The verify-source command enables check on source IP addresses in RIP Update packets.
The undo verify-source command disables check on source IP addresses in RIP Update packets.
By default, the source IP addresses in RIP Update packets are checked.
Usage Scenario
After the verify-source command is executed, RIP checks whether the IP addresses of interfaces that send and receive the Update packets are on the same network segment. If not, the device does not process the packets.
It is not recommended that you disable source address check.
