A macro command that specifies the interface mode as access and enables the portfast feature. The above command, the switch will accept the carry option82 information while giaddr is 0 the dhcp message, and then do the relay. In this way, the address can be successfully obtained. Define matching criteria Ip dhcp pool BIND SW1 and SW2 are configured as VTP mode client ; SW3 is configured as VTP mode Server FastEthernet0/0 ? 7 Router bgp 200 As a result , the BGP table of R5 becomes as follows: Two routes, on R2 we introduce these two routes using re-release : Configuring the sample EIGRP environment 16/32 bit Forward Delay time listening to the learning state, or learning state to forwarding state required time defaults to 15s . Understand the invalid arp entry The configuration of R4 is as follows: Router ospf 1 Configuration case The boundary will change, so if you make an AS_PATH modification policy for IBGP neighbors , it will be nonsense. Router bgp 200 bgp dmzlink-bw SW3 receives this BPDU , but finds that this BPDU is less preferred than its own locally stored BPDU , so the BPDU is ignored. When both the primary and secondary addresses exist, RIP will use both the primary and secondary addresses as the source to send routing updates. So R1 and R3 will learn the routing update of 2.2.2.0 . But R3 ca n't learn 1.1.1.0 , on the one hand, because R1 sends updates to R3 and is ignored by R3. After DHCP snooping is enabled on the switch , the switch uses the DHCP interaction content that is "listened" on the untrust interface to form a table: Set comm-list del delete route-map test permit 20 3.3.3.3 Keepalive package. Received WAS, IT A SENDS that the LAN containing the BPDU DATE The up-to-Port Information Stored for that. the In the this Way, the inferior IS Discarded Information,ccnp switch lab guide, and Superior Information The IS ON propagated Network. " In 802.1q the native vlan is untagged, using Dot1q switches all unmarked frame is forwarded to the native vlan in the ISL on all data frames, including native vlan encapsulation, so if the package is not received The data frame will be discarded (the ISL does not have the concept of a native VLAN ). Let's look at the above scenario, focusing on the egress router. This egress router is a three-layer link with the Layer 3 switch. Therefore, you need to configure the backhaul route to the intranet, which is the red font part in the above picture. In this scenario, There are only three network segments on the intranet, so three static routes are configured, but what if there are 100 network segments? Do you want to have 100 routes? As a result, the routing table becomes very large and bloated, which is very inconvenient to maintain and manage. More importantly, this undoubtedly wastes resources of the device. Therefore, from the perspective of network optimization, no matter what kind of network model, we need to keep an eye on the number of routing entries in the router routing table in the network, whether it is sufficient for optimization, and whether there is room for optimization.
