5.1是新出来的
5.1和4.5还是有区别的
5.1没有boot,service,standby network的概念了
IPAT and Service IP Labels
The following list summarizes how IPAT manipulates the service IP label:
When IPAT via IP Aliases is used
The service IP address/label is aliased onto the same network interface as an existing communications
interface.
That is, multiple IP addresses/labels are configured on the same network interface at the same time. In this
configuration, all IP addresses/labels that you define must be configured on different subnets.
This method can save hardware, but requires additional subnets.
When IPAT via IP Replacement is used
The service IP address/label replaces the existing IP address/label on the network interface.
That is, only one IP address/label is configured on the same network interface at the same time. In this
configuration, two IP addresses/labels on a node can share a subnet, while a backup IP address/label on the node must be on a different subnet.
This method can save subnets but requires additional hardware.
ip alias是新出来的概念，而且是缺省的配置。ip replace相当于老的4.5的概念 |
