Port-security supports 802.1Q tunnel interface A valid entry in the database matches these ARP packets. Network 100.0.1.0 mask 255.255.255.0 Strange phenomenon: In the BGP table of R5 , there are only two routes advertised by R2 , and the 100.0 route from R3 is not passed to R5 via R4 . In other words, we expect that AS345 will have redundancy to 100.0 network. Remaining path (through R1 , [Experiment 5 ] There are subnet routes, the subnet route prefix length is different (but both match), and the longest match As shown above, the position of the line is 16+4=20 , so we get the summary address: 192.168.0.0/20 , which is the most accurate summary address.

Various types of ports of a Layer 3 switch Three-layer exchange The SYSID can also be used as an identifier for a VLAN or an MST instance. For example , the system ID extension of VLAN 100 is 100. / / Use this command to delete Set ip next-hop 11.1.1.2 exit Of course, the link type of the interface can be modified by commands. In interface mode: spanning-tree link-type ? Three-layer bundle ( 0xFFFF0000-0xFFFFFFFF ) is a reserved community value. In addition to these values, several well-known values ​​such as no-export , local-as, etc. are defined. For specific values, see RFC . So first on R1 and R2 , in order to allow them to reach the server 10.1.1.0 and 2.0 network segments, you need to configure two static routes: Origin IGP, metric 0, localpref 100, valid, internal Network Obviously, R2 is preferred to 10.1.12.1 . This is because the first 12 rules cannot be decided. Therefore, the neighbor IP is compared . Therefore, 10.1.12.1 is preferred . Of course, if the 10.12.1 address of R1 is changed to 10.11.12.1 , And on the R2 to do the corresponding modification of the neighbor ip , then R2 to 1.1.1.0 will switch to 10.2.12.1 , because this IP is small FastEthernet FastEthernet IEEE 802.3 Match x4 set Y Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only The configuration commands are as follows: Non- Route-map ( automatic ) mode : Redis static route-map test NEXT-HOP Typical configuration example: Access-list 1 permit 192.168.2.0 200 i Configuring BGP Federal Timer bgp 0 0 neighbor never goes down Lab 2 : The access switch is plugged into option82 and the core switch is relayed. In a route-map statement, if there is no match statement, match all When deploying the campus network, we often have the following special requirements for switches: Activate Port-Security (on the trunk interface) Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . The case of RSTP : Ip prefix-list 1 permit 1.1.1.0/24 route-map test Static Routing 4.3.3 Certification 36 The configuration of R2 is as follows: Preemption enabled, min delay 30 sec If there is a class route lookup ( no ip classless and ip cef is off ), when receiving a data packet, the router first searches for the main class to which the destination address belongs. If there is a main class route in the routing table, then the subnet is searched. If there is a subnet route, the query is limited to these subnets and further searched. If the final lookup fails (no subnet matches this route), the packet is dropped even if there is a default route; if there is no local For the main class route, see if there is a default route. If there is,ccnp switch download, then it will be forwarded by default route. If not, the packet will be discarded.
