Can be configured in global mode or in interface mode, the difference is as follows: global configuration: spanning-tree portfast bpdufilter default A VLAN divided into several separate VLAN , the VLAN use the same IP network segment. Ip dhcp snooping verify mac-address The road selection has met our expectations. Access-list 2 permit 172.16.20.0 route-map BGP2OSPF permit 10 It means for VLAN100 traffic, not to log the ARP ACL discarded packets match Based on packet load balancing, all packets are rounded on the outgoing link. If you want to use message-based CEF load balancing, you need to configure this command on all outbound interfaces. The buddy experiment has verified that it can indeed be per-packet load balancing. If the local end has this feature enabled, the next-hop device does not support CDP ,ccnp switch syllabus pdf, then switch to the next next-hop . If there is no next-hop , skip the PBR. 100 When BGP routes are redistributed to the IGP , the iBGP routes are not redistributed by default . Only EBGP routes are re-advertised . bgp redistribute-internal is required to make the iBGP routes re-released. Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . We look R5 are BGP table: OR2 , SW1 , and SW2 run OSPF , and OR2 acts as the egress router of the telecommunications, injecting a default route into the OSPF domain. OR1 will be local B is passed to its IBGP neighbor C (doing a reflector), then on C , the route NEXT_HOP is still the A router (update source IP ) Command On the trunk port, as mentioned earlier, port-security can also be activated . The maximum number of secure addresses can be configured on the trunk interface, which can be based on interface configuration ( valid for all VLANs ) or VLAN- based . as follows: R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. BGP Deaggregation , also known as BGP splitting. Route summary We all know what the concept is. The advantage of route summarization is very obvious. It can reduce the entries of the routing table to optimize the network, but at the same time it also loses the accuracy of the route passed by the neighbor. For the detailed routing before the aggregation, we I don't know anything about it. Then split can be understood as a summary of the reverse action, when I receive a summary route, may be based on a purpose, I want to extract a specific detail route from the summary route, in order to strengthen the granularity of the route, of course The details are dependent on the summary route.
