Context config>router>interface
Description This command assigns an IP address and IP subnet to an IP interface or enables the interface to accept
a dynamic IP address using DHCP. Only one IP address can be associated with an IP interface.
An IP address must be assigned to each IP interface. An IP address and a mask combine 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 router.
The IP address for the interface can be entered in either CIDR (Classless Inter-Domain Routing) or
traditional dotted-decimal notation. Show commands display CIDR notation and are stored in
configuration files.
By default, no IP address or subnet association exists on an IP interface until it is explicitly created.
The no form of the command removes the IP address assignment from the IP interface. Interface-
specific configurations for OSPF and MPLS/RSVP-TE are also removed. This will operationally stop
any MPLS LSPs that explicitly reference that IP address.
When a new IP address is defined, interface-specific configurations for OSPF and MPLS/RSVP-TE
must be added again.
If dynamic IP address assignment is enabled (using the dhcp keyword), the DHCP client ID (Option
61) and vendor class ID (Option 60) can be configured as specified in RFC 2132.
Default no address
Parameters ip-address — the IP address of the IP interface. The ip-address portion of the address command
/ — the forward slash is a parameter delimiter that separates the ip-address portion of the IP
mask — the subnet mask length when the IP prefix is specified in CIDR notation. When the IP
7705 SAR OS Router Configuration Guide
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
1.0.0.0 to 223.255.255.255
address from the mask that defines the scope of the local subnet. No spaces are allowed
between the ip-address, the "/" and the mask parameter. If a forward slash does not
immediately follow the ip-address, a dotted-decimal mask must follow the prefix.
prefix is specified in CIDR notation, a forward slash (/) separates the ip-address from the
mask parameter. The mask 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.
Values
1 to 32 (mask length of 32 is reserved for system IP addresses)
