Atomic_Aggregate and aggregator On the trunk port, as mentioned earlier, port-security can also be activated . The maximum number of secure addresses can be configured on the trunk interface, which can be based on interface configuration ( valid for all VLANs ) or VLAN- based . as follows: (empty), in other words, the MED will not be transmitted out of this AS Routing Feedback (feedback) is a re-release in the deployment of routing requires a great attention to the phenomenon. As shown above, R5 will 13 We will ping 1.1.1.2 repeat 1 size 1500 , we will find that R1 directly sends an ICMP packet, no fragmentation, the message is as follows: Then all the 172 network segments on R1 and R2 are suppressed. At the same time, since the route-map test only matches the 1.0 and 2.0 network segments (in AS100 ), this summary route, AS_PATH only inherits AS100 , which is 300 100 ; The smaller the MED, the higher the priority The longest match Aging Type : Absolute SecureStatic Address Aging : Disabled Implementation point 42 100 ? Experimental needs All devices in a VLAN are in the same broadcast domain, and different VLANs are different broadcast domains. Fa0/20 Between ASs , and within AS , BGP hopes that the IGP protocol can be handled by itself, so the administrative distance of IBGP routes is set to a large AD value of 200 . What is an invalid arp entry: Redundant RR environment R4#show ip bgp 172.16.0.0 The configuration of R2 is as follows: No synchronization no auto-summary 200 i Configure this command. When routing, the router only compares all routing entries with the AS_CONFED_SEQ attribute. This command is used for federated routers, while weight and LP have higher priority than MED. One point and one asterisk, match all, any DAI working mechanism Ip prefix-list ABC seq 5 permit 0.0.0.0/0 le 32 Integrated pvst functionality and publicization The VTP protocol sends a VTP advertisement on the trunk link through the multicast address 0100-0CCC-CCCC . At the same time, the two routes are marked in the BGP table: " *> ", indicating that the two routes are valid , and the best or optimal, best , so they will be passed to the IBGP neighbor of R3 . That is R4 Dhcp-bindings all —Logs all packets that match DHCP bindings. Use a static route to the next hop Neighbor 5.5.5.5 update-source Loopback0 Encapsulate the ISL header and the new FCS on the basis of the original data frame If multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred . Network 100.0.2.0 mask 255.255.255.0 If there is no tag , mark the PVID of the Access port and proceed to the next step. 100 Origin IGP, metric 0, localpref 100, valid, external, multipath, best Ip default-network 172.16.3.0 8 bits Switch(config)# vtp mode {server | client | transparent} Establish BGP neighbors ORIGINATOR_ID is a 32-bit value created by a route reflector . This value is the IBGP routerID of the route initiator in the local AS . Note that this initiator is not necessarily the initiator of this route (there is experimental verification below), if the initiator finds its RID In the received route / / used to define the condition prefix to be injected Clear ip bgp soft in // Inbound soft reset, locally send route-refresh to all BGP neighbors or: 3.3.3.3 If there is no tag , mark the PVID of the trunk port and proceed to the next step. Maximum MAC Addresses : 1 !! The maximum number of secure addresses, the default is 1 We found that both routes are best and are loaded into the routing table. At the same time, the same OSPF route is learned from both processes and is used on a first come, first served basis. Therefore, if R3 first learns the route from R1 , it will naturally ignore the one that R2 re-releases. However, if the neighbor relationship between R1 and R3 is already obtained in R3 Hardware address Fa0/20 1-4094 Then the test lines will be powered up for detection. It is found that the 2nd and 3rd lines match, but the matching length of the 2nd line is the longest, so the final result: RIP also supports tags , but it must be version 2 . VTP pruning Dampening takes effect only on EBGP routes and invalidates IBGP routes. 200 i Avoid routing loops with triggered updates Access-list 1 permit 10.1.1.0 ! ? In this way, the summary route inherits the detailed AS_PATH attribute, so atomic_aggregate is redundant. Therefore, in the above case, the generated summary route does not carry atomic_aggregate . Let's see: R 1.1.1.0/24 is possibly down, Start a TCP connection. Prepare enough resources when BGP is enabled ---------- !! The default VTP prunnig is off DHCP static address binding 1) Clear the MAC entries learned from all interfaces except the one that received the TC BPDU . Although this action may cause a brief burst of flooding in the network, it is also beneficial to refresh the CAM table and clear the stale entries. Http: Database agent URL Dual two-way point of the route re-release Solution: Use distribution lists to circumvent suboptimal path problems 101 1 The current status of the Port Status : Secure-up !! interface is up . Ip default-network 172.16.3.0 BGP cannot automatically discover the neighbors as the IGP . The IP address of the neighbor is specified by the local BGP neighbor command. The source IP address of the BGP connection is the outgoing IP address of the traffic . Note that only the neighbors locally configured IP and neighbors for BGP source connection establishment IP is the same, BGP connection in order to be properly established, at the same time,ccnp tshoot show run, to ensure that only one party can meet the conditions.
