# ocf\_heartbeat\_IPsrcaddr(7)

Manages the preferred source address for outgoing IP packets

## NAME

ocf\_heartbeat\_IPsrcaddr - Manages the preferred source address for outgoing IP packets

## SYNOPSIS

**IPsrcaddr** \[start \| stop \| monitor \| meta-data \| validate-all\]

## DESCRIPTION

Resource script for IPsrcaddr. It manages the preferred source address modification.

Note: DHCP should not be enabled for the interface serving the preferred source address. Enabling DHCP may result in unexpected behavior, such as the automatic addition of duplicate or conflicting routes. This may cause the IPsrcaddr resource to fail, or it may produce undesired behavior while the resource continues to run.

## SUPPORTED PARAMETERS

**ipaddress**

The IP address.

(required, string, no default)

**cidr\_netmask**

The netmask for the interface in CIDR format. (ie, 24), or in dotted quad notation 255.255.255.0).

(optional, string, no default)

**destination**

The destination IP/subnet for the route (default: 0.0.0.0/0)

(optional, string, default "0.0.0.0/0")

**proto**

Proto to match when finding network. E.g. "kernel".

(optional, string, no default)

**metric**

Metric. Only needed if incorrect metric value is used.

(optional, string, no default)

**pref**

IPv6 route preference (low, medium or high). Only needed if incorrect pref value is used.

(optional, string, no default)

**table**

Table to modify and use for interface lookup. E.g. "local".

The table has to have a route matching the "destination" parameter.

This can be used for policy based routing. See man [ip-rule(8)](/ip-rule/8.md).

(optional, string, no default)

**monitor**

Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 10s.

**validate-all**

Performs a validation of the resource configuration. Suggested minimum timeout: 5s.
