Does an S series switch support BGP
BGP support varies depending on S series switches, which is listed as follows (until V200R008): - S7700/S9700/S12700: supported - S9300: supported - S6720EI: supported - S6700EI: supported - S5720HI: supported - S5710HI: supported - S5700HI: supported - S5720EI: supported - S5710EI: supported - S5700EI: supported - S5720SI/S5720S-SI: supported - S5700SI: not supported - S5710LI: not supported - S5700LI: not supported - S5700S-LI: not supported - S3700HI: supported - S3700EI: supported - S3700SI: not supported - S2750EI: not supported - S2720EI: not supported - S2700EI: not supported - S2710SI: not supported - S2700SI: not supported - S1720: not supported BGP4+ support varies depending on S series switches, which is listed as follows (until V200R008): - S7700/S9700/S12700: supported - S9300: supported - S6720EI: supported - S6700EI: supported (V200R001 and later) - S5720HI: supported - S5710HI: supported - S5700HI: supported (V200R001 and later) - S5720EI: supported - S5710EI: supported - S5700EI: supported (V200R001 and later) - S5720SI/S5720S-SI: supported - S5700SI: not supported - S5710LI: not supported - S5700LI: not supported - S5700S-LI: not supported - S3700HI: supported (V200R001 and later) - S3700EI: not supported - S3700SI: not supported - S2750EI: not supported - S2720EI: not supported - S2700EI: not supported - S2710SI: not supported - S2700SI: not supported - S1720: not supported

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 is the value range of the AS number for BGP on S series switches
The value range of the BGP AS number varies according to the versions of S series switches. 1. V100R002 and earlier versions: The value is an integer that ranges from 1 to 65535. 2. V100R003 to V200R001: The value can contain either two bytes or four bytes. A 2-byte AS number is in the x format. Here, "x" is an integer ranging from 1 to 65535. A 4-byte AS number is in the x.y format. Here, "x" and "y" are integers ranging from 1 to 65535 and 0 to 65535 respectively. 3. V200R002 and later versions: The value can contain either two bytes or four bytes. A 2-byte AS number is in the x format. Here, "x" is an integer ranging from 1 to 4294967295. A 4-byte AS number is in the x.y format. Here, "x" and "y" are integers ranging from 1 to 65535 and 0 to 65535 respectively. Note: You can type bgp ? in the system view in any version to display the specific value range. The following takes V200R007 as an example: [SwitchA] bgp ? INTEGER<1-4294967295> AS number in asplain format (number<1-4294967295>) STRING<3-11> AS number in asdot format (number<1-65535>.number<0-65535>)

On S series switches, how long does it take for BGP routes to expire after the static routes imported by BGP expire
If the static routes imported by an S series switch become invalid, the routes imported in the BGP routing table will be invalidated. The route imported through the network command must be active in the local routing table. Otherwise, it cannot be imported in the BGP routing table.
