Purpose: Configuration redistributed to achieve interoperability between hosts
Subjects: six router, four PC,
Experimental environment: GNS3, CRT
Principle :: ASBR route ospf redistribution of
Experimental Procedure:
1. Drag six router and 4 single PC to the topology area, a good place
2. configure the router attributes, each have 128M increase disk capacity, configuration service board, there are 16 I configure Layer 2 service board
3. Open the interface information, connection configuration of experimental data, remember to check again 
4. Experimental analysis of the first wave of thinking:
Topology map, OSPF has two regions, namely AREA0 backbone region and non-backbone areas AREA 1, the non-backbone area directly connected to the backbone area, play the role of connecting the both sides are aggregated data is exchanged by R1; So R1 is ABR , Rl also need to 59.56.61.0 segment and an outer segment 192.168.1.0 own area AREA1 and AREA0 injected, the injection is so between different protocols, it is ASBR
AREA0 ring backbone area and RIP, that is connected between the AS two, R2 need to be injected into the link state rip AREA0 in AREA0DE1OSPF also need to rip injected into the link state, the R2 is the ASBR , R5 only need rip agreement declare their network can
R3 is arranged in AREA 1, the other branch is attached to a section of a straight-through outside the region, there is a non-directly connected network segment, R3 also played a role in the ASBR , R4 only needs to configure a default route, the things you can do to R3
R6 is a foreign operator's network by the device, the company's information with outside information 59.56.61.0 forwarding each other, R6 only connection with the company's R1 router, so just give R6 configure a default route to R1 things to do can,
Through analysis, to understand the function and role of each router, the next is the use of the command, which is also an objective of this experiment lies, multi-input commands, faster memory
5. Next Step, or to the interface with IP address of each, it should be noted here, the increased need to start forwarding Layer 2 interfaces can configure the interface
PC, simply, to ignore the PC, router configuration from a 1-6 start
First click on Run
R1:
Here F1 / 0 no success, say f1 / 0 on l2 links, this NO switchport
Show the Brief ip interface then do 
R2:
R3:
R4;
R5:
R6：
Interface configuration is complete, the next start configuring routing
6.R1 is ABR: f0 / 0 interface, and F1 / 1 Interface in AREA0
f0 / 1 in the AREA1, F1 / 0 with the ISP directly connected, the straight-through injection period, the injection static routing,
R2: R2 is the ASBR: In addition to declaring each in which area, but also the summary information for each area to another area of the interface injection
R3: F0 / 0 directly connected network segment, there is a static route, R3 and static routes need to be declared directly connected network segment is not within the area AREA 1; f0 / 1 in AREA 1, this status need to be declared 
R4: comprising two directly connected network segment, and that is at the tip of the network, and only a link leading to it, so you can set a default network sent out,
R5: the rip, the only declared their own directly connected network segments can be
R6: Similar with R4, mainly configured article summarized network segment,
Configured, then began a wave of ping
Perfect, thank you
