Figure 7.5). Each node can decide whether to advertise itself (or better: the associated VoIP

server) as the next-hop server of the new learned numbers (Node D) or to pass the information of the original contact (Node C).
