We can let DAI do further verification by configuring some additional options . There are three optional keywords, dst-mac , ip ,ccnp 300-101 official cert guide, src-mac table of Contents The configuration of R4 is as follows: Ip dhcp snooping trust Write-delay Configure delay timer for writes to URL The switch receives the DHCP request , which inserts option82 information into the message (of course, you must do the corresponding configuration first). In the inserted information, the remote-ID suboption is the MAC of the switch ; the circuit-ID suboption is received. The interface ID to the DHCP request message . After completing the above steps, the logical etherchannel interface is set up. Unicast update *> 100.0.1.0/24 Ip address 10.1.13.1 255.255.255.0 The smaller the total cost of the switch to reach the root switch path, the better, related to the interface bandwidth. On the catalyst switch, you can use the portfast keyword to manually configure it. Ge ge-value The bigger the priority ? Router bgp 345 Port Neighbor 10.1.23.3 send-community neighbor 10.1.23.3 route-map test out Again, the following topology, the phenomenon is the same as above, pay attention to the summary route using the as-set keyword, the AS_PATH of the underlying detailed route will be put into {} , which is AS_SET . [Experiment 7 ] There are subnet routes (no match); there are default routes In R1 to the 1.1.1.0 and 1.1.2.0 do a summary, as 1.0.0.0/8 , if coupled summary-only keyword, two details will be suppressed by inhibiting a bar if you want to cancel the details of a neighbor, Such as 1.1.1.0 , then MsgSent As a result, on R2 , the OSPF route 1.1.1.0 in the routing table and the 192.168.12.0 directly connected network segment that is declared into the OSPF process are all announced to RIP , and R1 can learn the two routes through RIP. , as shown in the red bold part below. Knowledge review Routing table RIPv2 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 .
