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


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


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


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