VPLS Service Configuration Commands
The local subnet that the address command defines must be part of the services address space within
the routing context using the config 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 config router
interface CLI context for network core connectivity with the exclude option in the config 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 and the MPLS LSPs associated with that IP interface will be reinitialized.
ip-address — The IP address of the IP interface. The ip-address portion of the address command
arp-timeout
Syntax arp-timeout seconds
no arp-timeout
Context config>service>vpls>interface
Description
This command configures the minimum time in seconds an ARP entry learned on the IP interface will
be stored in the ARP table. ARP entries are automatically refreshed when an ARP request or
gratuitous ARP is seen from an IP host, otherwise, the ARP entry is aged from the ARP table. If arp-
timeout is set to a value of zero seconds, ARP aging is disabled.

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
netmask
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.
