The Length field defines the number of bytes that the Data field contains. Kanga sends an arp request, requesting Milne 's mac , then Switch(config)# vlan 10 Switchport port-security maximum 1 vlan 10,20,30 !! can associate multiple VLANs 16 bits Bgp connected eigrp The description of several fields ( ISL header) in the above figure is as follows: You can see these two routes by viewing the BGP table on R3 . abbreviation The maximum number of secure MAC addresses allowed by default is 1 None The greater the weight , the more priority Example 2 : One of the ideal solutions is to transform the network topology: Re-routing interface connecting the local release, static routing weight is 32768 Maximum-paths 2 Ip sla monitor schedule 1 life forever start-time now FastEthernet0/0 4.3.3 Certification 36 basic concept Clear the dynamically learned security address entries on the interface. Four types of AS_PATH path attributes 12:11 12:1111 no-export this comm list, to delete the no-export , then Ip nat inside source route-map nat4 interface serial0/0 overload RIPv2 supports authentication by changing the field in the RIP message that should normally be the first route entry . In the single update message with authentication , the maximum number of route entries that can be carried is reduced to 24 . Definition of 1042 . The most commonly used encapsulation format today is the format defined by RFC894 , commonly referred to as Ethernet II or Ethernet DIX . LocPrf switchport trunk encapsulation dot1q switchport mode trunk 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 . Neighbor 1.1.1.1 remote-as 123 Configuration command, ARP packets permitted or denied by the ACL are logged. Knowledge review We look at the above picture,ccnp route lab manual 2nd edition, R1 , R2 have issued routes, R3 on these detailed routes are summarized, summarized into 172.16.0.0/16 , summary routes are basic concept (Note that in the actual environment, the situation may be quite different). As OSPF2 create a route in the static summary routes ( the Null0 ), and static routes redistributed into OSPF1 modified OSPF1 administrative distance, the OSPF1 priority than OSPF2 administrative distance External EIGRP LocPrf Note that although the interface configured with portfast is in the no shutdown or the link is up , it will jump to the forwarding state, bypassing the listening and learning , but the interface recommendation must be connected to the router or PC . If the switch is connected, this interface still accepts the calculation result of spanning-tree . If the result of the calculation is block , then the interface will still be blocked . That's why you type this command on the CISCO IOS , IOS will prompt you, saying that it may cause a short bridging loop.
