IP Router Configuration
Router Configuration Guide 115
Description This command configures a static VRP entry indicating that a particular origin AS is either valid or
invalid for a particular IP prefix range. Static VRP entries are stored along with dynamic VRP entries
(learned from local cache servers using the RPKI-Router protocol) in the origin validation database of
the router. This database is used for determining the origin-validation state of IPv4 and/or IPv6 BGP
routes received over sessions with the enable-origin-validation command configured.
Static entries can only be configured under the config>router>origin-validation context of the base
router.
Default no static entries
Parameters ip-prefix/ip-prefix-length — Specifies an IPv4 or IPv6 address with a minimum prefix length
value.
Values 60 to 3600
prefix-length2 — Specifies the maximum prefix length.
as-number — Specifies as-number.
Values 0 to 4294967295
valid — Specifies a keyword meaning the static entry expresses a valid combination of origin AS
and prefix range.
invalid — Specifies a keyword meaning the static entry expresses an invalid combination of
origin AS and prefix range.

Description This command configures the router ID for the router instance.
The router ID is used by both OSPF and BGP routing protocols in this instance of the routing table
manager. IS-IS uses the router ID value as its system ID.
When configuring a new router ID, protocols are not automatically restarted with the new router ID.
The next time a protocol is initialized, the new router ID is used. This can result in an interim period
of time when different protocols use different router IDs.
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.
To force the new router ID to be used, issue the shutdown and no shutdown commands for each
protocol that uses the router ID, or restart the entire router.
The no form of the command to reverts to the default value.
