Description

When configuring the queues for BGP route prioritization, the output-queue-priority statement allows you to specify the number of tokens that are available within each of the 17 BGP output priority queues. This allows you to balance the amount of work that can be done within the route prioritization queues.

When implementing BGP route prioritization, the output-queue-priority statement allows you to specify the priority at which a given BGP route or route type is serviced. BGP route prioritization can also be specified per BGP neighbor during BGP configuration, as well as for the sub-family types within the following address families:

  • evpn

  • inet

  • inet-mdt

  • inet-mvpn

  • inet-vpn

  • inet6

  • inet6-mvpn

  • inet6-vpn

  • iso-vpn

  • l2vpn

  • route-target

  • traffic-engineering

Default

By default, each of the 17 BGP route priority queues (or buckets) is assigned 1 work token so that misconfigured queues do not result in starvation.

When implementing BGP route prioritization, the following types of update messages are assigned to the lowest priority queue (1) by default: route refresh, topology change, and route withdraw.
