IP Router Configuration Command Reference
166 Router Configuration Guide
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 MPLS/RSVP 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 MPLS/RSVP will need to be re-added. If the no form of the command is executed
then ptp-hw-assist is disabled. If a new address is entered while another address is still active, the new
address will be rejected.
Default No IP address is assigned to the IP interface.
Parameters ip-address — The IP address of the IP interface. The ip-addr 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 1.0.0.0 to 223.255.255.255
/ — The forward slash is a parameter delimiter that separates the ip-addr portion of the IP address
from the mask that defines the scope of the local subnet. No spaces are allowed between the
ip-addr, the “/” and the mask-length parameter. If a forward slash does not immediately
follow the ip-addr, 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-addr 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 1— 32. A mask length
of 32 is reserved for system IP addresses.
Values 1 to 32
mask — The subnet mask in dotted decimal notation. When the IP prefix is not specified in CIDR
notation, a space separates the ip-addr 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. A mask of 255.255.255.255 is reserved for system IP
addresses.
Values 128.0.0.0 to 255.255.255.255
netmask — The subnet mask in dotted decimal notation.
Values 0.0.0.0 to 255.255.255.255 (network bits all 1 and host bits all 0)
broadcast {all-ones | host-ones} — The optional broadcast parameter overrides the default
broadcast address used by the IP interface when sourcing IP broadcasts on the IP interface. If
no broadcast format is specified for the IP address, the default value is host-ones,
which
indicates a subnet broadcast address. Use this parameter to change the broadcast address to
all-ones or revert back to a broadcast address of host-ones.
The all-ones keyword following the broadcast parameter specifies that the broadcast address
used by the IP interface for this IP address will be 255.255.255.255, also known as the local
broadcast.
