Release Information

Statement introduced in Junos OS Release 12.2.

Statement introduced in Junos OS Release 12.3 for ACX Series routers.


Configure a TCP session with a resource public key infrastructure (RPKI) cache server. The router-to-cache transport protocol is carried using a TCP session to a configurable port. Caches are organized in groups. The Junos OS implementation supports up to 63 sessions per group and both IPv4 and IPv6 address families.

The maximum number of sessions in a group is two, by default, and is configurable. If the number of sessions in a group exceeds the max-sessions value, the connections are established in order by preference value. A numerically higher preference results in a higher probability for session establishment. The order of session establishment is random among sessions with equal preferences.


address—IP address of the cache server.

The remaining statements are explained separately. See CLI Explorer.
