QoS on routing protocol

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.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.


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

You can also propagate QoS via BGP.
Further reading:

BGP is using a TCP session (port 179 on one end) between the two routers for exchanging routing information.

For Juniper routers these packets are automatically (default configuration) QoS marked as "network control" and given priority in queuing - up to 5% of the link bandwidth.

I assume other vendors does something similar.
Yes, the same is true for Cisco:
25% maximum for "link queues (routing updates, keepalives, etc.), unclassified best-effort traffic (matched by class-default), or both"
