* i Switchport access vlan 100 interface fast0/24 ... Neighbor 10.1.23.2 remote-as 200 On the debug information we found: Access-list 1 permit 192.168.2.0 LoopGuard Protocol Interface In CISCO IOS 12.2(33)SXH and subsequent versions, we can deploy port-security and 802.1X on the same interface. And before this software version: Reduce network migration time without disconnecting existing connections, and do not need to change device BGP configuration in large batches Network BGP neighbor : When two routers establish a TCP- based BGP connection with each other , they are called neighbors or peers. When the neighbors just establish a connection, they exchange all the candidate BGP routes, but after the initial route exchange, the incremental route update is usually sent only when the network information changes, and is not periodically updated. 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 ,ccnp tshoot quick reference guide pdf, 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 , 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.
