??? aggregate ipv4-address { mask/masklength }[as-set lattribute-policy route-policy-namel ldetailsuppressedlorigin- policy routein policy-name2[suppress3policy route-policy-name3], multiple parameters can be used to influence summary routes and their results. The correct description about the command is ?( Multiple choice questions).

If As-set is configured, the A S_PATH of the aggregate route contains ass path information for all specific routes in case the route loop is blocked

If As-set is configured, the A S_PATH of the aggregate route contains ass path information for all specific routes in case the route loop is blocked

If Suppress-policy is configured, aggregate routes are also generated, and the if-match clause in Route-policy is used to pick suppressed detail routes. Detail routes that match Route-policy are still advertised to other BGP neighbors

If Origin-policy is configured, only detail routes that match Route-policy can participate in aggregation

If You configure The Interface-policy, you can change the properties of the aggregate route

Although the STP protocol can solve the loop problem, it affects the quality of user communication due to the slow convergence of the network topology. RSTP has made many improvements to STP, which of the following is not an improvement of RSTP to STP?

If a port does not receive a configuration BPDU sent by the upstream device for 4 consecutive Hello Time, the device considers the negotiation with this neighbor to fail

In addition to the 3 port states, RSTP vice adds 2 new port roles

Non-root switches running RSTP send configuration BPDUs at intervals specified by Hello Timer, a behavior that is entirely autonomous for each device

RSTP port state specification is divided according to whether the port forwards user traffic and learns the MAC address, reducing the original 5 port states to 3

If a port does not receive a configuration BPDU sent by the upstream device for 4 consecutive Hello Time, the device considers the negotiation with this neighbor to fail
