Consider an OSPFv3 network with four parallel links between each pair of routers. Which measure
can you use to reduce the CPU load and at the same time keep all links available for ECMP?
A.
Configure some interfaces as passive interface.
B.
Configure ipv6 ospf priority 0 on some interfaces.
C.
Configure some routers with a distribute list in ingress of the OSPFv3 process.
D.
Configure ipv6 ospf database-filter all out on some interfaces.
Since the OSPF LSA Database must match between routers in the same area, there is no reason to send the same LSA database multiple times over four parallel links. In practice, I wouldn’t do this…
