What is the first step in OSPFv3 neighbor discovery on a broadcast multi-access network?

Send hello packets to the AllSPFRouters multicast address

Flood link-state advertisements

You are troubleshooting an OSPFv3 adjacency issue between two Junos routers. The adjacency is stuck in the Init state. What is the most likely cause?

The routers have a mismatch in the OSPFv3 dead interval.

The routers are not receiving OSPFv3 Hello packets from each other.

The routers are in different OSPFv3 areas.

The routers have a mismatch in the OSPFv3 router ID.

Two Junos routers are configured for OSPFv3 on a point-to-point link. The OSPFv3 adjacency is stuck in the ExStart state. What is the most likely cause of this issue?

MTU mismatch between the two routers' interfaces.

The IPv6 link-local addresses are not configured on the interfaces.

The OSPFv3 router ID is not configured.

The routers are in different OSPFv3 areas.

A Junos router is running OSPFv3 and IS-IS for IPv6. Both protocols are advertising the same IPv6 prefix, 2001:db8:10::/64. The OSPFv3 route has a preference of 10, and the IS-IS route has a preference of 18. Which route will be installed in the routing table?

The IS-IS route, because it has a higher preference value.

The OSPFv3 route, because it has a lower preference value.

The route with the lower metric will be installed, regardless of preference.

Both routes will be installed, and load balancing will occur.
