#2.
Depends - I believe by default L1/L2 is enabled on Juniper, therefore 2
adjacencies. Otherwise, if L1 only or if L2 only, then only a single
adjacency.

Subject: [j-nsp] isis question
hi all:
When I study isis, I meet the problem:
1 Which network layer use to encapsulation isis-pdu?
Is it clnp or ip?
CF: The OSI packets (or PDUs) are forwarded "as is" or transmitted directly
over the underlying link layer without the need for encapsulation - per RFC
1195.
2 How many IS-IS adjacency between point-to-point routers?
CF: IIH (IS-IS Hello) PDUs are utilized to initialize and maintain
adjacencies between neighbors. On a p2p link, one neighbor creates one
adjacency. Do you have a more specific question that needs answering?
