? For 802.1D , when a port is elected as the designated interface, which from blocking to forwarding at least 30S of time. However, in RSTP , the proposal/Agreement mechanism enables the interface to complete a fast, reliable transition in seconds. Route-refresh Then, the situation is different for RSTP . After receiving the sub-optimal BPDU , C will immediately send back its own BPDU , so that B can understand the topology. This mechanism is very similar to BackboneFast . Basic 28 ? 100 i Note 21 To configure globally, use the command: SW3(config)# spanning-tree portfast bpduguard default ,ccnp switch 300-115 pdf 2017, which activates bpduguard on all interfaces that activate the portfast feature : DAI configuration example R1(config-router)#redistribute rip subnets tag ? If R1 turns on auto-summary and network 1.0.0.0 mask 255.0.0.0 , it is advertised to R2 summary route 1.0.0.0/8 Y ? Neighbor 10.1.23.3 remote-as 300 BGP does not update the route periodically. It is updated only when needed. Because the route of the public network may be turbulent, there will be a certain waiting time for triggering the update. The IBGP peer is 5S . The EBGP peer is 30S . During the time, BGP can still collect routing information, so BGP convergence will be slower. : 1 to 3 Reduce network migration time without disconnecting existing connections, and do not need to change device BGP configuration in large batches / / This is used to delete the no-export attribute, is a list of commands *>i ^a.$ The switch receives the DHCP request , which inserts option82 information into the message (of course, you must do the corresponding configuration first). In the inserted information, the remote-ID suboption is the MAC of the switch ; the circuit-ID suboption is received. The interface ID to the DHCP request message . The packet contains a maximum of 25 routing entries. Distribute-list route-map test in ! The configuration of R1 is as follows: What happens to the two-way re-release of RIP to OSPF on R3 ? We assume that the configuration completed on R3 , the route 192.168.1.0 will be injected into OSPF by R3 , and will be updated to R1 , and then updated by R2 to R4 . At this moment, R4 learns this from both OSPF and RIP . Routing, what would it do? Of course, OSPF is preferred because AD is small, so in its routing table, the route about 192.168.1.
