ChatGPT says: SOVC in the context of RPKI (Resource Public Key Infrastructure) on a Cisco router stands for "Stale Origin Validation Cache". RPKI is a security framework designed to secure the Internet's routing infrastructure, primarily through route origin validation. It ensures that the Internet number resources (like IP addresses and AS numbers) are used by the legitimate owners or authorized AS (Autonomous System). In RPKI, Route Origin Authorizations (ROAs) are used to define which AS is authorized to announce a specific IP address block. Network devices, like Cisco routers, use these ROAs to validate the authenticity of BGP (Border Gateway Protocol) route announcements. The term "stale" in SOVC refers to a situation where the router's RPKI-to-Router protocol client has lost its connection to the RPKI server, or when the RPKI cache data is outdated and not refreshed for some reason. This can happen due to network issues, configuration errors, or problems with the RPKI server itself. When the RPKI cache is stale, the router cannot reliably validate BGP route announcements against the latest ROA data, potentially affecting routing decisions. In a network security context, maintaining an up-to-date RPKI cache is crucial for ensuring that the network only accepts legitimate routing announcements, thereby reducing the risk of routing hijacks or misconfigurations. As a network security engineer, managing and monitoring the RPKI status on routers is an important aspect of ensuring network security and integrity.

You see SOVC mentioned, yes. But you don't see the word 'stale'. Please don't just paste what ChatGPT says. It's not an authoritative source. I can find no Cisco document stating what the acronym MEANS. But the context they use it seems to imply the word 'stale' isn't appropriate. A prefix or prefix range and the origin-AS corresponding to it are
considered an SOVC record. Overlapping prefix ranges are allowed. An SOVC table containing three records might look like this:
Valid—Indicates the prefix and AS pair are found in the SOVC table.
If more than one RPKI server is configured, the router will connect to all
configured servers and download prefix information from all of them. The SOVC table will be made of the union of all the records received from the different servers.
In the following example, the router is configured to connect to two RPKI servers, from which it will receive SOVC records of BGP prefixes and AS numbers.

SOVC appears to be a Cisco-specific acronym and it’s pretty certain that the OVC stands for Origin Validation Cache. My best intuition based on the research I’ve been able to do is that the S stands for Secure (on the pretense that RPKI and Origin Validation have something to do with security and because X.509 certificate and encryption and marketing buzzwords YAY!) Juniper refers to their equivalent database simply as “Route Validation (RV) Records in the RV Database. Hope that helps. Owen

If more than one RPKI server is configured, the router will connect to all configured servers and download prefix information from all of them. The SOVC table will be made of the union of all the records received from the different servers.
In the following example, the router is configured to connect to two RPKI servers, from which it will receive SOVC records of BGP prefixes and AS numbers.

ChatGPT says:
SOVC in the context of RPKI (Resource Public Key Infrastructure) on a Cisco router stands for "Stale Origin Validation Cache". RPKI is a security framework designed to secure the Internet's routing infrastructure, primarily through route origin validation. It ensures that the Internet number resources (like IP addresses and AS numbers) are used by the legitimate owners or authorized AS (Autonomous System).
In RPKI, Route Origin Authorizations (ROAs) are used to define which AS is authorized to announce a specific IP address block. Network devices, like Cisco routers, use these ROAs to validate the authenticity of BGP (Border Gateway Protocol) route announcements.
The term "stale" in SOVC refers to a situation where the router's RPKI-to-Router protocol client has lost its connection to the RPKI server, or when the RPKI cache data is outdated and not refreshed for some reason. This can happen due to network issues, configuration errors, or problems with the RPKI server itself. When the RPKI cache is stale, the router cannot reliably validate BGP route announcements against the latest ROA data, potentially affecting routing decisions.
In a network security context, maintaining an up-to-date RPKI cache is crucial for ensuring that the network only accepts legitimate routing announcements, thereby reducing the risk of routing hijacks or misconfigurations. As a network security engineer, managing and monitoring the RPKI status on routers is an important aspect of ensuring network security and integrity.

Greetings Am have tried to find out what is the abbreviation for SOVC with no luck. #sh bgp ipv4 unicast rpki servers BGP SOVC neighbor is X. X. X. 47/323 connected to port 323 Anyone have encountered this? Thanks!

I’m not sure what the acronym is, but I believe it’s an origin validator connection. (bap rpki server) Owen
