On an RSTP network, if a port receives an RST BPDU and finds that its buffered RST BPDU is superior to the received RST BPDU, the port discards the received RST BPDU without responding.
During the initial formation of a spanning tree in STP, all STP switches consider themselves as the root bridge. Therefore, by default, they generate and send configuration BPDUs periodically (every______seconds). (Enter only digits.)
Similar to the OSPF DR, the IS-IS DIS needs to be elected on a broadcast network. However, the OSPF DR is preemptive by default, whereas the IS-IS DIS is not preemptive by default.
On an OSPF network, the I bit, M bit, and MS bit in the first DD packet sent by a router are all set to 1.
On an OSPF network, if a router receives an update of an LSA that exists in the local LSDB, the router updates the LSDB and floods the LSA.
The following figure shows the OSPF network of an enterprise and the OSPF configurations of R1. Which of the following statements is false about the network?
L2TP does not provide security encryption. Therefore, other security measures, such as IPsec, are required to ensure the security of the entire tunnel for data transmission.
On an enterprise network, the directly connected interfaces of two OSPF routers are on different network segments and have different masks. To establish an OSPF neighbor relationship between the two interfaces, you can change their network types to which of the following?
Huawei modular devices have multiple hardware modules that provide different functions. Match the following hardware modules with their functions.
Which of the following is the default interval at which the DIS on a broadcast IS_IS network sends CSNPs.
