There are two ways to perform an inbound soft reset: 1. Soft reset using stored routing update information 2 , dynamic soft reset Address family identifier. When the value is 2 , it indicates the IP protocol. Interface vlan 10 Select the route with the smallest neighbor IP address ( the address of the neighbor in the neighbor configuration of BGP , that is, the update source IP of the neighbor ) No synchronization no auto-summary R2#show cef interface f0/0 FastEthernet0/0 is up (if_number 4) The default is 180s , which can also be called expiration timer time limit timer or timeout timer. V2 defaults to send v2 to receive v2 Troubleshooting 39 BGP re-released to IGP 12(_34)?_56 Path Identify the type of message: Interface vlan 10 Redis static route-map cisco 1.1.1.1 (metric 129) from 2.2.2.2 (2.2.2.2) 1 Continue to look R4 result of the capture ( R3 distributed to R4 of BGP update package): Router bgp 300 4.4.4.4 Encapsulate the ISL header and the new FCS on the basis of the original data frame BGP stipulates that routes learned through one IBGP are not propagated to all other IBGP neighbors. This is the horizontal split rule of BGP . Multi-vendor routing environment RIPV1 operating behavior Local origin Set metric 100 2 IBGP re-advertises routes to OSPF 3.0 this route. This is an example of the use of a distribution list. Of course, it has a wider range of applications. As shown above, R1 , R2 , and R3 run RIP . In the initial situation, R2 will update its routing table to R1 , which assumes that there are three routes 1.0 , Ip dhcp snooping information option allow-untrusted Ip route 10.1.2.0 255.255.255.0 10.1.254.1 Match ip route-source R1 Initially, R3 can learn three loopback routes from R1 and 192.168.12.0/24 routes. Now we don't want R3 to learn the route to 192.168.3.0/24 , then we can configure it on R2 as follows: BGP neighbor : When two routers establish a TCP- based BGP connection with each other , they are called neighbors or peers. When the neighbors just establish a connection, they exchange all the candidate BGP routes, but after the initial route exchange, the incremental route update is usually sent only when the network information changes, and is not periodically updated. Active is local Router(config)#ip dhcp excluded-address 172.16.1.100 172.16.1.103 Ip community-list 11 permit 100:11 ( 802.1D is always 0 ) Route accurate summary algorithm Vtp pruning is off by default When a network is directly connected, the interface is not "activated" and attempts to establish a neighbor relationship. BGP neighbor relationships need to be manually ? Remote-ID type Switch(config)# vtp password x ? 100 [Experiment 1 ] There is a main class route; there is a default route, and the main class route is taken. The GW configuration is as follows: Authentication Ip community-list 11 permit 100:11 Determine if the frame has a VLAN tag . The range is 10 - 1000000 Ip prefix-list ABC seq 5 permit 172.0.0.0/8 ge 24 Remote-ID suboption fields 16 bits Eliminate routing loops by horizontal splitting Now we consider that when R1 originates an OSPF internal route, both R2 and R3 can learn this route. Then on R2 , the route is re-released from process 1 to process 2 , and finally R3 will learn the route from R4 . So for R3 , the dual OSPF process, SW1(config-if)# switchport trunk allowed vlan ? 100 / / Modify the default parameters Route filtering or execution strategy during redistribution 100 If both neighbor 1.1.1.1 weight and neighbor 1.1.1.1 filter-list 1 weight xxx are used , the latter is preferred To be a whole, that is, to see the cluster as a whole. Metric The following uses an example to illustrate the application of SSAP and DSAP . Assuming that Terminal System A and Terminal System B are to use a connection-oriented and reliable data transmission service, the following process occurs: Ip route 172.16.3.0 255.255.255.0 172.16.12.3 Interface loopback0 Origin IGP, metric 0, localpref 100, valid, external, multipath , best ? Neighbor 10.1.12.1 remote-as 13 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: Port-Security violation penalties The network learns the route learned from the IGP routing protocol into BGP . The MED value inherits the metric in the IGP protocol. If the interface is trunk , set the trunk protocol type Router bgp 12 Total number of bindings: 1 Passive-interface defualt In 802.1q the native vlan is untagged, using Dot1q switches all unmarked frame is forwarded to the native vlan in the ISL on all data frames, including native vlan encapsulation, so if the package is not received The data frame will be discarded (the ISL does not have the concept of a native VLAN ).

After R12 learns the route, it finds that BGP attributes (including AS_PATH ) are lost. Because OSPF redistributed into BGP , the default does not automatically tag values are copied into the AS_PATH , the need to R11 on The out- direction policy cannot be used separately for the member of the peer-group . It can only be used for the entire group . The in direction does not have this restriction. All neighbors in the same peer group must be all iBGP neighbors or all eBGP neighbors. Established In the output of Show and more , you can use the pipe character | with a regular expression to filter the output. Includes 7 -byte preamble (a string of 1 , 0 intervals for signal synchronization) and a 1 -byte frame start delimiter ( 10101011 ) *> 172.16.0.0 Send TCP packet 200 i Federal configuration and implementation Ip address 3.3.3.3 255.255.255.0 The IBGP neighbor relationship is as shown in the figure. The neighbors are built using their respective loopback ports. After receiving the route, R2 continues to pass the IBGP neighbor R3 . In this case, R3 is the RR . Therefore , the route sent by the non- client IBGP neighbor is forwarded to its client R4 . At this time, R3 adds the ORIGINATOR and CLUSTER_LIST attributes to the route. , where the ORIGINATOR attribute is R2 's routerID is also 2.2.2.
