What is the function of BGP MD5 authentication, and what are functions of simple and cipher parameters

6

Border Gateway Protocol (BGP) message digest algorithm 5 (MD5) authentication sets MD5 authentication passwords for Transmission Control Protocol (TCP) connections to prevent TCP attacks.

The parameters simple and cipher in the peer { group-name | ipv4-address } password { cipher cipher-password | simple simple-password command only affect password display. The simple parameter indicates that the password is displayed in plain text. The cipher parameter indicates that the password is displayed in cipher text.

What are the functions of BGP MD5 authentication on S series switches
Q: What are the functions of BGP MD5 authentication, and the simple and cipher parameters? A: BGP MD5 authentication is designed to prevent TCP attacks. The MD5 password and TCP+BGP packets are input for calculation and then result A is saved in a TCP packet. The TCP peer resolves the result to check whether the TCP packet is a fake one. If so, it discards this TCP packet to guarantee stable TCP connection. The simple and cipher parameters only determine in which mode a password is displayed. If the simple parameter is configured, the password is displayed in plain text. If the cipher parameter is configured, the password is displayed in cipher text. If the same password is configured on both ends, the two ends adopt the same password for communication.

What's the function of pbx number-parameter?
If the trunk function is not used, change the dialup timer value of the AT0 trunk to 0. The AR does not need to spend 5s on detecting the ringback tone. A user needs to wait for only 3s to hear the ringback tone. Run the pbx number-parameter 40 0 command to set parameter 40 to 0. The modification may cause failures of calls transferred through trunks. The pbx number-parameter 40 0 command can be used only when POTS or SIP phones make outgoing calls through AT0 trunks.

What is the function of software parameter 286 of the U1900?
Software parameter 286 is used to determine whether the U1900 checks the SIP USER AGENT field during terminal registration. Specifically, this parameter determines whether non-Huawei terminals (third-party terminals) can register with the U1900.
