Origin IGP, metric 0, localpref 100, valid, internal, best Originator: 1.1.1.1, Cluster list: 2.2.2.2 Assigning community 100:11 to route 11.11.11.0/24 on R1 and passing it to R2 , then R1 is configured as follows: Network An important improvement in RSTP is the rapid transition of ports. The traditional STP algorithm needs to go through several timers before transitioning an interface to the forwarding state. In order to get a fast convergence of the network, we may adjust the timer, but this method may affect the stability of the network. Address Resolution Protocol Rapid Transition to Forwarding State Neighbor 10.1.25.5 remote-as 345 no auto-summary Next Hop Double-point bidirectional routing re-release 91 Ip detects whether the IP address in the ARP body is invalid or unexpected, such as 0.0.0.0 , 255.255.255.255 , and multicast IP address,ccnp switch material, which are considered invalid IP . SenderIP verifies whether the message is an ARP request or response . And targetIP only if the message is the ARP response will be verified when Access-list 1 permit 1.1.1.0 Each update message describes only a single BGP route. This is because the BGP path attribute can only describe a single route. Viewed as one logical link STP port status Switch(config)# mls rate-limit layer2 port-security rate_in_pps [burst_size] Integrated pvst functionality and publicization Note that with route-map , the last is implicitly killing any , while the suppress-map is different. 100 i 16 bits There are 2 forwarders (1 active) So in fact, it is very simple, as long as the prefix and mask part of the route, respectively, use the source and destination parts of the ACL to match. When a data frame is sent from a trunk port, the frame is sent directly. By default, the longest matching principle is adopted. If it matches, it will be forwarded. If there is no match, the default route will be found. If the default route is not available, it will be discarded. The BGP update package is as follows. You can note that the length of the AS is 2 , which is " 300 , 100 ". Note that this is an ordered list of ASs . Vlans allowed and active in management domain IP Address 192.168.1.0 declares that it has entered RIP , and R3 and R4 can learn this route and load it into its own global routing table. Then if we are at Configure the aging time of the security address. An escape character that is used to convert the control character immediately following it to a normal character In summary, for IBGP to work properly, you must implement one of the following configuration options: Sourced in sev-epoch 1 Encap length 14 Set default interface specifies how to send such a packet Summary 29 BPDUFilter Local origin Verify set ip default next-hop technical background Set ip next-hop verify-availability based on object tracking To other neighbors The adjacency list in the CEF component is used for MAC or Layer 2 rewrite information. 100 Set the interface to DTP dynamic negotiation, optional auto or desirable Origin IGP, metric 0, localpref 100, valid, external, multipath Ip prefix-list 1 deny 11.11.11.0/24 route-map test permit 10 Set interface specifies how to send such a packet set ip default next-hop specifies the next hop to be forwarded set ip next-hop specifies the next hop to forward The figure above is the initial state. Revision date The Layer 2 switch searches for VLAN configuration information based on the destination MAC address and VLAN ID of the frame, and determines from which port the frame is sent out. Due to the lack of a feedback mechanism, the interface connecting A to Root from Listening to Forwarding needs to experience a delay of 15*2s . In this case A , B , C the second line on the user traffic problems (since D in better received BPDU after the P1 port block , this time ABC corresponds A root port transitions to the forwarding are in the network before the " buffer zones " ) DHCP is very familiar. For the DHCP client, the initial process is to find DHCP by sending a broadcast DHCP discovery message. Router(config)# ip prefix-list {list-name [ seq number] { deny | permit } network/length [ ge ge-value ] [ le VLAN10 , then the SVI interface corresponding to VLAN10 is interface vlan10 or SVI10 . This SVI10 is a Layer 3 interface. You can configure an IP address for this SVI port , which is the same network segment as the IP address of the PC user in VLAN 10 . , VLAN10 users in the gateway will be able to point to this SVI interfaces, when VLAN10 the PC network required to access the network segment outside their data to the gateway, which is SVI10 , and then by the SVI to do routing and data forwarding lookup. In fact, in this understanding process, we can route the model to the analogy with one arm.
