100 i 1 i RIP redistribute directly connected If you do not set Metric , the default 1 -hop neighbor passed (the neighbors directly using this 1 jump as Metric ); redistributed static route default Metric = 1 , use the default-metric can modify this default value, this command No effect on the metric that re-releases the direct connector . Eliminate routing loops by horizontal splitting IP Routing Table 5 Match community 1 Configure no switchport ( routed port ) Layer 3 interface Network xxx mask yyy route-map zzz BGP is a classless routing protocol, a distance vector routing protocol, and automatic summarization is turned off by default (this depends on IOS ). Switch(config-if)# spanning-tree portfast [trunk] Switch(config-if)# switchport port-security aging type {absolute | inactivity} Finally note: Network 192.168.10.0 0.0.0.255 area 1 BGP anti-ring is implemented through AS_PATH , and AS_PATH is only changed after the route leaves the AS . Therefore , IBGP does not have EBGP anti-ring capability in the AS . To prevent loops, BGP routers will not be from IBGP neighbors. The learned route is advertised to other IBGP neighbors. Think of the route reflection cluster as a whole, then after C is passed to the RR , Of course, the subnet 172.16.0.0/16 can be further subnetted to get 172.16.10.0/30 or even 172.16.10.1/32 , then if these prefixes exist, when I am going to find 172.16.10.1 ,ccnp switch online questions, who's What is the highest match? Obviously, is the host prefix of 172.16.10.1/32 , or host routing? This is the longest match principle . A sends the BPDU out of its designated port, and the BPDU is flooded to the network. 100 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. Port number 521 Ip dhcp snooping verify mac-address Atom character example: Set default interface specifies how to send such a packet IGRP for OSI networks Metric for redistributed routes Mobile routes 200 i 32 bits COMMUNITY attribute is set . 4 th 8 value bit group, RFC1997 predetermined front 2B represents AS number, after 2B represents the basis for management purposes set identifier, the format of AA : NN , and CISCO default display format is NN : AA , may be used The global configuration command ip bgpcommunity new-format changes the CISCO default format to RFC format. Offset-list Acl number in/out offset value interface Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . R3 and R4 , R4 and R5 establish an IBGP neighbor relationship, and R3R4R5 uses LOOPBACK as the update source and refers to the neighbor . For example, if you go to a destination and there may be multiple equal-cost paths, you may actually use one of them when forwarding data. Use this command to see which interface is actually used for traffic forwarding. To do another test, PC1 privately modifies the IP address: ? Path After receiving the BPDU packet, the interface will immediately switch to the err-disable state. Ip community-list 30 permit 300:30 route-map PA permit 10 Through AS_PATH affect route choice 14 Document number Configure OSPF unicast updates: 32 bits ? Network Next Hop Metric LocPrf Weight Path If it is injected through the aggregate-address command, next-hop is equal to the update source IP of the summary router . These are all done by VTP pruning auto-negotiation. No auto-summary Note that the routes introduced outside the federation, the next-hop attribute will not change within the federation, even if it is passed between different member ASs , so R3 and R5 need to modify the next-hop attribute for R4 , set For your own update source IP , you already know how to do this? The greater the weight , the more priority ! s> 172.16.11.0/24 3 jumps. The LSA sends the neighbor to the neighbor, so the local route is filtered, and the neighbor has (because the neighbor has received the LSA ). Vlans allowed on trunk Can be detected when a violation time occurs, and can be punished The default load balancing method is round-robin Dhcp snooping binding database . as follows: Set tag 20 Switch(config-if)# spanning-tree [ vlan vlan-id ] cost cost Forward 1.1.1.1 BGP federation \ The basic configuration is as follows: Route-map xx permit 10 Bridge ID 30.30.30.0/24 The above configuration is only to solve the problem of data direction, but the problem of NAT : IP routing troubleshootingExperimental verification This route was therefore sent to R1 . Detect the reachability of the next hop, the default is off STP (PVST) Route summary issues to be aware of ? View and verify: federal Interface fast0/24 !! When the route matching ACL1 when Display all BGP routes advertised to a specific neighbor The configuration of SW1 is as follows: When the RR reflects the route from the client to the non-customer, it also appends its cluster ID to the CLUSTER_LIST , and if the CLUSTER_LIST is empty, it creates one. If the route reflector finds that its local cluster ID appears in the CLUSTER_LIST of the route it received , then it knows that a loop has occurred and ignores the route. The CLUSTER_LIST attribute is only used for RR anti-rings.
