Where is BGP on the OSI model?
OSI Transport Layer
BGP in networking is based on TCP/IP. It operates on the OSI Transport Layer (Layer 4) to control the Network Layer (Layer 3).
At which layer of the OSI model does DHCP operate?
DHCP runs at the application layer of the Transmission Control Protocol/IP (TCP/IP) stack to dynamically assign IP addresses to DHCP clients and to allocate TCP/IP configuration information to DHCP clients.
On which layer of OSI model IP protocols works?
Network Layer
TCP and UDP port numbers work at Layer 4, while IP addresses work at Layer 3, the Network Layer.
Is BGP a Layer 2?
“[2] BGP is an application layer protocol because it uses TCP to transport its messages, and RIP because it uses UDP for the same purposes. Other routing protocols such as OSPF are said to operate at the Internet layer because they encapsulate their messages directly into IP packets.”
What OSI layer is FTP?
Application
What is a Protocol?
| OSI Layer | Name | Common Protocols |
|---|---|---|
| 7 | Application | HTTP | FTP | SMTP | DNS | Telnet |
| 6 | Presentation | |
| 5 | Session | |
| 4 | Transport | TCP | SPX |
Which is the OSI model layer that BGP belongs to?
For example, both BGP and RIP perform routing which is usually considered as network layer functionality. BGP uses TCP while RIP uses UDP. So here protocols at the network layer which are using services from the protocols in the transport layer.
How are protocols classified on the OSI model?
The OSI model classification of protocols is not like a layer cake; in that you can’t say because this protocol relies on a layer 4 TCP or UDP, that it must therefore be higher on the OSI model than layer 4. Rather the protocols are classified by the services they provide. RIP and BGP provide layer 3 services.
Which is the underlying transport protocol for Rip?
BGP uses TCP as the underlying transport protocol and RIP uses UDP as the underlying transport protocol, however, it doesn’t mean that they are on Transport layer on the OSI model. Similar to SMTP (email), it is also on Application layer, however, it uses the underlying Transport layer (TCP/25). It supports all RIP, OSPF, EIGRP and BGP.
Which is the underlying transport protocol for BGP?
BGP uses TCP as the underlying transport protocol and RIP uses UDP as the underlying transport protocol, however, it doesn’t mean that they are on Transport layer on the OSI model. Similar to SMTP (email), it is also on Application layer, however, it uses the underlying Transport layer (TCP/25).
