The IS-IS network layer protocol ID in the ISO protocol stack is 0x83. You can use router(config)# ip rsvp signalling rate-limit to limit the rate at which signaling messages are sent or use router(config-if)# hold-queue x in to limit the rate of reception.

This one can be done, you know We found that R2 can learn to R1 of the Loopback , R3 of the Loopback , and R3 directly connected interface routing of 34.0 , which is due to R4 pass R3 and R2 passed R3 of LSP did not carry the authentication information, then these LSPs to R3 after, R3 is definitely an error, so R3 will not flood the original LSP sent by R4 to R2 , and 3 will not flood the original LSP sent by R2 to R4 . However, R3 sends out its own LSP.There are R3 directly connected network segments 3.3.3.0 and 10.1.23.0 , 10.1.34.0 . These LSPs are flooded to R2 and R4 . Although LSPs carry TLV information for authentication , R2 and R4 do not open domain. Certification, so they directly ignore the certification information and then start reading LSP , which is the interpretation of the results of our experiments. Of course, if R2 and R4 are configured with domain-password but the password is different from other devices, then it goes without saying that directly discarding LSPs with different passwords will not be read at all.
