BGP Prefix Limit
- Configure eBGP session between ATE port-1 and DUT port-1,with an Accept-route all import-policy/export-policy under the neighbor AFI/SAFI.
- With maximum prefix limits of unlimited, and N.
- Advertise prefixes of
limit - 1
,limit
,limit + 1
. Validate session state meets expected value at ATE. - Ensure that DUT marks session as prefix-limit exceeded for limit+1 prefixes.
- Advertise prefixes of
- Advertise prefixes to exceed configured limit, and to
limit - 1
following session teardown, ensure session is re-established per the restart timer (with ATE session marked as passive). - With maximum-prefix warning-only configured, ensure that the routes that
were sent prior to the max-prefix being exceeded are retained in the routing
table by forwarding traffic to
prefix{0..n-1}
andprefix{n}
where n is the maximum prefix limit configured.
