Refer to the exhibit. The router R1 and N9K1 establish EIGRP neighborship. R1 is advertising network 10.1.1.15/32 to N9K1 and N9K2 and N9K3 are forming the OSPF neighborship over area 1. Which…
The correct answer is A. N9K2(config-router)# area 1 stub no-summary. Configuring area 1 as a stub on N9K3 and as a totally stubby area (stub no-summary) on N9K2 prevents external LSAs (Type 5) from being injected into area 1. This blocks the advertisement of the external route (10.1.1.15/32) to N9K3.
