[123].[7-9] The above interface will send BPDU ( a few ) immediately after the link up , and will not send any BPDU after that. Both A and Root enter the Listening state on both ends of Link1 , and A will receive the BPDU sent by Root . Alternate port: Discard status. In addition to the root port and other ports to the root path, if the active root port fails, the replacement port becomes the root port, so the alternate port can be understood as an alternative to the root port. Configuring a VTP domain name The mechanism of proposal agreement is very fast, because they are not limited to any timers. This handshake mechanism will quickly spread to the entire switching network end and can quickly converge when the topology changes. Port-Security Recognized Range character example: The configuration commands are as follows: Gateway redundancy technology TYPE Requires trunk link support between switches For example, R1 redistributed into direct on the OSPF , with out distribution list can be filtered out direction 1.1.1.0 this external routes. But R1 redistributed incoming routing, if R2 with the out distribution lists direction tried to block R3 accepted routes or LSA , you can not, because this is not a local external routes originating. We can affect the routing by setting the LP value. For example, the same implementation allows R4 to access 100.0.1.0 and go to R3 , accessing 100.0.2.0. Neighbor 10.1.23.2 remote-as 200 neighbor 10.1.23.2 route-map test in Application 66 Summary 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. Locally find a route to the neighbor, and start preparing for TCP connection and monitoring remote peer In the past, switching was hardware-based forwarding, and routing was software-based forwarding, so the campus network used more switching networks. Path RR transmitting the AS ( Transit the AS ) is divided into small units, i.e. reflection clusters MAC sublayer 2.2.2.2 Maximum-paths 2 Number of existing VLANs 8 Tag 1111, type extern 2, forward metric 64 The next-hop attribute can be changed by next-hop-self Provide a better next hop address. If it is 0.0.0.0 , it means the way to publish this route. Router(config)# router ospf 1 If there are no dynamic and static routes on R2 , and the configuration is as follows: IP protocol number 89 Network Layer Reachable Information ( NLRI ) One or more (length, prefix) binary groups used to advertise IP address prefixes and prefix lengths SW3 receives this BPDU ,ccnp route final skills exam, but finds that this BPDU is less preferred than its own locally stored BPDU , so the BPDU is ignored. Routing Information Protocol Match ip address prefix-list 100 set extcommunity cost 1 10 (64513) 200 i 100 i FastEthernet0/0 Exit When track1 is true , that is, 10.1.1.2 is reachable, the data of the PC accessing the 100 network is lost to 10.1.1.2 . If track 1 is hung, the next next-hop is switched. The configuration of SW2 is as follows: The ARP packet of the element , then these messages correspond to an entry to save buffer usage. At the same time, only one system information will be generated. Dhcp snooping binding database . as follows: Address family Again, the following topology, the phenomenon is the same as above, pay attention to the summary route using the as-set keyword, the AS_PATH of the underlying detailed route will be put into {} , which is AS_SET . R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. Describe 100$|400$ Neighbor 3.3.3.3 update-source Loopback0 neighbor 5.5.5.5 remote-as 345 Local origin Weight Defaut-network takes precedence and becomes the default gateway gateway of last resort . However, if the network specified by ip defaut-network is learned from a dynamic routing protocol, ip route 0/0 takes precedence. Enhanced Interior Gateway Routing Protocol (EIGRP) Open Shortest Path First (OSPF) You can further configure this logical etherchannel interface. Set the interface to access mode Private-vlan ioslate A After receiving the response, you know B has established a connection with their locally. A also opens up an SAP value to indicate the connection, and sends a confirmation to B to establish the connection. Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . We look R5 are BGP table: Router(config-dhcp)#network [network address][subnet mask] Preferably , the routes sent by the EBGP neighbors (relative to the IBGP neighbors) are preferred to the EBGP routes in the EBGP and IBGP . Note that the first six rules in the BGP routing rules cannot be determined. Only in case of circumstances. Create a secondary VLAN : Penalty value: 1000 per swing Report routing information. Sw1(config-if-range)#no switchport // Configure the L3 interface Metric =0 The BGP AS is planned as follows: R1 , R2 , and R3 each have a network loopback route in the BGP process (without any policy); route summarization is performed on R4 and R5 respectively: 8 bits Note that the main TC while timer is timed on the port, and the BPDU sent by the port will be set by the TC bit , and the BPDU will also be sent out from the root port. Option 82 sub-option 1 is the circuit ID , which indicates the circuit identifier of the received DHCP request message. This identifier is meaningful only inside the relay agent node. The server side cannot parse its meaning, only as a meaningless one. Logo use. In general, the default is the access switch VlanID that receives the DHCP request packet and accesses the Layer 2 port name, such as Vlan2+Ethernet0/0/10 . The user can also specify its own proxy circuit ID . Usually sub-option 1 and sub-option 2 are used together to identify the information of the DHCP client.
