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?
