Lowest sender bridge ID 802.3 does not recognize the upper layer protocol and must be used with a dedicated LAN ( such as IPX) . Route accurate summary algorithm When UDLD detects a unidirectional link failure, it administratively shuts down the interface and prompts the user. Unidirectional links can cause various problems,ccnp switch route tshoot, including spanning-tree topology loops Violation Mode : Shutdown !! After the violation, the default is shutdown Aging Time : 0 mins Neighbor 5.5.5.5 remote-as 345 ? Both SW1 and SW2 can learn, and three-year-olds can do it. What is an invalid arp entry: Enhanced Interior Gateway Routing Protocol (EIGRP) Open Shortest Path First (OSPF) Rl , R2 , R3 using LOOPBACK neighbor relationship with the address of 1.1.1.1 , 2.2.2.2 , 3.3.3.3 , running OSPF such Switch, the switch also forwards it with an updated message to all attached LANs for which it is the designated switch. 201 200 Next Hop Two-point bidirectional routing re-release implementation 98 Route-map test permit 10 set community ? BGP Identifer ROUTER-ID and OSPF selected routerID consistent manner 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. 10.1.12.2 Describe Several problems with VTP Cause: After the ARP Request is sent , the ARP Reply is prepared for a large number of reasons: scanning on the same network segment (host), scanning across network segments (network device) Offset-list 1 out 10000 fastEthernet 1/0 UDP Weight As mentioned above, a route is allowed to carry multiple community values ​​to form a community list. If you want to delete one or several community values, for example, SW2 and SW3 are similar situations; note that at this point we are not allowed to do any static configuration of the allowed vlan configuration on the trunk port. Virtual-Template Virtual Template interface Virtual-TokenRing Virtual TokenRing The longest match principle is the default route lookup method for CISCO IOS routers. When the router receives an IP packet, it performs bit-bit bit-by -bit lookup between the destination IP address of the packet and the entry in its local routing table until the longest matching entry is found. This is called the longest match. in principle. RIP V1 supports a maximum of 6 and defaults to 4 equivalent load balancing. And does not support verification. V2 supports verification. Switchport access vlan 10 interface fast0/24 When a BGP route is sent from the group members of the cluster to the RR , RR Burst interval , the default is 1s , optional configuration. This is a continuous detection period, used to detect the number of ARP packets in this time period . The default is 1S , so that is, within 1S , if 15 (default) ARP is exceeded , the violation is. This time can be selected from 1-15S. Each group of GLBPs can have up to four member routers as ip default gateways. These gateways are called AVF ( active virtual forwarder ). * Switch(config-vlan)# name Classroom If the ibgp keyword is not associated , only EBGP routes will be equivalently load balanced (by default only for EBGP routes). If maximum-paths is not configured , the next routing principle will be followed. Think carefully about what will be wrong, in fact access-list 1 deny 172.16.32.0 is a summary route 172.16. 32.0/21 SwitchB first detects the topology change, and then generates the TCN BPDU and sends it out from the root port (because the root port is in the direction of the root bridge), B will continuously send the TCN BPDU until the designated switch C sends a TCN ACK to confirm. Dhcp-bindings none —Does not log packets that match DHCP bindings. How to perform non-equivalent load balancing? In this figure, the bandwidth of the uplink interface of R2 is actually not equal. / / There is a S entry in the routing table Y STP requires network devices to exchange messages to detect bridged loops. This message is called the bridge protocol data unit BPDU. The blocked port also receives BPDUs continuously to ensure that a new STP can still be calculated when the fault occurs . To understand the working process of STP , it is very important to understand the meaning of the fields in the BPDU , because these are the root of the work STP relies on.
