z/OS Communications Server: IP Messages Volume 4 (EZZ, SNM)
SC27-3657-01

EZZ8135I
DUE TO SUBNET MASK mask FROM type STATEMENT, IP ADDRESS ipaddr IS THE SUBNET BROADCAST ADDRESS

Explanation

An interface home address cannot be the same as its subnet broadcast address. The OMPROUTE configuration statement that matched the specified IP address included a subnet mask that violated this rule. The subnet broadcast address is obtained by logically ORing the IP address with the bit complement of the subnet mask. For example, the IP address 9.67.104.212 and the subnet mask 255.255.255.0 result in a subnet broadcast address of 9.67.104.255. In this example, the IP address 9.67.104.212 is not the same as subnet broadcast address 9.67.104.255, so the IP address can be used; however, the IP address 9.67.104.255 cannot be used because it is the same as the subnet broadcast address.

In the message text:

ipaddr
The IP address.
mask
The subnet mask value obtained from a statement in the OMPROUTE configuration file. The value was obtained from a statement of the type indicated by the type value. The statement was used for this interface because it explicitly specified the IP address or because it was specified with a wildcard value and the interface matched the wildcard value.
type
The type of OMPROUTE configuration statement from which the subnet mask was obtained. The value of type is either OSPF_Interface, RIP_Interface or Interface.

System action

OMPROUTE continues.

Operator response

None.

System programmer response

Change the value of the IP address in TCPIP, or in the OMPROUTE configuration file, or both, to be an address that is not the broadcast address for the subnet. Change the interface IP address value or subnet mask value so that the IP address is no longer the subnet broadcast address. You can change the IP address by modifying the TCPIP PROFILE configuration file, or the OMPROUTE configuration file. The subnet mask can be changed in the OMPROUTE configuration file.

User response

Not applicable.

Problem determination

Not applicable.

Module

EZAORCFG, EZAORYAC

Example

None.
