8 bits Ip address 5.5.5.5 255.255.255.0 (Note that in the actual environment, the situation may be quite different). Below, let's look at an example: Type echo protocol ipIcmpEcho 10.1.1.2 source-ipaddr 10.1.1.1 frequency 10 Origin IGP,ccnp tshoot v7, metric 0, localpref 100, valid, external, atomic-aggregate , best Path The OSPF metric on R4 going to 3.3.3.3 becomes 101 , which is larger than the metric going to 5.5.5.5 . Therefore, R4 goes to If the penalty value exceeds the pre-set threshold - the suppression limit: the penalty value reaches this threshold, the route is suppressed, ie not released, until the N half-life, the penalty value is reduced to another threshold: re-use threshold (de-suppression threshold) ), the suppression of the route is lifted. Metric Management VLAN in a Layer 3 switch environment In another case, the idea is still the same, RR and Client 0 , regarded as infinity Port number 521 ORIGINATOR_ID and CLUSTER_LIST To summarize on R3 , use aggregate-address summary-only as-set , then the BGP table on R3 : Another recommended solution is to adjust the management distance of the routing protocol: Then 1 , 2 compare first, 1 is preferred (because 1 has a smaller MED ); since 1 and 3 are in the same AS , so again Limit of inhibition: 2000 The redistribute local route learned from the IGP routing protocol enters BGP , and the MED value inherits the metric in the IGP protocol. 1.1.1.1 If you do the following configuration on R2 : Route reflector planning principle A sends a data frame to B requesting to establish a reliable connection-oriented connection. ... * i 100 This path. And because there is no RIP route in the routing table , the natural RIP re-release to OSPF fails, and even worse, R4 about 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. 86025 Distance 130 2.2.2.2 0.0.0.0 1 R3 AS_CONFED_SET A list of unordered AS numbers on a path to a specific destination , using the method with AS_SET 0 packets, 0 bytes switched through the prefix tmstats: external 0 packets, 0 bytes A After receiving the response, you know B has established a connection with their locally. A also opens up an SAP value to indicate the connection, and sends a confirmation to B to establish the connection. We can R4 use the bgp always-compare-med command to force R4 compare routes MED Further, the summary is transmitted to the route D after, D will continue to B to pass, and as summarized route from C , thus reaching D of AS400 R4 OSPF and IBGP route re-release BGP path attribute Obviously this method is too poorly scalable. Go ahead and assign the interface of SW1 and SW2 to the PC to vlan10. Passed between peers . If the route attribute of the route received between EBGP peers carries Local Preference , it will be triggered. Ip helper-address 192.168.100.1 Re-advertise routes between different OSPF processes R1 , R2 , and R3 run RIP , and 1.1.1.0/24 on R1 is not directly announced. On R2 : On R2 : Difficult to resolve Ip as-path access-list 1 permit _600$ route-map setCommu permit 10 Different OSPF between two-point two-way process re-release, can also use a static summary route re-issued, respectively, in two ASBR create different static routes summary above, re-publish static summary routes in the corresponding processes. BGP routing table entry for 11.11.11.0/24, version 2 Interface fast0/1 DNS , WWW , and SMTP servers belong to the same subnet Note that this is just a basic authentication feature, not encryption. 3.3.3.3 Switch(config-if)# ip address 192.168.20.254 255.255.255.0 Bridge ID of the root bridge RFC1771 A Border Gateway Protocol 4 CISCO Private Agreement Route-map test permit 10 match interface Serial0/0 router ospf 1 MacAddress If you configure the following, then the COST comparison will exceed the weight and become the most preferred comparison rule. After 10.1.31.0 is passed to R2 , since R2 takes the mask of the receiving interface and finds that 10.1.31.0 has a position of 1 in the host part , the subnet is stored in the routing table and treated as a host route. : 10.1.31.0/32 Match comprising 100 and 200 of AS_PATH Ip dhcp pool BIND Detailed rules EtherChannel There are two ways to perform an inbound soft reset: 1. Soft reset using stored routing update information 2 , dynamic soft reset 1> Soft reset using updated routing information Second column > Optimal path selected by BGP algorithm TRUNK ? Interface vlan 20 AFI (Address family identifier) basic configuration Data forwarding mode 13 Network 100.0.1.0 mask 255.255.255.0 FastEthernet FastEthernet IEEE 802.3 LoopGuard Set ip next-hop verify-availability [ next-hop-address sequence track object ] Exactly the same, except that the list of AS numbers belong to the local Federation AS Trunking The Ip helper-address command is configured on the Layer 3 interface that receives the broadcast discovery packet sent by the client , or "blocks" the broadcast DHCP packet. For example, if it is a Layer 3 switch, use the access. interfacing PC , then you should configure the VLAN 's SVI interface. Distribute-list 1 out ( Well-known mandatory ) .
