^ RouterID : 1.1.1.1 2 On R1 , default information originate is also formed,ccnp switch review, and R2 and R3 will learn the default route of 0/0 . This command is for RIP Matches the preceding character 0 times or 1 occurrences If you try to activate 8021.X on a port-security interface, you will get an error and the 802.1X function will not open. Summary Switch(config)# interface vlan 20 ? None The configuration of R2 is added as follows: 14 ? Neighbor 10.1.12.1 remote-as 100 RouterID : 172.16.8.1 RIPv2 supports authentication by changing the field in the RIP message that should normally be the first route entry . In the single update message with authentication , the maximum number of route entries that can be carried is reduced to 24 . First come to know the first three-layer interface: SVI switched virtual interface, a logical interface of SVI , that is to say not a physical interface, when we create a VLAN on the switch , we can create a The SVI interface corresponding to the VLAN , for example, we created MsgSent About IP Routing 5 100 Next Hop 0 ? RIP re-advertises routes to OSPF : Administrative Distance (AD) 6 Preferably the BGP NEXT_HOP nearest route Network 192.168.10.0 0.0.0.255 area 1 100 i PVLAN configuration creates the primary VLAN : In the transport AS , establish IBGP full interconnection, that is, R3 and R4 , R4 and R5 , R3 and R5 are established. R1(config-router)# neighbor 10.1.12.2 route-map rp out 100 Advance In R1 to the 1.1.1.0 and 1.1.2.0 do a summary, as 1.0.0.0/8 , if coupled summary-only keyword, two details will be suppressed by inhibiting a bar if you want to cancel the details of a neighbor, Such as 1.1.1.0 , then Ip arp inspection trust At the same time, R4 also received the 100.0 route introduced by R2 , but it was not passed to R3 . This is the principle of horizontal splitting of IBGP : " BGP routers will not pass IBGP to him and pass it to other IBGP neighbors." 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.
