Severity: 1-Blocking


When the cmp-hash of the VLAN interface used by IKEv1 is set to non-default values (dst-ip or src-ip) for load-balancing IKEv1 traffic purposes; IKEv1 will fail.


IPsec does not work.


The VLAN interface used for IKEv1 traffic sets its cmp-hash value to non-default values.


Set the cmp-hash value of the VLAN interface for IKEv1 traffic to "default".

Fix Information

IKEv1 can re-establish its IKE SAs after the VLAN with IKEv1 traffic changes its cmp-hash setting (currently available options are "default, src-ip, dst-ip).
