No-advertise Detailed rules Ip dhcp pool BIND Atomic character Switchport port-security mac-address sticky RC and RA are separated by RB . In this case, EBGP runs through a non- BGP router by using the configurable " multi-hop EBGP" feature . In other words, RB can not support BGP , and the configuration is as follows ( RA ) This type of data transmission service does not need to establish a connection, but it adds an acknowledgment mechanism to the transmission of data, which greatly increases the reliability. / / Kill 11.0 release all details except 11.0 AS_PATH , and AS_PATH only when routing out this AS or BGP routers to update EBGP will change when neighbors in AS inside will not change, therefore, in the AS internal, anti-ring requires the use of split horizon. So how to solve the problem that R5 ca n't learn routing? MAC address. Remove VLANs from the current list Show ip dhcp binding Show dhcp binding on DHCP server Ip dhcp relay information trust-all Reviser R5 sees the redundant path to the 100.0 network, the next hop is 3.3.3.3 , and finally R5 prefers R2 as going to 100.0 Configure a static default route locally, such as ip route 0.0.0.0 0.0.0.0 null0 Mechanism overview ! Route-map test permit 10 IBGP is synchronized with IGP The BGP update is carried by the TCP protocol. The port number used is 179. Because BGP requires TCP , there must be a BGP peer . 50min is an absolute time, the countdown starts after the configuration is completed,ccnp switch course, and the countdown is always performed regardless of whether the MAC is still active. Since the configuration of the first experiment Rl , therefore R2 Flights 13 segments, it is preferable that Rl , this time in R2 a clear click BGP neighbor Rl , and the Rl BGP connection DOWN , R2 Flights 13 routes and preferably the R3 , After R2 and R1 restore the BGP connection and receive the 13 route update of R1 again , R2 is still preferred to R3. Due to the inherent lag of network equipment, there is a propagation delay in the switching network. For the above reasons, topology changes can occur at different times and in different network segments in the switched network. If the Layer 2 interface switches directly from the block state of the spanning tree to the forwarding state, a temporary data loop may occur. To alleviate this problem, the port should wait for new topology information to propagate to the entire switching network before starting to forward the data frame.
