I found a document on internet that will give some idea on OSPF ABR and Loop Prevention. In that document, they mention This: ABR expects summary LSAs from Area 0 only. This means there should be at least one adjacency in FULL state built over Area 0 interface. In case if ABR has such adjacency, it will ignore summary-LSAs received over non ... Am using open source OSPF software from ospf.org and running ospf daemon in host PC. If router has interfaces in multiple area, then its an Area Border Router. Is there a way to detect the router is ASBR in OSPF ? Is the Network Planner explicitly tell the router would be an ASBR router,while configuring the network. Now within the scope of OSPF, think of the E2 route selection process: OSPF chooses the best exit point based on the external metric and uses the internal cost to ASBR as a tie breaker. In other words, OSPF performs “cold potato” routing with respect to E2 prefixes. It is easy to turn this process into “hot potato” by ensuring that every exit point uses the same E2 metric value. It is ... The OSPF ASBR creates these LSAs and they are sent to the Area Border Routers for dissemination into the other areas. Remember, this might change if we are using special area types. The NSSA External (Type 7) LSA. Remember that in OPSF there is a VERY special area type called a Not So Stubby Area. This area can act stub, but it can also bring in external prefixes from an ASBR. You guessed it ...
