BEGIN Paths: (1 available, best #1, table Default-IP-Routing-Table) Not advertised to any peer When the interface is up/down , all dynamically learned MAC address entries will be cleared. The statically configured secure address entries remain. Receiving behavior Reposted FAQ 49 Dhcp-bindings permit —Logs DHCP-binding permitted packets. Origin IGP, metric 0, localpref 100, valid, external, multipath Show ip bgp You can also configure DAI to discard the Ethernet frame source MAC and ARP body in the MAC illegal inconsistent ARP . This is followed by a further introduction. Aging Type : Absolute SecureStatic Address Aging : Disabled 9 Weight Via 10.1.13.3, FastEthernet1/0, 0 dependencies TCP/IP volume one End deny any Route-map first acquaintance Switch(config-if)# ip address 192.168.255.1 255.255.255.0 VLAN field, 15 bits are currently used 10 th, then the support up to 2 of the 10 power = 1024 th VLAN OSPF . In this way, for R4 , it goes to 192.168.1.0 , there is a sub-optimal path , that is, around the long way, take R2-R3-R3-R5 16 bits Then, if an OSPF process (this sentence may not be rigorous, everyone understands what I mean), the route can not be summarized, such as the following figure. Sw1(config)#interface port-channel 1 // Enter port-channel group 1 to configure IP R4 on the show ip bgp 172.16.0.0 ------------- <0-4294967295> 32-bit tag value aggregate-address 192.168.0.0 255.255.0.0 as-set after, R1 can only learn to 2.0 , the summary route are rejected, the reason is 1.0 carries no-adver of Community Community , when the summary route plus the as-set keyword after Will inherit its community , so the summary route also carries no-adver , this time The new routing table is typically sent to neighboring routers on a regular basis, and the triggered update is sent immediately in response to changes in the routing table. Route-map The configured commands are simple: BGP Deaggregation Baby giant frame is larger than the standard MTU 1500 bytes, but less than 2000 bytes // The offset value is increased by the value displayed in the normal route entry. It is added on the original basis instead of replacing the original hop count. Policy-list feature Verify set ip default next-hop 1,20,30 Generally done at the AS boundary, tell yourself the local-pref value from within AS . The larger the Local_Pref ,ccnp switch networktut, the higher the priority Enable DHCP snooping on SW1 without going to no ip dhcp snooping information option , which is to insert option82 . The configuration of other devices is the same as the previous experiment. It is found that the PC cannot obtain the address . The debug message will be found on the gateway device, that is , debug on SW2 : relay information option exists, but giaddr is zero . The giaddr field means the IP address of the first DHCP relay agent that the message passed .
