the default cost assigned to a Fast Ethernet interface is 10. This means that OSPF will consider a Fast Ethernet link with a cost of 10 as the reference point for calculating the cost of other routes. Any link with a higher bandwidth will have a lower cost in OSPF, ...
If the neighbor changes from a lower status to a higher status, this trap message is informational only, and no action is required. If the neighbor changes from a higher status to a lower status, services may be interrupted. Possible Causes 1. The status of the interface of the virtual ...
As defined in OSPF, LSAs can be flooded to a link only when the neighbor status reaches Exchange or a higher state. When the status of the interface on the primary link is lower than Exchange, OSPF reselects a primary link from concurrent links for flooding LSAs. After receiving LSAs flood...
The cost command is used to override the auto-costing calculated default value for interfaces. Using this formula, the default path cost is 1 for any interface that has a link bandwidth of 100 Mbps or higher. If this value does not suit the network, config...
This authentication type applies to the entire router process unless overridden by a lower hierarchical level such as the area or interface. Step 5 message-digest-key key-id md5 { key | clear key | encrypted key | LINE } Example: RP/0/RP0/CPU0:router(config-ospf)#...
The cost of interfaces with link speeds lower than 100Gbps is higher. To avoid routing loops, set the bandwidth to a consistent value across all OSPF routers. The following example commands configure the auto-cost reference bandwidth for 90Gbps link speed: cumulus@switch:~$ sudo vtys...
When you set the auto-cost reference bandwidth, Cumulus Linux dynamically calculates the OSPF interface cost to support higher speed links. The default value is 100000 for 100Gbps link speed. The cost of interfaces with link speeds lower than 100Gbps is higher. To avoid routing loops...
The method for configuring cost values differs between the OSPF and RIP protocols. Configure the cost values of OSPF links to ensure that preferred routes to destinations have a lower cost than less preferable routes. The less preferable routes, with the higher cost, are not used except upon fa...
Where it would make a difference is if Area 2 had a high cost path within it's area and a lower cost path outside, it would always chose the intra-area one, irrespective of that higher cost. In rfc1583 it's based on cost. In this respect I think that the command works under IOS...
