You configured interface ge-0/070.0 to run IS-IS. but this interface does not appear in the output of the show isis adjacency command as shown in the exhibit.
What is the problem in this scenario?
A.
This is a Gigabit Ethernet interface, that is incompatible with the reference-bandwidth 100g statement.
B.
The family iso statement must be added to the logical interface.
C.
The router at the other end of the link Is not sending any IS-IS Hello messages.
D.
The router at the other end of the link is a Level 1 only router.
For IS-IS to form adjacencies, the 'family iso' statement must be configured on the interface. This is required because IS-IS operates over the connectionless network service (CLNS) and not over IP. Without the 'family iso' configuration, IS-IS cannot form adjacencies over the interface.
