No shutdown exit Dhcp-bindings all —Logs all packets that match DHCP bindings. supplement: The route to the LOOPBACK interface. PVST+ Router bgp 64512 no synchronization no auto-summary Configuration Example Untitled-1 Switch(config)# spanning-tree portfast default Other solutions, we will continue to introduce in the following experiments ( 802.1D is always 0 ) OK , now go back to the main class network number 172.16.0.0/16 , then we will go out and look at the picture. 172.0.0.0/8 actually shifts the mask of this class B address to the left by 8 bits , so that the network number obtained is actually a large network number including 172.16.0.0/16 . Call it supernet . If the route is marked d , it means that the route is suppressed. If it is h , it means that the route has signs of flipping. DHCP relay As a result, R6 will receive summary routes from R4 and R5 , respectively : 172.16.0.0/16 The mapped ethernet vlan will be blocked Switch(config-if)# ip address 192.168.255.1 255.255.255.0 When a BGP router sends a route update to its EBGP neighbor, it cannot carry the LP attribute. The LP value of the EBGP route received by the peer is empty. The above command creates a policy-list ; the Policy-list can only contain a match statement. Set default interface specifies how to send such a packet Ip prefix-list 1 permit 1.1.1.0/24 route-map test 201 200 100 BGP based policy accounting on input is disabled BGP based policy accounting on output is disabled Hardware idb is FastEthernet0/0 ? In this experiment, we define AS345 as a federated AS , R3 ,cisco ccnp switch book, and R4 as member ASs , using 64512 as the AS number, R5 as a member AS , and 64513 as the AS number. Router bgp 345 Y Priority 120 (configured) If the switch does via a untrust interfacing a downstream switch, and release of the desired received by the interface, with a downstream switch sends out option82 of DHCP messages, use the global command: IP Information Option DHCP Snooping the allow-Untrusted , while Because it is a DHCP packet received through the untust interface , a DHCP snooping binding database entry is created based on the result of the interception .
