Maintaining optimal BGP routing requires balancing fast network convergence with minimizing update overhead, a process often complicated by fixed Minimum Route Advertisement Interval (MRAI) settings. Prisma® Access now offers configurable BGP MRAI support, which provides a timer you can use to tailor routing convergence in your network.

MRAI acts to rate-limit updates on a per-destination basis. BGP routers wait for at least the configured MRAI time before sending an advertisement for the same prefix. A smaller number gives you faster convergence time but creates more advertisements, while a larger number decreases advertisements but can slow routing convergence. You can configure a flexible MRAI range with a customizable default value, allowing you to achieve the best balance between speed and network stability.
