1.35 validate-update-source
Use this command to validate the source address of the received RIP route update packet. Use the
no form of the command to disable this function.
no validate-update-source
This function is enabled by default.
Routing process configuration mode
You can validate the source address of the RIP route update packet. The validation aims to ensure
that the RIP routing process receives only the route update packets from the same IP subnet
neighbor.
Disabling split horizon on the interface causes the RIP routing process to enable update message
source address validation, no matter whether it has been configured with the
validate-update-source command in routing process configuration mode.
In addition, for the ip unnumbered interface, the RIP routing process does not implement update
message source address validation, no matter whether it has been configured with the command
validate-update-source.
The following example disables verification of the source IP address of the update packet.
Ruijie (config)# router rip
Ruijie (config-router)# no validate-update-source
Defines the IP unnumbered interface.
Defines the IP address of a RIP neighbor.
