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.
