Routers are networking devices that forward data packets between computer networks, routing packets from one router to another until reaching the destination node. There are several types of routers including core routers that forward packets within a network, edge routers that connect a network to external networks, and wireless routers that provide wireless network access in addition to routing. Routers work by receiving packets on one port and forwarding them to the appropriate outgoing port based on routing table information.

2. What is Router :
• Is a networking device that forwards data packets between computer networks .
• A data packet is typically forwarded from one router to another through the
networks that constitute the internetwork until it reaches its destination node.

3. Cont. :
• Routers are normally used to connect one LAN to another.
• Typically, when aWAN is set up, there will be at least two routers used.

4. Types of router :
• Core router
• Edge router
• Inter Provider Border Router
• Wireless router

5. Core Router :
• A core router is a router that forwards packets to computer hosts within a
network (but not between networks).

6. Edge Router :
• An edge router is a specialized router residing at the edge or boundary of a
network.
• This router ensures the connectivity of its network with external networks, a wide
area network or the Internet.

7. Inter Provider Border Router:
• Inter-provider Border router is used for Interconnecting ISP. It is a BGP
speaking router that maintains BGP sessions with other BGP speaking routers in
other providers' ASes. It support multi-routing protocols for secure data
processing and high performance.

8. BGP ?
• Border Gateway Protocol (BGP) is a standardized exterior gateway protocol
designed to exchange routing and reachability information among autonomous
systems (AS) on the Internet.

9. Wireless Router :
• A wireless router is a device that performs the functions of a router and also
includes the functions of a wireless access point. It is used to provide access to the
Internet or a private computer network.
