OSPF fast convergence is an extended feature to improve the speed of routing convergence. The working principle of PRC (Partial Route Calculation) is: when the network topology changes, only path calculation is performed on the affected nodes, thereby speeding up route computation.

As shown in the figure, in a medium-sized network, in order to improve the reliability of RR, BGP generally deploys double R.

When deploying dual EE, the Cluster IDs of the two RRs are generally set to be the same. What is the reason for this?

When troubleshooting the EBGP neighbor relationship, you find that the two directly connected devices use the loopback port to establish a connection, so execute display current-configuration configuration bgp to check the configuration of peer ebgp-max-hophop-count. Which of the following statements is correct?

According to this figure, what can we know? (Multiple choice)

Stream mirroring is divided into two modes: local stream mirroring and remote stream mirroring.
