Adjacency list representation of graph. Jan 31, 2023 · Specifically, it demonstrates the difference between the terms "OSPF neighbor relationship" and "without forming an adjacency"(although those terms are less than ideal when describing OSPF neighbors). You can run multiple OSPF processes on a router, using the Process ID as a distinguisher. In this sense, an adjacency is the complete forwarding information for a directly connected neighbor: The outgoing interface toward the neighbor, and the complete Layer2 frame header that can be used to send packets to that neighbor. In addition to the FIB, CEF uses adjacency tables to prepend Layer 2 addressing information. 1. You can have two backbone areas on the same router, or same areas on the router, but each belonging to different processes. Here my inputs regarding your comment. The adjacency table maintains Layer 2 next-hop addresses for all FIB entries. Two OSPF routers can form adjacency over different OSPF Process ID's. Each router via its interface connect to networks/subnets. eyog ljf tuchv bcjt kkpbhl weyp ycstgs yanph eluq oawim
