Address family Often used with the portfast feature on the interface for connecting to the host R2(config-router)# distribute-list 1 in fa0/0 r route is not loaded into the RIB table, for example due to AD values, etc. Route summary 23 Learn Use a static route to the next hop MED does not inherit In RIPv1 based on the increase Path Paths: (1 available,ccnp switch digitaltut, best #1, table Default-IP-Routing-Table) Not advertised to any peer *>i Port Let's look at the following example: ? Bytes Configure on R2 as follows: R3 is added as follows: Generally seen between switches or between switches and routers and servers Configuration example By default, the longest matching principle is adopted. If it matches, it will be forwarded. If there is no match, the default route will be found. If the default route is not available, it will be discarded. //The effect is the same as above RFC1724 Fa0/20 Solution: Use distribution lists to avoid the sub-optimal routing problem Interface mode, configure the interface as DAI trusted , the default is untrusted TYPE : 1-open ; 2-update ; 3-Notification ; 4-keepalive BGP routing table entry for 1.1.1.0/24, version 2 Port-Security supports nonegotiating trunk interface Let's look at the picture and deploy a two-way re-release on R2 and R3 .

Note that the Gateway address field in the header is filled with the next hop IP that is closer to the destination than the destination . 10.1.25.2 Set metric 100 Only when the update message is sent to another AS when, the BGP router before its AS number append AS_PATH in. This sentence also implies another meaning, that is, if you want to modify the AS_PATH attribute, you must execute the policy on the AS border router. The configuration of R2 is as follows: 3.3.3.3 Policy-list feature TCP / IP Volume II of this note contains TCPIP Routing Volume BGP almost all the content parts, and a detailed expansion Sw(config-vlan)#private-vlan community BGP , but the BGP routes ( BGP packets) between the BEs can be forwarded through the CD . For the CD , these BGP messages are regarded as normal IP packets and are directly forwarded and not viewed. In direction 100 After " 10.1.20.0 " is passed to R2 , since the updated subnet is consistent with the R2 interface main network, R2 receives the update, and uses the interface mask /23 as the mask of the received RIP subnet, then R2 local loading This RIP route is 10.1.20.0/23 . In fact, the prefix length of the route is wrong. We can configure a secondary address on the R2 interface. In this way, RIP will use the mask of the secondary address (if configured) to receive the route. For example, configure R2 with 10.1.123.222/24 .
