IP Router Configuration Command Reference
116 Router Configuration Guide
Default The system uses the system interface address (which is also the loopback address).
If a system interface address is not configured, use the last 32 bits of the chassis MAC address.
Parameters router-id — The 32 bit router ID expressed in dotted decimal notation or as a decimal value.
service-prefix
Syntax service-prefix ip-prefix/mask | ip-prefix netmask [exclusive]
no service-prefix ip-prefix/mask | ip-prefix netmask
Context config>router
Description This command creates an IP address range reserved for IES or VPLS services.
The purpose of reserving IP addresses using service-prefix is to provide a mechanism to reserve one
or more address ranges for services.
When services are defined, the address must be in the range specified as a service prefix. If a service
prefix is defined, then IP addresses assigned for services must be within one of the ranges defined in
the service-prefix command. If the service-prefix command is not configured, then no limitations
exist.
Addresses in the range of a service prefix can be allocated to a network port unless the exclusive
parameter is used. Then, the address range is exclusively reserved for services.
When a range that is a superset of a previously defined service prefix is defined, the subset is replaced
with the superset definition; for example, if a service prefix exists for 10.10.10.0/24, and a service
prefix is configured as 10.10.0.0/16, then 10.10.10.0/24 is replaced by the new 10.10.0.0/16
configuration.
When a range that is a subset of a previously defined service prefix is defined, the subset replaces the
existing superset, providing addresses used by services are not affected; for example, if a service prefix
exists for 10.10.0.0/16, and a service prefix is configured as 10.10.10.0/24, then the 10.10.0.0/16 entry
is removed as long as no services are configured that use 10.10.x.x addresses other than 10.10.10.x.
The no form of the command removes all address reservations. A service prefix cannot be removed
while one or more service uses an address or addresses in the range.
Default no service-prefix - no IP addresses are reserved for services.
Parameters ip-prefix/mask — The IP address prefix to include in the service prefix allocation in dotted
decimal notation.
