Cisco Bug: CSCul82468 - ASR1k GRE tunnel with tunnel protection doesn't check tunnel key
Dec 11, 2015
- Cisco IOS
Known Affected Releases
Symptom: On an ASR1000 series router, if a GRE tunnel interface is configured to have IPSec encryption using tunnel protection, then the tunnel key configured may not get checked for the incoming traffic post IPSec decapsulation. This can result in improper GRE decapsulation even though the tunnel keys don't match. Conditions: This only occurs when a tunnel key is configured.
