Two AOS-Switches connect on VLAN 10 in OSPF Area 1, which is defined as a stub area on both. Which mismatch can cause OSPF routers to lose adjacency?
Two AOS-Switches connect on VLAN 10 in OSPF Area 1, which is defined as a stub area on both. Which mismatch can cause OSPF routers to lose adjacency?
For OSPF routers to form and maintain an adjacency, several parameters must match, including the Area ID, OSPF Process ID, Timers, Network Type, IP Subnet, and MTU (Maximum Transmission Unit). Enabling jumbo frames on VLAN 10 for just one of the routers would cause a mismatch in the MTU setting, which would prevent the OSPF routers from maintaining adjacency. Therefore, the mismatch in MTU can disrupt the OSPF adjacency.
i bet C
MTU must be the same on the routers
C is the answer
C. To form an adjacency the following must match: Area ID, OSPF Process ID,Timers, Network Type, IP Subnet, and MTU Changing any of these attributes disable the adjacency
Concur with C. MTU is basic adjacency requirement.
I think correct answer is A
B. gracefull restart
