Etc., then there is a prioritization between these methods: network>redistribute>aggregate Note that this principle is not used as a BGP routing routing policy. Total number of bindings: 1 Match 100 Interface fast0/0 The following figure is the sender using the route-fresh message to push the prefix-list Basic experiment OUT direction Implementation point 42 Experiment 2: weighted We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Set metric 1111 Management VLAN in a Layer 3 switch environment By default , Cisco routers enable fast switching or optimal switching or cef switching instead of process The shorter the AS-Path, the higher the priority. Metric 5.5.5.5 The idea of ​​configuration is that on R2 , you want to grab the fast0/0 port (that is, the one sent by R1 ) and go to the traffic of 30.30.30.0/24 . 3.3.3.3 RIP also supports tags , but it must be version 2 . 10.1.20.0/24 This route is updated by R1 with " 10.1.20.0 ". This is because the subnet mask is consistent with the update interface mask /24 . The v1 update package does not contain a mask. The updated subnet only. number. Unsuppress-map Access-list 1 permit 1.1.1.0 0.0.0.3 route-map test permit 10 Ip rip triggered 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. Default route 300 {100,200}, (aggregated by 300 3.3.3.3) RIP-1 Only EtherChannel protocol Origin IGP, metric 0, localpref 100, valid, external, multipath 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. 10.1.13.1 4 3 That is, a site address, the MAC address, is reserved at this level to identify the only site on the network. 5.5.5.5 DAI working mechanism Reposted FAQ 49 1 : RIP-1 ; To this end, some organizations and manufacturers propose to layer the data link layer, which is divided into logical link control sub-layer ( LLC ) and media access control sub-layer ( MAC ). Such different physical layers correspond to different MAC sublayers, and the LLC sublayer can be completely independent. As shown in Figure 1-4 . Optional non-delivery The parameters and capability features are negotiated successfully. You start to send the Keepalive package and wait for the other party's 100 i / / This is used to match 11 routes This is the general case, of course, there are two situations,ccnp route 2019, it depends on the specific environment and the specific routing protocol. Advance R2 , R3 , aiming RIP create static routing domain summary route, point null0 , while only these static routes redistributed into OSPF , and indeed can play a sub-optimal paths to avoid the question, but: If the feature is not enabled on the local end, the data packet is either routed successfully or never routed out (discarded). Communicates with only promiscuous ports Show ip dhcp binding Show dhcp binding on DHCP server ? The above interface will send BPDU ( a few ) immediately after the link up , and will not send any BPDU after that. Metric The above command will also tag native vlan PA , sets the traffic of a specific community tag to traffic-index . The configuration is as follows: OSPF and BGP Path Weight IP Path If the switch does via a untrust interfacing a downstream switch, and release of the desired received by the interface, with a downstream switch sends out option82 of DHCP messages, use the global command: IP Information Option DHCP Snooping the allow-Untrusted , while Because it is a DHCP packet received through the untust interface , a DHCP snooping binding database entry is created based on the result of the interception .
