Is used for routing between autonomous systems?
An Exterior Gateway Protocol (EGP) is a routing protocol that handles routing between Autonomous Systems (inter-AS routing).
What is autonomous system in OSPF?
For the OSPF protocol, an autonomous system (AS) is a collection of IP networks that are under a common administration, sharing a common routing strategy, and running only one routing protocol. OSPF supports multipath, which means it supports multiple routes to the same destination or system.
What protocol is used when communication is required between autonomous systems?
Border Gateway Protocol (BGP)
Border Gateway Protocol (BGP) refers to a gateway protocol that enables the internet to exchange routing information between autonomous systems (AS). As networks interact with each other, they need a way to communicate. This is accomplished through peering.
What does OSPF 1 and OSPF 2 mean?
In line router ospf 1 and router ospf 2 1 and 2 are Process ID which will be different for all routers. and Area 0 line 0 is the Area. If all routers have same area this means all these routers are controlled by same Admin or same Company. Loading…
How to configure OSPF routing using two routers?
Step 1:The first thing you have to do is to draw the topology Diagram using cisco packet tracer. Step 2: Assign IP Address on router Interfaces and PC. Now configure ospf Routing on Router R1 as i have done below. After you done ospf routing over router R1 it’s time to configure Router R2 for OSPF.
What are the RFCs for OSPF over demand circuit?
Not-so-stubby area (NSSA)—RFC 3101, which replaces and is backward compatible with RFC 1587. OSPF over demand circuit—RFC 1793. OSPF typically requires coordination among many internal routers: Area Border Routers (ABRs), which are routers connected to multiple areas, and Autonomous System Boundary Routers (ASBRs).
What’s the difference between OSPF stub area and NSSA?
A simple protocol such as RIP was usually run and handled the redistribution. With NSSA, you can extend OSPF to cover the remote connection by defining the area between the corporate router and the remote router as an NSSA. As with OSPF stub areas, NSSA areas cannot be injected with distributed routes via Type 5 LSAs.
