Usage Guide
For OSPF, the source address of the received packet is required to be in the same network segment
with the receiving interface. However, in a point-to-point link, the addresses of two ends of the link are
individually set, and they are not required to be in the same network segment. The peer address is
informed during the process of point-to-point link negotiation; therefore, OSPF will check whether the
source address of the packet is the informed one. If no, the OSPF regards this packet as illegal and
drops it. In some applications, the addresses informed during the negotiation are shielded. You need
to disable the source address check to ensure the normal establishment of OSPF neighbors. The
source address check shall be never enabled, especially for the unnumbered interfaces.
Configuration
Examples
The following example disables the source address check function in the point-to-point link.
Ruijie(config)# interface serial
1/0
Ruijie(config-if)# ip ospf source-check-ignore
