Dynamic Routing
The
NAT (Network Address Translation) feature transforms a private IP into a public IP, allowing
multiple users to access the internet through a single IP account, sharing the single IP address. NAT
break the originally envisioned model of IP end-to-end connectivity across the internet so NAT can
cause problems where IPSec/ PPTP encryption is applied or some application layer protocols such
as SIP phones are located behind a NAT. And NAT makes it difficult for systems behind a NAT to
accept incoming communications.
Open Shortest Path First (OSPF)
OSPF:
Enable to activate OSPF routing.
Rule Index:
The numeric route indicator. The maximum entry is up to 10, ranging from 1 to 10.
Interface:
Set the interface which runs the OSPF process (involved in OSPF routing). It can be
WAN interfaces or established GRE tunnels.
Area ID:
The OSPF area identifier.
It is a decimal number in the range of 0-4294967295. Enter the
area ID in which the interface belongs to. The area with area-id=”0” is the backbone area.
If the router has networks in more than one area, then an area with area-id=”0” (the backbone) must
always be present. All other areas are connected to it. The backbone is responsible for distributing
routing information between non-backbone areas. The backbone must be contiguous, i.e. there must
be no disconnected segments. However, area border routers do not need to be physically connected
to the backbone - connection to it may be simulated using a virtual link.
