Set community none router bgp 3 If an OSPF in- process route cannot be summarized: ------------------ 00:B0:64:04:09:99 Switch(config)# ip routing Use the match command to match a specific packet or route, and set to modify the packet or route related attributes. 17:57:27 2) Activate TC while timer , and then send the TC- set BPDU out from all non-edge designated ports and root ports . In this way, topology change information quickly floods the network. Protocol overview Ip community-list example 1 : After R2 show run , I found: OSPF can let R3 learn 1.0/24 and 2.0/24 routes. 1 network entries using 117 bytes of memory 1 path entries using 52 bytes of memory Neighbor table Aggregate-address 192.168.0.0 255.255.0.0 as-set advertise-map adv RIP redistribute default route Not advertised to any peer 200 100 Spanning-tree Origin attribute (priority: IGP > EGP > Incomplete ) The parameters and capability features are negotiated successfully. You start to send the Keepalive package and wait for the other party's Local origin Match x1 match x2 , x3 set Y This way the routing table: Weight LocPrf Public 201 200 100 Policy-based routing is more powerful and flexible than traditional routing. It allows network managers to select forwarding paths based on destination addresses and packet types, packet sizes, applications, or IP source addresses. R2#show adjacency detail In half-duplex mode, the CSMA/CD access method is adopted . The adjacency list in the CEF component is used for MAC or Layer 2 rewrite information. RFC2082 If R1 turns on auto-summary and network 10.0.0.0 , the subnet will be automatically summarized to R2. 200 201 300 The AD value of 11.11.11.0/24 is adjusted to be larger than OSPF , for example 130 . So the configuration is as follows: byte Match ip address prefix-list 1 set metric 200 Unreliable based on broadcast If R1 turns on auto-summary and network 1.0.0.0 mask 255.0.0.0 , it is advertised to R2 summary route 1.0.0.0/8 Another role of Gratuitous ARP is that some manufacturers use it to prevent ARP spoofing. For example, on some routers, a Gratuitous ARP- based anti- arp spoofing solution is configured, and the router (interface) will send Gratuitous ARP at a certain interval , in order to refresh the arp table of the bottom PC to keep the gateway IP corresponding. The MAC is always correct,ccnp switch cisco press pdf, of course, this anti- arp solution is quite awkward.
