Opened: Aug 24, 2018
Severity: 2-Critical

Symptoms

Changing the policy mode for an IPsec tunnel can crash when switching back and forth between tunnel mode and interface mode.

Impact

A tmm restart, after a core, interrupts all IPsec tunnel service until new SAs are negotiated to replace the old ones.

Conditions

Changing mode in ipsec-policy from tunnel to interface, or vice versa.

Workaround

Start with desired mode, tunnel or interface, and avoid changing the value from one to the other.

Fix Information

None
