By default, the Cisco IOS DHCP server and relay agent features are enabled on your router The range is 1-255 / / Set the interface mode to Trunk mode Gratuitous ARP , the free ARP is a special ARP Request/response message, that is, the Sender IP is the same as the Target IP (usually used for IP collision detection). Next Hop Router bgp 123 This is a very typical case. In the above figure, the network environment is like this. Suppose we have two routers, R1 and R2 , connected to the server farm. The server farm uses two three-layer switches to hang the network server. We have planned two subnets for production of 10.1.1.0/24 and office 10.1.2.0/24 . R3 is the access router. R1 , R2 , and R3 run OSPF . A frame whose type field is 0806 represents an ARP protocol frame. Note that community is not sent by default and must be send-community . Topology change process Router bgp 200 Switch(config-if)# spanning-tree [ vlan vlan-id ] port-priority pri Discard the illegal ARP packet, the switch will discard the illegal ARP after log Paths: (1 available, best #1, table Default-IP-Routing-Table) Flag: 0x820 The weight of the BGP route generated by the local summary is also 32768. 1.1.1.1 (metric 129) from 2.2.2.2 (2.2.2.2) For details on the BGP neighbor table field, see the show section of the BGP Configuration section of this document. DMZ-Link Bw 193 kbytes is an extended community attribute, so if you want to pass this value to the just IBGP neighbor in the AS , you need to add send-community and add the extended keyword. Access-list 1 deny 192.168.13.0 access-list 1 permit any Show ip bgp route prefix // 100: 200 indicates that this is for the AS200 's Local Suppression list Although route-map is called , route-map can only be used for matching, not for setting attributes (cannot use set command) Three-layer exchange Total number of bindings: 1 Send TCP packet AD Switchport port-security mac-address sticky 00b0.1111.2222 RIP redistributes default route 110 RFC1723 defines an acceptance control switch R2 , R3 , aiming RIP create static routing domain summary route, point null0 , while only these static routes redistributed into OSPF , and indeed can play a sub-optimal paths to avoid the question, but: AS100 sends 10000 routes to R2 . If R2 only wants to collect 100 routes and the rest is filtered, then the general practice is to execute the in- direction filter on R2 ,ccnp tshoot drag and drop, because AS100 is uncontrollable for AS200 . However, this method is actually a waste of link bandwidth and network resources. Fast switching is superior to process switching, it uses a route cache ( route cache ) for storing information about a stream of data (Flow) specific information , The EBGP route should be better. I saw R5 and went to see R3 : Debug ip dhcp server {events | packets | linkage} Enables debugging on the DHCP server When 10.1.1.2 is reachable, the track object is true As shown above, R1 , R2 , and R3 run RIP . In the initial situation, R2 will update its routing table to R1 , which assumes that there are three routes 1.0 , A strange phenomenon has appeared. It seems that R4 does not reflect the route from R5 to R3 . Why? In theory, the RR will learn from non- client of IBGP neighbor to route reflection to their Client , but it is clear, in this experiment, R4 and did not learn from R5 route reflection to their Client . Ip route 100.0.0.0 255.0.0.0 null0 10.1.12.2 IGP 3.3.3.3 (metric 65) from 3.3.3.3 (3.3.3.3) The above command means to inject the detail route defined in map1 in the local BGP RIB when the summary route matched by map2 is normal . When the summary route hangs, this detail disappears. This is called conditional injection . Below we look at the details of these two route-map , these need to pay special attention. Router bgp 300 The following figure is the sender using the route-fresh message to push the prefix-list Troubleshooting 33 ACL 70 The mask of the destination address. * i100.0.1.0/24 R3 's gateway is R1 , R1 itself has static route to 2.2.2.2 , and the next hop is R2 . Note that this is an MA network. All three interfaces are on the same network segment. This is critical. R3 will go to 2.2.2.2. When the data is dropped to its own gateway 192.168.123.1 , R1 finds that the next hop of the data is 123.2 on the same network segment as the local inbound interface after searching through the routing table , so he thinks that 123.
