A. ISIS can choose whether to authenticate incoming SNP and LSP packets
B. If there are other vendors' devices on the network and do not support the LSP sharding function, the sharding expansion mode must be configured as Model-1, otherwise the message will not be recognized by other vendors' devices.
C. After you enable the LSP shard extension feature of your router, you can use it without restarting the ISIS process.
D. When the amount of information in the Link State Protocol data packet PDU to be released by ISIS is too large, the ISIS router will generate multiple LSP shards to carry more ISIS information.
