Tag rewrite with Fa0/0, 10.1.12.2, tags imposed: {} Must be zero Configuration Revision 15 The process learns the external route, so the update source here is R2 . Next-hop , the next-hop is changed to the update source IP of R3 , which is the loopback interface IP. Configure BPDU is 0x00 and TCN BPDU is 0x80. A frame whose type field is 0835 represents an RARP protocol frame. Set traffic-index 30 BGP must be identifiable, update messages can include The configuration of R2 is as follows: Gateway implementation) If the route is marked d , it means that the route is suppressed. If it is h , it means that the route has signs of flipping.

R3 is passed to other BGP neighbors. However, this summary route loses all the attributes of the underlying detailed route. Among them, AS_PATH is the most critical, because once the AS_PATH attribute of the detailed route is lost , this summary route is very likely to generate a routing ring. road. Therefore, it is necessary to let R3 warn the downstream BGP peers , tell them that 1 , this is a summary route, 2 , where the summary route occurs, that is, the originating AS and the originating router of the summary route .
