Scenario Operation Procedure
In above diagram, the OSPF Gateway is one gateway of the enterprise backbone (area
code is 0.0.0.0 and area subnet is 10.0.0.0/16) and it links with other OSPF gateways in
the backbone. It dominates two areas of subnets: area 1 with area code is 10.0.75.254
and area subnet is 10.0.75.0/24, and area 2 with area code is 10.0.76.254 and area
subnet is 10.0.76.0/24.
By operating with OSPF protocol, the OSPF gateway can gather the routing information
from other OSPF gateways in the enterprise backbone. And then it forwards the routing
information to the routers in its dominated areas.
Finally, the routers in the dominated areas of the OSPF Gateway know the shortest
routing path for each destination IP address of outgoing packets.
BGP Scenario
Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange
routing and reachability information between autonomous systems (AS) on the Internet. The
protocol is often classified as a path vector protocol but is sometimes also classed as a distance‐
vector routing protocol. The Border Gateway Protocol makes routing decisions based on paths,
network policies, or rule‐sets configured by a network administrator, and is involved in making
core routing decisions.
BGP may be used for routing within an AS. In this application it is referred to as Interior Border
Gateway Protocol, Internal BGP, or iBGP. In contrast, the Internet application of the protocol may
be referred to as Exterior Border Gateway Protocol, External BGP, or eBGP.
BGP Configuration
The "BGP Configuration" window allows you to check "Enable" box to activate the BGP dynamic
routing protocol and specify its self code.
BGP Neighbor List
Index skipping is used to reserve slots for new function insertion, when required.
