Load balancing methods Knowledge review What is the cause of this phenomenon? R4 does not pass the route that R1 introduces and passes through R3 to R5 . Type Metric Port Mode Encapsulation Status Native vlan Fa0/20 on 802.1q trunking 1 Command description Hostname R5 Whenever a route is reflected by the reflector, the cluster -ID of the reflector (the cluster) is added to the route's Cluster-list attribute. UDLD mode of operation The maximum number of seconds allowed before the HOLDTime router must receive a keeplive or update message Host 192.168.1.111 255.255.255.0 Root modifies its own configuration BPDU to advertise the entire switching network about topology changes. Root sets the topology change ( TC flag) for a period of time in the configuration BPDU . This time is equal to the forwarding delay + Max. Age , the default is 35S. Router ospf 1 If the above into OSPF , is invalid, i.e., the static route is associated interface, in OSPF the network when the network routing number, and will not be declared into OSPF . Network If the access layer switch is connected to a single link,ccnp tshoot ticket 9, there is a single point failure of the single link failure. If any aggregation device is down, it will directly cause the downlink access network to hang. UDP The default bridge priority of the switch is increased to a higher value than the default ( 32768->49152 ) so that the switch does not become Root. Protocol overview Open loopback on R2 , IP is 172.16.10.0/24 , 172.16.11.0/24 The IP configuration is as above. The R2 interface is configured with two IP addresses, and both have announced that the entire network runs RIP . Basic VLAN communication principle C 10.1.12.0 is directly connected, Serial0/0 Commands 5.5.5.5 EBGP non-equivalent load balancing $ Passed between peers . If the route attribute of the route received between EBGP peers carries Local Preference , it will be triggered. After the summary command is added with the as-set keyword, the generated summary route can inherit some path attributes of the detailed route, thus avoiding some problems. The rules for inheriting detail attributes from as-set are as follows: Passive interface The Sticky Secure Address is a secure address that allows us to change the Port-Security interface to a "sticky" MAC address through dynamic learning so that it is not lost due to up/down of the interface . However, if we want the sticky security address entry to still exist after the device is rebooted , then we need wr . Write the configuration to the start-up config file. The Sticky Secure Address is also a great tool to simplify the operation of our administrators. After all, there is no need to manually tie them.
