Description (partial)


'Preview Configuration' operations reports an internal error, when some changes are made in the overridden 'Policy objects' used in router policy.


This problem is seen only rarely, also in a spefic flow. A particular way in which the problem could be seen as following.
Import two ISR routers into the CSM.
Open 'Policy Object Manager' and create a network object, say 'net1' and while creating this object, instead of specifying an IP, choose to select another network object which would be contained in it. Do not select any existing network object but create a new network object, say 'net2'. Make 'net2' overridable in the same flow and add the two routers imported earlier and give different IP's for both those routers. Close 'net2'. 'net1' and 'Policy Object Manager'.
Use 'net1' in any router policy in the router.
Select the same router and select 'Preview Configuration'.
Sometimes there will be an 'Internal Error' reported after this.
