Gratuitous ARP , the free ARP is a special ARP Request/response message, that is, the Sender IP is the same as the Target IP (usually used for IP collision detection). R2#sh ip bgp Weight For example, if you go to a destination and there may be multiple equal-cost paths,ccnp switch 5ch, you may actually use one of them when forwarding data. Use this command to see which interface is actually used for traffic forwarding. Next Hop 100 i Neighbor 10.1.12.1 capability orf prefix-list send neighbor 10.1.12.1 prefix-list FILTER in ? Other solutions, we will continue to introduce in the following experiments Port ID ( 2 bytes) = Port Priority (1 byte ) + Port ID (1 byte ) SW3#sh vtp status VTP Version capable VTP version running VTP Domain Name VTP Pruning Mode 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. Switch(config)# interface fast0/1 Switch(config-if)# switchport Switch(config-if)# switchport mode access When a spanning tree constructs a loop-free topology, it always uses the same four steps to determine: Show pvlan mapping Ip prefix-list 11 permit 11.11.11.0/24 route-map test permit 10 Timeout Configure abort timeout interval As we R3 on the RIP routes injected into OSPF marked the Tag 1111 , then the next Tags Solution: Use distribution lists to circumvent suboptimal path problems 101 Reviser The beginning of a string 10.1.25.2 Send TCP packet RIPV1 operational behavior 32 Neighbor 5.5.5.5 ebgp-multihop 3 Whether the MAC correspondence is legal or: There are 1.1.1.0 , 2.2.2.0 routes on R1 . Origin IGP, metric 0, localpref 100, valid, internal, best GLBP automatically manages the allocation of virtual MAC addresses and decides who is responsible for handling the forwarding work. These functions are performed by AVG ( active virtual The configuration of R2 is as follows: 15 / / This is used to match 11 routes Port switchport trunk encapsulation dot1q switchport mode trunk ! Interface fa1/0 or: A VLAN is generally a logical subnet composed of devices configured as members of this VLAN . LEN : Number of bytes in the Agent Information field , excluding the length of the code and len fields Bgp confederation identifier 345 bgp confederation peers 64512 neighbor 4.4.4.4 remote-as 64512 i Fa0/20 1,10 If the route learns to a non- client IBGP peer , it is reflected to all clients and EBGP neighbors. RIP is re-released into OSPF [123].[7-9] 100 / / Interface or protocol Distribute-list 62 OK , now go back to the main class network number 172.16.0.0/16 , then we will go out and look at the picture. 172.0.0.0/8 actually shifts the mask of this class B address to the left by 8 bits , so that the network number obtained is actually a large network number including 172.16.0.0/16 . Call it supernet . Ip route 1.1.1.0 255.255.255.0 serial 0/0 The Conditional inject is configured as follows (in BGP routing process mode): COMMUNITY attribute is set . 4 th 8 value bit group, RFC1997 predetermined front 2B represents AS number, after 2B represents the basis for management purposes set identifier, the format of AA : NN , and CISCO default display format is NN : AA , may be used The global configuration command ip bgpcommunity new-format changes the CISCO default format to RFC format. 0 100 0 100 i Redistribute static subnets Content Addressable Memory Table content addressable memory So match interface is a match with the outbound interface attribute, and this After Port-Security is activated on the interface , the interface has certain security functions, such as limiting the maximum number of MACs of the interface (connected) , thereby limiting the access host users; or limiting the specific MAC to which the interface is connected . Thereby achieving the restriction of accessing users. Then to perform filtering or limiting actions, you need to have a basis, which is based on the secure address – secure MAC address .
