DHCP relay experiment ICMP redirects are always sent 2 S 172.16.0.0/16 [1/0] via 172.16.3.0 S 172.16.3.0/24 [1/0] via 172.16.23.3 Note that although R4 passes the route 400 {100 , 200} , the AS in the braces is only calculated as an AS in the AS_PATH calculation. Therefore , the two EBGP routes received on R6 have the same AS_PATH length. Finally, R6 The route of the oldest EBGP neighbor will be preferred . RootGuard R4#sh ip b 100.0.1.0 Ip prefix-list 1 permit 11.11.11.0/24 ip prefix-list 2 permit 12.12.12.0/24 route-map RP1 permit 10 There are 2 forwarders (1 active) Address-family ipv4 unicast Length : indicates the full length of the BGP packet, including the header. Router(config-dhcp)#network [network address][subnet mask] Encapsulation Status Aggregate-address summary address as-set advertise-map Since the flash space is very limited, it is recommended to store the file on the TFTP server. When deploying on a TFTP server, be careful to first create an empty file to correspond to the URL in the configuration command . This file is used for dhcp snooping bingding database writes (depending on the device). *Mar 1 00:11:47.951: ICMP: echo reply rcvd, src 2.2.2.2, dst 192.168.123.3 Basic VLAN concept TYPE DHCP-SNOOPING VERSION 1 Switch(config)# ip default-gateway 192.168.255.254 !! Set the gateway for the access switch itself 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,ine ccnp route workbook, you must execute the policy on the AS border router. The switch forwards the DHCP packets carrying the Option 82 information to the DHCP server. basic concept Redistribute ospf 1 route-map test You can further configure this logical etherchannel interface. 100 Neighbor 10.1.12.1 remote-as 100 On R1 , ip route 1.0.0.0 255.0.0.0 null 0 then ip defaut-network 1.0.0.0 , then R2R3 will learn the default route [Start fast exchange] That is to say, R5 goes to 100.0.1. and 2.0 each has two paths, which are through 10.1.25.2 and 3.3.3.3 , and finally R5. Set ip next-hop verify-availability The distribution list is deployed in a link state routing protocol such as OSPF . If the out direction is to be used, it can only be used in such a situation. Network 8 V1 uses broadcast, which is sent every 30s by default , using UDP port 520 (source, destination port) Switch(config-if)# switchport trunk native vlan ? Ip dhcp snooping Eliminate routing loops by horizontal splitting Load balancing ? Last update from 192.168.34.3 on Serial0/1, 00:09:32 ago Routing Descriptor Blocks: Note that the above is the default metric when re-publishing from other dynamic routing protocols into this routing protocol . If you republish a local direct connection or a static route, the situation changes, as follows: Distance vector routing protocol At another point, R2 will take 10.0.0.0 , 11.0.0.0 (the network segment where the secondary address is located), and 1.0.0.0 and 3.3.3.0 from their own loopback. Look at the top of topology, AS300 has a subnet 172.16.1.0/24 , AS400 has routes 172.16.2.0/24 . 200 i Edge port edge ports AS65102 as a transit region ( trasit AS ), the AS inside BCDE running the OSPF , such that AS within reachable; D and C did not run Origin IGP, metric 0, localpref 100, valid, external, atomic-aggregate , best R1 release A network routing, R3 will learn this OSPF routing; Additionally, R2 also learned, assuming R2 deploy OSPF to RIP routes redistributed, which eventually route R3 will pass RIP also learned, then R3 will At the same time , the route is learned from RIP and OSPF . R3 will optimize the OSPF route. Because OSPF has a small AD , OSPF re-releases it to RIP without causing a suboptimal path problem.
