What is the order of the OSPF States?

​ Down, ​ (a)   , ​ (b)   , ​ (c)   , ​ (d)   , ​ (e)   , Full

• Init
• Two-Way
• ExStart
• Exchange
• Loading

Which descriptions matches the Init State?

• the link-state database of the router is fully synchronized.

• router with the highest router ID will initiate the DBD (Database Description) exchange.

• Hello packets are sent/received to establish neighbor adjacencies.

• elect a DR and BDR

• routers exchange DBD packets (DBD is an abbreviated list of the LSDB sent by a neighboring router and is used by receiving routers to check against the local LSDB)

Which descriptions matches the ExStart State?

• the link-state database of the router is fully synchronized.

• router with the highest router ID will initiate the DBD (Database Description) exchange.

• Hello packets are sent/received to establish neighbor adjacencies.

• elect a DR and BDR

• routers exchange DBD packets (DBD is an abbreviated list of the LSDB sent by a neighboring router and is used by receiving routers to check against the local LSDB)

Which descriptions matches the Two-Way State?

• routers exchange DBD packets (DBD is an abbreviated list of the LSDB sent by a neighboring router and is used by receiving routers to check against the local LSDB)

Which descriptions matches the Loading State?
