The secure address formed by the dynamically learned MAC is valid. If the MAC is in a failed state within 50 minutes (for example, the host is offline), the secure address is cleared after the aging time expires. Then, R3 deploys the two-way re-release, so the process 2 route is injected into process 1 , then the route of the A network segment will be injected back into process 1 , so that the priority of O is greater than OE , so R1 and R2 directly ignore this. Strip routing. Will not cause other effects. S0 192.168.12.1/24 r1 SW1(config)# interface vlan 10 FIG fancy, initial condition, C interface is elected non-designated port is Block , B sent from the designated port BPDU to C . Let us first consider the case of 802.1D . When the link between Root and B fails, since the interface connected to B on C is BLOCK , it does not send BPDU to B. Therefore, B considers itself to be Root at this moment , so it goes to C. Send yourself a BPDU for Root . Because at this time , the interface of C also stores the BPDU sent by B to the previous B , and this BPDU is compared with the BPDU sent by B to B.It is better, so C ignores these suboptimal BPDUs directly . Until the Max-Age timeout, the BPDUs sent by the previous B stored on the interface of C will be aged. At this time, the interface enters LST and starts to send BPDUs ,ccnp 300-101 ppt, indicating that the root is Root. . At this point, B accepts the facts and sets the interface that connects itself to C as the root port.
