SROS Command Line Interface Reference Guide PPP Interface Configuration Command Set

ip address <address> <mask> secondary

Use the ip address command to define an IP address on the specified interface. Use the optional secondary keyword to define a secondary IP address. Use the no form of this command to remove a configured IP address.

Syntax Description

<address>	Defines the IP address for the interface in dotted decimal notation (for example:
	192.22.73.101).
<mask>	Specifies the subnet mask that corresponds to the listed IP address.
secondary	Optional keyword used to configure a secondary IP address for the specified interface.

Default Values

By default, there are no assigned IP addresses.

Command Modes

(config-interface)#	Interface Configuration Mode required (applies to all physical interfaces as well as
	virtual interfaces)

Functional Notes

Use secondary IP addresses to allow dual subnets on a single interface (when you need more IP addresses than the primary subnet can provide). When using secondary IP addresses, avoid routing loops by verifying that all devices on the network segment are configured with secondary IP addresses on the secondary subnet.

Usage Examples

The following example configures a secondary IP address of 192.22.72.101/30:

(config)#interface ppp 1

(config-ppp 1)#ip address 192.22.72.101 255.255.255.252 secondary
