Hi,<br />
<br />
You do not set QoS 'on' a routing protocol, but you can use QoS to ensure sufficient bandwidth for routing. <br />

You can also propagate QoS via BGP.<br />

BGP is using a TCP session (port 179 on one end) between the two routers for exchanging routing information.<br />
<br />
For Juniper routers these packets are automatically (default configuration) QoS marked as &quot;network control&quot; and given priority in queuing - up to 5% of the link bandwidth.<br />
<br />
I assume other vendors does something similar.

Is the QoS also set for routing protocols, like BGP. Please let me, I thought that protocols like BGP were more of control protocols and did not need QoS settings. Please shine some light.

QoS on routing protocol

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.

Internet Protocols

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
