Creating an IP Address Range

An IP address range can be reserved for exclusive use for services by defining the
config>router>service-prefix command. When the service is configured, the IP address must
be in the range specified as a service prefix. If no service prefix command is configured, then
no limitation exists.
The no service-prefix ip-prefix/mask command removes all address reservations. A service
prefix cannot be removed while one or more services use address(es) in the range to be
removed.
CLI Syntax:

Deriving the Router ID

The router ID defaults to the address specified in the system interface command. If the system
interface is not configured with an IP address, then the router ID inherits the last four bytes
of the MAC address. The router ID can also be manually configured in the config>router
router-id context. On the BGP protocol level, a BGP router ID can be defined in the
config>router>bgp router-id context and is only used within BGP.
If a new router ID is configured, protocols are not automatically restarted with the new router
ID. The next time a protocol is initialized the new router ID is used. An interim period of time
can occur when different protocols use different router IDs. To force the new router ID, issue
the shutdown and no shutdown commands for each protocol that uses the router ID, or restart
the entire router.
It is possible to configure an SR OS node to operate with an IPv6 only BOF and no IPv4
system interface address. When configured in this manner, the operator must explicitly define
IPv4 router IDs for protocols such as OSPF and BGP as there is no mechanism to derive the
router ID from an IPv6 system interface address.
