Encapsulate the ISL header and the new FCS on the basis of the original data frame Unicast Update Metric The packet contains a maximum of 25 routing entries. No auto-summary BGP routing table entry for 1.1.1.0/24, version 2 R2 becomes the demarcation point between RIP and OSPF domains. So how can I let R1 learn the route from OSPF and let R3 learn from RIP?

Port security removes all addresses learned on VLANs other than the native VLAN.

This summary route was generated by R3 and passed to R4 . At this time, the AS_PATH of this summary route is 300 , and the detailed route under it is lost.

Then call the track object in the route-map 100 This mode is the most worthy of reference . It is based entirely on other switching modes. The focus is on billing, monitoring, and network management of packets flowing through . The security address entry thus formed (which is SecureSticky ) will not be lost even if the interface is flipped. If wr saves the configuration and the command is written to config.text , the security address will not be lost even if the device is restarted. Switch(config)# vlan 20 Technical analysis: If you turn on always-compare-med Manual summary The default violation is shutdown .

AS65102 as a transit region ( trasit AS ), the AS inside BCDE running the OSPF , such that AS within reachable; D and C did not run Under normal circumstances, the data is preferred to go ip next-hop , that is, go ISP2 Router(config)#router rip Configure the primary VLAN to associate the Layer 2 secondary VLAN to the primary VLAN. When we set the number of MAC addresses allowed on the interface to 1 and set a secure address for the interface, then this interface will only be for that MAC. Of course, it is ok to filter the prefix list in the in direction on R2 . Select the port for the Channel For the same BGP connection, the passwords must be the same; different neighbors can set different passwords. After the authentication is configured, all data segments transmitted through the TCP connection between the peers are verified. 5.5.5.5 *>i Neighbor 5.5.5.5 remote-as 345 The message contains: Network, which is consistent with topology expectations, but the underlying cause is still due to the learning of R2 compared to IBGP routes from R3 . No synchronization no auto-summary GLBP Select 10.1.25.2 as the next hop to the two network segments and load the route into the routing table. So why does R5 choose R2 ? Note that the BGP created by R3 uses the AS number of 64512 , which is the federate member AS number instead of the federated AS number. In an Ethernet environment, nodes communicate with each other and need to know each other's MAC address. The configuration of R1 is as follows: The next hop (the Next Hop) - if present , it identifies a better than advertised router address of the next hop address. In other words , the next hop address it noted , that in the same measure than - advertised subnet router closer to the destination. If this field is set to all 0s (0.0.0.0), the address of the advertising router is the optimal next hop address. 1.1.1.1 (metric 129) from 4.4.4.4 (4.4.4.4) Neighbor 10.1.23.3 remote-as 300 SW1(config-if)# switchport nonegotiate Bgp bestpath as-path ignore The above network is equivalent to network 1.0.0.0 ( network has a class declaration) // match AS ( 100,1 ) and ( 200,1 ) The figure above is the initial state. When BGP routes are redistributed to the IGP , the iBGP routes are not redistributed by default . Only EBGP routes are re-advertised . bgp redistribute-internal is required to make the iBGP routes re-released. BGP has three management distances, 200 learned from IBGP and 20 learned from EBGP . This is because the design concept of BGP works. Establish BGP neighbor relations GLBP After the Port-Security feature of an interface is activated, the default maximum number of secure addresses is 1 , that is, the interface uses its dynamically learned MAC address as a secure address without manually configuring a secure address. This interface is equivalent to being exclusive to the MAC (the device to which it belongs). And the default violation is shutdown Experiment 1: host-dependent Know (configuration is only done on the RR ). Note that the RR only advertises or reflects the best path it knows. Neighbor 4.4.4.4 next-hop-self The destination IP address of the route , which can be the address of the natural network segment or the subnet address or Local-as Match community 1 When a data frame is sent from the Access port, the switch strips the VLAN tag of the frame and then sends it out. BGP can use the route tag in the OSPF packet to carry the AS_PATH information when it traverses OSPF . In fact, CISCO 's BGP automatically completes the process (note that only the AS_PATH attribute is automatically entered into the OSPF TAG field ).

Other IP routing protocols do not support this feature. length Note that the above is the default metric when re-publishing from other dynamic routing protocols into this routing protocol . If you republish a local direct connection or a static route, the situation changes, as follows: GLBP The cost of the route. !

The secondary VLAN is mapped to the SVI interface of the primary VLAN , allowing for Layer 3 switching of pVLAN ingress traffic. Match ip address prefix-list 11 set as-path prepend 600 On the debug information we found: Network xxx mask yyy route-map zzz PVST+ If RP2 matching route exists in the BGP table, RP2 is advertised ; if RP2 hangs, RP1 is advertised.

Set tag 10 Origin IGP, metric 0, localpref 100, valid, internal, best BGP Solution: Use distribution lists to avoid the sub-optimal routing problem 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. 20 1,10,20,30 !! In the case of turning off VTP prunnig , trunk defaults to traffic for all VLANs , which is in SW2 The TAG field ( 32bits ) is only present in the external LSA . 3.3.3.3 Frame check sequence FCS 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. Detailed rules The DAI is deployed on the switch to ensure that legitimate ARP requests or responses are released and illegal ARP messages are discarded. The main actions of the switch after deploying DAI are as follows: Finally , select a designated port DP on each segment , sw1 is the root bridge, all interfaces are DP , and finally compare the two interfaces of the direct link between SW2 and SW3 . SW2 receives from the interface SW3 sent BPDU , SW3 also receive SW2 sent BPDU each compare your received BPDU in the bridge ID (also called the comparison transmission bridge ID ), the final SW2 since the MAC address Smaller wins.
