BGP route leak prevention by using BGP roles and OTC attributes based on RFC 9234 (cRPD, MX204, MX240, MX301, MX304, MX480, MX960, MX10004, MX10008, MX2008, MX2010, and MX2020)—You can prevent route leaks in BGP routing by using BGP roles and OTC attributes as defined in RFC 9234. The feature ensures that routes from providers or peers are only propagated to customers, reducing misconfigurations and errors. The BGP speaker automatically sets the OTC based on its configured role, and then advertises a prefix based on the OTC presence in the BGP update message, making the configuration straightforward and minimizing manual intervention. With this feature, you can maintain intended routing policies and prevent network delays and denial-of-service (DoS) attacks.
