Route 3 : AS_PATH : 500 5.5.5.5 Vlan 10 4.4.4.4 *Mar 4 07:02:23.473: DHCPD: relay information option exists, but giaddr is zero. If the route learns to an EBGP neighbor, it is reflected to all client and non- client IBGP neighbors. DHCP Troubleshooting 33 Option82 OPEN message If the result of the search finds an exact match, the data is forwarded according to the returned port number. !! Note the difference between the above two commands Dynamic Host Configuration Protocol Additional instructions: We see that on R4 , there are redundant paths for the two networks of 100.0 ,ccnp switch infrastructure security, but they are not best . Naturally, R4 cannot use these routes. Why is it not best ? The reason is that the next hop, nexthop is unreachable. The Layer 2 switch searches for VLAN configuration information based on the destination MAC address and VLAN ID of the frame, and determines from which port the frame is sent out. Commands The Permit/deny keyword has a different role in different deployment scenarios. 3.3.3.3 802.1q Routing table Protected port Atomic_Aggregate is a recognized self-determination attribute; Aggregator is optional. If the prefix does not match any entry in the prefix list, it will be rejected Then IOS will automatically change the command to Set ip next-hop ip1 ip2 ...... If R1 turns on auto-summary and network 1.1.1.0 mask 255.255.255.0 , it is still updated to R2 with details.

Note that the SVI port is a virtual interface and the routed port is a physical interface. The Layer 3 switch supports the physical interface as a Layer 3 interface similar to the physical interface of the router. The specific configuration is to enter the configuration mode of a specific interface. After the no switchport command is used, the interface becomes an L3 routing interface. You can Configuring IP for him is like operating an Ethernet port on a router to operate it.
