Which two types of IS-IS routers provide intra-area routing?

|
A Level 2 backbone.
|
|
|
what area number is assigned to an
IS-IS backbone. |

unbroken chain of Level 2 or Level 1/2 routers in order for the backbone to function. |
|
|

|
describe what an OSPF Router is doing in the init state?
|
It is awaiting a reply after it sends out its hello
|
|
|
What happens during the two-way state?
|
Once the router sees its own router ID in the list of neighbors, a neighbor relationship has been established and the router enters this state.

the DR sends out DDP's (database desc packets)
