You can enable the OSPF routing function by checking “Enable” checkbox for the
OSPF item and filling the “Backbone Subnet”. You can add up to 8 area subnets
for the OSPF network and enable them individually. But also you can modify
some existed OSPF areas by clicking corresponding “Edit” command buttons at
the end of each OSPF area definition in the OSPF Area List. Besides,
unnecessary OSPF areas can be removed by checking the “Select” box for those
areas and then clicking on the “Delete” command button at the OSPF Area List
caption. When you finished setting, click on “Save” to store your settings.
3. BGP: Border Gateway Protocol (BGP) is the protocol backing the core routing
decisions on the Internet. It maintains a table of IP networks or 'prefixes' which
designate network reach-ability among autonomous systems (AS). It is described
as a path vector protocol. BGP does not use traditional Interior Gateway Protocol
(IGP) metrics, but makes routing decisions based on path, network policies and/or
rule-sets. For this reason, it is more appropriately termed a reach-ability protocol
rather than routing protocol.
