You are bringing a new network online with three IS-IS routers using default Junos election priorities. The routers are configured as Level 2 only IS-IS routers.
Which statement is true about the DIS election in this scenario?
You are bringing a new network online with three IS-IS routers using default Junos election priorities. The routers are configured as Level 2 only IS-IS routers.
Which statement is true about the DIS election in this scenario?
In IS-IS (Intermediate System to Intermediate System) protocol, the Designated Intermediate System (DIS) is elected based on priority. By default, Junos routers have an election priority of 64. If there is a tie in the priority values, the router with the highest MAC address will be elected as the DIS. Therefore, the router with the highest MAC address will be elected as the DIS in this scenario.
Correct answer D Ref: https://www.juniper.net/documentation/us/en/software/junos/is-is/topics/concept/routing-protocol-is-is-security-designated-router-understanding.html
A router’s priority for becoming the designated router is indicated by an arbitrary number from 0 through 127, which you configure on the IS-IS interface. The router with the highest priority becomes the designated router for the area (Level 1, Level 2, or both), also configured on the IS-IS interface. If routers in the network have the same priority, then the router with the highest MAC address is elected as the designated router. By default, routers have a priority value of 64. D is correct Answer
