Description
If the keys used for routing protocol authentication are guessed, the malicious user could create havoc within the network by advertising incorrect routes and redirecting traffic. Changing the keys frequently reduces the risk of them eventually being guessed. When configuring authentication for routing protocols that provide key chains, configure two rotating keys with overlapping expiration dates, both with 180-day or less expirations.

Check Text ( C-12696r5_chk )
Review device configuration for key expirations of 180 days or less. If rotating keys are not configured to expire at 180 days or less, this is a finding.

Fix Text (F-14125r4_fix)
Configure the device so rotating keys expire at 180 days or less.
