* ABR Address: specifies the interface address that the ABR uses to connect to the area. An
ABR is a router that connects multiple areas.
* Authentication: specifies the authentication method used for OSPF packets. Options are
simple, password, and md5.
* Key ID: specifies the ID of the key for MD5 authentication. This parameter takes effect
only for MD5 authentication. The valid value range is 1-255.
* Key: specifies the authentication key used for OSPF packet exchange.
* Hello Interval: specifies the interval between Hello packets sent from the interface. The valid
value range is 1-65535.
* Dead Interval: specifies the timeout period of a neighbor. If the router does not receive any
Hello packet from a neighbor within this period, it considers the neighbor invalid. The valid
value range is 1-65535.
* Retransmit Interval: specifies the interval at which the router retransmits an SLA after the
LSA fails to get a response. The valid value range is 1-65535.
* Transmit Delay: specifies the delay time before LSA transmission. The valid value range is
1-65535.
• Redistribution
– Redistribution Type: specifies the type of redistributed routes. Options are connected, static,
and rip.
– Metric: specifies the metric of the redistributed route advertised by the router.
– Metric Type: specifies the type of external routes imported to the OSPF routing table.
* 1: indicates Type-1 external routes that are highly reliable. For OSPF, cost of a calculated
external route is equivalent to the cost of an intra-AS route and is comparable with the cost
of an OSPF route. That is, the cost of a Type-1 external route is the sum of the cost from
the local router to the corresponding autonomous system boundary router (ASBR) and the
cost from the ASBR to the destination address of the external route.
* 2: indicates Type-2 external routes that are less reliable. For OSPF, the cost of a route
from the ASBR to outside the AS is much larger than the cost of an intra-AS route to the
ASBR. Therefore, in OSPF route cost calculation, only the cost from the ASBR to outside
the AS is considered. That is, the cost of a Type-2 external route is equal to the cost from
the ASBR to the destination IP address of the external route.
– Route Map: This parameter is not configurable currently.
– Redistribution Advanced Options
* Always Redistribute Default Route: enables the router to advertise the redistributed default
route after startup.
