The following statement about isis protocol LSP messages is correct
A. The isP rapid diffusion feature, which first diffuses out LSPs that are smaller than a specified number , speeding up the synchronization process of LSDB
B. As link status information increases, the packet length of the LSP can be increased so that each ISP can carry more information.
C. By configuring an LSP-generated smart timer, the timer automatically adjusts the delay time based on the frequency at which the routing information changes
D. Reducing the minimum interval at which LSPs are sent per port can speed up the diffusion of LSPs.
