As a result of a known issue the dynamic routing protocol daemon ripd, used for the RIP protocol may produce a core file when configuring it to use a interface configured with multiple self IP addresses on different subnets on the same VLAN.
ripd will core and the configuration will not be allowed.
- Use the RIP dynamic routing on an affected version. - Have multiple self IP addresses belonging to different subnets on the same VLAN - Add one of the subnets with the network command within the "router RIP" stanza.
Configure one subnet/self IP address per VLAN.
ripd no longer cores when configured with multiple subnets on the same VLAN.
