The configuration of R2 is as follows: In the above output, the metric part of the red bold is the IGP metric that reaches the NEXT_HOP attribute address locally . We find that from R3 and R5 , the metric is 2 , then if we connect R4 to the interface of R3 , that is, F0/ 0 port OSPF Interface loopback0 R1(config)# access-list 1 deny 172.16.32.0 R1(config)# access-list 1 permit any LocPrf Let's take a look at R4. Configuration case Port-Security and Sticky MAC Address Represents a range. Matches only one of the characters contained in the range. Ip address 192.168.20.254 255.255.255.0 Redis ospf 1 route-map test 100 Switch(config)# ip route 0.0.0.0 0.0.0.0 192.168.255.2 Switch(config-vlan)# name Classroom Lead ( PreambIe ) Often used with the portfast feature on the interface for connecting to the host If the feature is not enabled on the local end, the data packet is either routed successfully or never routed out (discarded). 10.1.23.3 from 10.1.23.3 (3.3.3.3) What is an invalid arp entry: Neighbor 10.1.12.2 send-community or 标准Add a standard community-list entry 100 (empty), in other words,ccnp switch foundation learning guide 300-115, the MED will not be transmitted out of this AS Other configuration Each group of GLBPs can have up to four member routers as ip default gateways. These gateways are called AVF ( active virtual forwarder ). View and verify Bgp dampening half-life reuse limit limit limit maximum inhibition time ( 0xFFFF0000-0xFFFFFFFF ) is a reserved community value. In addition to these values, several well-known values ​​such as no-export , local-as, etc. are defined. For specific values, see RFC . We know that in a Layer 2 switching environment, a VLAN is a broadcast domain. Broadcast domains with different VLANs are generally different logical subnets, and they are isolated from each other and cannot communicate with each other. This can isolate broadcasts. effect. However, in actual networks, VLANs often require mutual access. For example, different departments of the same company are divided into different VLANs . If there is data exchange between these departments? Then the Layer 2 switch cannot be implemented, and it needs to use the Layer 3 device.
