Situation 1 Recognized as a self-determination attribute. LP is the local priority and is used for Update messages between internal peers ( IBGP ) , but not to other EBGP neighbors. The larger the LP value, the higher the priority. Due to the existence of the principle of horizontal splitting, BGP requires that the IBGP be fully interconnected within the AS (here, the neighbor command specifies). (The root cause is in Both R1 and R2 are connected to the 2.2.2.0 network. At this time, R3 goes to ping 2.2.2.2 . Because the static route of the outgoing interface is used, R3 thinks that 2.2.2.0 is a locally connected network, so ARP request is sent , R1 , R2 , can receive the request message, and both respond to the request message (the premise two Router bgp 100 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. This has already been said before.

It can be understood as a weight value. The larger the priority, the higher. The value is in the range 0-65535 . switchport trunk encapsulation dot1q switchport mode trunk Matching with the detailed route 172.16.32.0/24 , so eventually these two routes will be filtered out, which is inconsistent with our needs. In fact, this is the drawback of using a standard ACL to match the route, you can only match the network number of the route, and can not further match the prefix of the route. We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows The preferred principle is IGP > EGP > Incomplete 200 i Path In the ORIGINATOR_ID , then it is known that a routing loop has occurred , so the route is ignored. 100 Elect a root bridge in a switched network For dynamic address allocation Route poisoning Establishing IBGP full interconnection, the configuration is relatively simple, has been involved in the above experiments, let us look at how to achieve through the route reflector. The idea is very simple. We configure R4 as RR and R3 as the client of R4 . In this way,ccnp tshoot gns3 lab download, R4 acts as the RR and will reflect the route learned from Client R3 to R5 . It will also learn the route from IBGP neighbor R5 . Reflected to ClientR3 .
