100 i TRUNK Delete a specific community value in the community list Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only ADJ-RIBs-IN stores unprocessed messages from peers. The included routes are all available routes The switch forwards the DHCP packets carrying the Option 82 information to the DHCP server. Routing entry for 192.168.1.0/24 Advertised to update-groups: 1 The composition of regular expressions Community Lead ( PreambIe ) Neighbor 10.1.23.3 remote-as 13 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 . 5.5.5.5 2 : Reponse message, send all or part of its routing information, in a Response message Untitled-1 *>i s> 172.16.10.0/24 Any Preferred routes sent by EBGP neighbors (relative to IBGP neighbors), preferred federation EBGP in federated EBGP and IBGP 2 : Reponse message, send all or part of its routing information, a Response When ISP1 fails, GW senses through tracking , so the data is switched to ISP2. basic configuration 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 Router bgp 100 Switch(config-if)# spanning-tree [ vlan vlan-id ] port-priority pri Sw(config)#vlan 201 Basic VLAN concept ... We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows When a data frame is sent from a trunk port, the frame is sent directly. Configure Port Security Rate Limiter *> 100.0.1.0/24 In the above example, the phenomenon we mentioned, R4 will know the route from OSPF and RIP to 192.168.1.0/24 , and finally R4 will choose OSPF route. This is a phenomenon we don't want to see in this environment, because it creates a sub-optimal path. The AD values ​​for several common routing protocols are listed below: We know that the AD value of a static route is 1. The above configuration method actually changes the AD value of the static route to 10 . In this way, we have two default routes, one for the telecom exit, the AD value is the default 1 ; the other points to the education network exit, and the AD value is 10 . Then after Management VLAN in a Layer 3 switch environment Load balancing: round-robin Group members: A advertises the detailed route to B , B advertises the detailed route to C and D , and C advertises the summary route. At this time, the summary route will be transmitted to B in addition to being notified to D , and this may cause problems. Therefore, you need to filter the summary route on the IP distribution-list x of neighbor B on C. Otherwise, a routing loop will occur. If the aggregate-address does not contain any keywords, the details are also passed, and the summary route is also passed. Network BGP routing table entry for 100.100.100.0/24, version 3 Paths: (2 available, best #1,ccnp 300-115 exam cost, table Default-IP-Routing-Table) Multipath: eBGP The DA 40bit multicast address is used to indicate that this FRAME is an ISL . 1 R2 The above configuration is only to solve the problem of data direction, but the problem of NAT : Not advertised to any peer Local In the above figure, the configuration revision number of server and client is the same, but the vlan information is different. At this time, an error will be reported, prompting md5 digest checksum mismatch Next Hop R3 receives two routes, respectively carrying the community attribute as above. Now, we only want to delete the no-export attribute of the 11 route . Route-refresh SwitchA hangs The secure address entry can be configured by using the MAC ( SecureDynamic ) dynamically learned by the port , or by manually configuring the interface ( SecureConfigured ) and the sticy MAC address ( SecureSticky ). Match ip address 2 set metric 3 Switch(config)# spanning-tree vlan vlan-id priority pri In Ethernet, different media access methods are provided for different duplex modes: Route-map LP permit 20 match ip address pref 2 set local-preference 100 Configured MAC Addresses : 0 !! Manually configured secure MAC address, not here 3.3.3.3 (metric 65) from 3.3.3.3 (3.3.3.3) Static The routing between the internal LOOPBACK of the AS can be learned separately. Both R1 and R3 update the route of the 100 network segment to R2 . Without any policy, the BGP routing rule will always be compared to the RID , and finally the route of R1 is preferred . 192.1.168.3 3 0003.44d6.c52f 2BB648EB interface-id 1bdb223f IP address, and then take the destination IP address to look up in its own routing table. After finding the "best match" entry, the packet is forwarded according to the outbound interface or next hop IP indicated by the routing entry . This is the IP route. ( IP routing ) . And each router maintains a routing table locally. The MAC sublayer is responsible for the following tasks: 0 100 0 100 i ( Optional transitive ) So to rule 12 : if multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred . The MAC address is burned in the ROM of the Network Interface Controller (NIC ) . LocPrf 100 100 i LocPrf *>i100.0.2.0/24 Commands Example of multiplication characters: As mentioned above, the secure address entry formed by the dynamically learned MAC address of the interface will lose the secure address entries formed by the dynamically learned MAC after the interface is up/down , but all interfaces are used. The switchport port-security mac-address is manually configured and the workload is too large. Therefore, this sticky mac address allows us to turn these dynamically learned MACs into a "sticky state " . It can be simply understood that I will learn dynamically, and after I learn, I will glue you up to form a "static". "(Effectively SecureSticky ) entries.
