address command
Item Description
Syntax address ip-address[/mask]
no address
Context configure>service>vprn>interface
Description This command assigns an IP address, IP subnet, and broadcast address format to an 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 ISAM.
The local subnet that the address command defines must be part of the services address
space within the routing context using the configure router service-prefix command. The
default is to disallow the complete address space to services. Once a portion of the address
space is allocated as a service prefix, that portion can be made unavailable for IP interfaces
defined within the configure router interface CLI context for network core connectivity with
the exclude option in the configure router service-prefix command.
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
and 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.
The operational state is a read-only variable and the only controlling variables are the address
and admin states. The address and admin states are independent and can be set
independently. If an interface is in an adminstratively up state and an address is assigned, it
becomes operationally up and the protocol interfaces will be reinitialized (see Table 444).
Note: The ISAM supports configuration of IPv6 interfaces with a prefix length up to /126. The
ISAM does not support /127 addresses.
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.
Allowed values are IP addresses in the range 1.0.0.0 – 223.255.255.255 (with support of /31
subnets).
/ — The forward slash is a parameter delimiter and separates the ip-address portion of the IP
address from the mask that defines the scope of the local subnet. No spaces are allowed
between the ip-address, the "/" and the mask-length parameter. If a forward slash is not
immediately following the ip-address, a dotted decimal mask must follow the prefix.
mask-length — The subnet mask length when the IP prefix is specified in CIDR notation. When
the IP prefix is specified in CIDR notation, a forward slash (/) separates the ip-address from the
mask-length parameter. The mask length parameter indicates the number of bits used for the
network portion of the IP address; the remainder of the IP address is used to determine the
host portion of the IP address. Allowed values are integers in the range 0 – 30. Note that a
mask length of 32 is reserved for system IP addresses.
mask — The subnet mask in dotted decimal notation. When the IP prefix is not specified in
CIDR notation, a space separates the ip-address from a traditional dotted decimal mask. The
mask parameter indicates the complete mask that will be used in a logical 'AND' function to
derive the local subnet of the IP address. Allowed values are dotted decimal addresses in the
range 128.0.0.0 – 255.255.255.252. Note that a mask of 255.255.255.255 is reserved for
system IP addresses.
