**Edit Policy OSPF Announce**
Item	Description
Id	A value that uniquely identifies the policy associated with this entry.
Name	An administratively-assigned name for this policy.
Enable	It indicates whether this policy is enabled or not. The policy should be applied only if it is set to 'true'.
ExactNetListId	Used to indicate the number of 'exact' type entries that are configured for this policy. An entry with type 'exactNet' or 'rangeNet' represents the network list. This indicates which networks will match a particular announce policy. An entry with a 'exact' type means to only match the specific network advertisement (netaddr & mask). An 'exact' entry with addr=0.0.0.0 and mask=0.0.0.0 means 'match the default route'. If set to '0', this policy applies to all the routes.
RangeNetListId	Used to indicate zero or more 'range' network entries that are associated with this policy. An entry with a 'range' type means to match any network number that falls in the range indicated by the addr & mask. A 'range' entry with addr=0.0.0.0 and mask=0.0.0.0 means 'match any route'. If set to '0', this policy applies to all the routes.
RipGatewayListId	Used to identify the RIP-gatewayList in the list that are associated with this policy. This field has meaning only for RIP sourced routes and if RIP is included as a RouteSource. The list contains one or more rip-routers (other side of the interface) addresses that could send RIP updates to this router. If a router address is included in this list, this policy applies to RIP advertisements from that router. If set to '0', this policy applies to RIP updates received from any rip routers/interfaces.
RipInterfaceListId	Used to indicate the number of entries in the ripInterfaceIdList that are configured for this policy. This field has meaning only for RIP sourced routes and if RIP is included as a RouteSource. The list contains one or more rip-interface addresses on this router. If an interface address is incuded in this list, this policy applies to RIP advertisements received on that interface. A value of '0' indicates thtat this policy applies to RIP updates received on any rip-interface.
Precedence	Is used while comparing this policy rule with other policy that a given route may match. A rule with a higher precedence value will be chosen over one with a smaller value. In the case of a tie, the PolicyId is used (larger wins).
RouteSource	Is represented as bit map to indicate route sources. It can contain one or more route sources. If the route source is in this bit map, then a route from that source that meets the other criteria of this policy will match the policy.
AdvertiseNetListId	Used to indicate the number of entries in the AdvertiseNetList that are configured for this policy. This has meaning only if the Action is set to 'announce'. It is useful to send or advertise networks that differ from actual network in the routing table. Also allows advertisement of an aggregate or default along with the actual network. Aggregation is useful if a number of routes in the table falls in a certain range. Can save space by sending aggregate route instead of the individual routes. Actual network/route is included in the update only if there is a match or there there is an entry (address & mask pair) 255.255.255.255/255.255.255.255 in the list.
Action	It indicates whether the route should be announced or not.
ExtMetricType	Ospf External metric type. It is used to indicate what type of the external metric it is. 'type1' means to the cost is 'internal ospf cost + ExtMetric'. 'type2' means the ospf-metric is equal to 'type2'.
ExtMetric	OSPF External metric. The value is meaningful only if the action is set to 'announce'. This is optional export metric to use when advertising a route that matches this policy. Value '0' is used to indicate that route's actual cost is used to announce.
