Syntax address {ip-address/mask | ip-address netmask} [broadcast {all-ones | host-ones}]

Context config>service>vprn>interface
Description This command assigns an IP address, IP subnet, and broadcast address format to a VPRN IP router
interface. Only one IP address can be associated with an IP interface.
An IP address must be assigned to each VPRN IP interface. An IP address and a mask are used
together to create a local IP prefix. The defined IP prefix must be unique within the context of the
routing instance. It cannot overlap with other existing IP prefixes defined as local subnets on other IP
interfaces in the same routing context within the 7705 SAR.
The IP address for the interface can be entered in either CIDR (Classless Inter-Domain Routing) or
traditional dotted-decimal notation. The show commands display CIDR notation, which is stored in
configuration files.
By default, no IP address or subnet association exists on an IP interface until it is explicitly created.
Use the no form of this command to remove the IP address assignment from the IP interface. When
the no address command is entered, the interface becomes operationally down, as shown in
Table 57.
The operational state is a read-only variable, and the only controlling variables are the address and
administrative states. The address and administrative states are independent and can be set
independently. If an interface is in an administratively up state and an address is assigned, it becomes
operationally up and the protocol interfaces and the MPLS LSPs associated with that IP interface will
be reinitialized.
Parameters ip-address — the IP address of the IP interface. The ip-address portion of the address command
specifies the IP host address that will be used by the IP interface within the subnet. This address
must be unique within the subnet and specified in dotted-decimal notation.
Values a.b.c.d (no multicast address)
