The TAG value is set when the originating ASBR generates an external LSA . If the external LSA is re-advertised to other OSPF autonomous systems, the TAG value is carried by default. Switchport port-security maximum 1 vlan 10,20,30 !! can associate multiple VLANs Convergence comparison between 802.1D and RSTP 10.1.13.3 There are class, classless routing protocol redistribute ------------------ 00:B0:64:04:09:99 Set metric xx Known via "ospf 1", distance 110, metric 20 Switch(config)# vlan dot1q tag native Lab 3 : The access layer switch is inserted into option82 , and the upstream core switch also turns on dhcp snooping. ? Path 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: Holddown timer expired In R2 , the energy from each R1 and R3 learning to 100.0 the EBGP route, if arranged on maximum-paths 2 Hostname R2 interface s0/0 If R1 starts auto-summary and introduces 10.1.1.0/24 in the way of re-distribution direct connection , the subnet will be automatically summarized to R2. Redistribution of class, classless routing protocols 46 doing what PS : In Ethernet, due to the conflict, two hosts on the shared medium send frames at the same time , which will cause conflicts. According to a specific algorithm, the minimum length of a frame in Ethernet is 64 bytes. 30.30.30.0/24 By using route tags in RIP , you can control the redistribution of related routes in other protocols. When republishing to other protocols, RIP routes simply compare the tokens assigned to them without comparing the entire route. As mentioned earlier, DAI performs ARP legality verification by means of the DHCP snooping binding database . Another basis for legality verification is the manually configured ARP ACL . The comparison principle of OE2 is first compared to the external metric of OE2 . If they are equal, further comparison of the internal metric is the metric to the ASBR . //Get out a summary route instead of the default route 192.168.1.0 the OSPF routing but will be re-injected into the RIP (because we deploy a two-way re-release), this is the route Feedback , the route was filling back. ? verification None Vlans allowed and active in management domain Peer using Route-map in the case of ) : 8 Ip prefix-list 1 permit 1.1.1.0/24 route-map test We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Path cost This property may not be supported, but even if it is not supported, the route containing the property should be accepted and passed Neighbor 10.1.23.3 remote-as 13 Before the DAI is deployed , if the ARP spoofing behavior occurs on the intranet ,ccnp switch questions 9tut, for example, the PC sends an invalid ARP packet, the switch cannot detect and defend the defensive action. No passive-interface fast 0/24 Trunking Y When R5 is updated to EBGP neighbor R2 BGP route 5.5.5.0 , NEXT_HOP =192.168.25.5 , this attribute will always be followed by this BGP route in AS234 . At this time, for R4 and R3 , I don't know how to go to 192.168. 25.5 , so the 5.5.5.0 route cannot be properly loaded into the routing table. One solution is to R2 in the IGP injection route 25.0 This external routes, the other is R2 its IBGP neighbors using the Next-Hop-Self , modify this prefix NEXT_HOP properties.
