I want to configure CharyMying and Mandalay Router remotely.According to Topology,I will need dedicated point-to-point links(leased lines) to connect the branches.
Above Diagram is the simple topology.I use the frame-relay which is the packet switched technology because It is usually less expensive compared to leased lines.So,I use the cisco router as a frame-relay switch.The following is the topology goals;
- 100,101 and 200,201 of pairs must be point to multi-point PVC.(PVC=perment virtual circuit supported by provider)
- 102,103 pair is must be point to point PVC.
- 200.0.0.0/24 subnet is used for point to multi-point connections.
- 20.0.0.0/24 subnet is used for point to point connections.
- Lastly,All IP Address must be pingable.
I configure the frame relay switch first look like that the following;
Router>en //entering the enable router mode
Router#config t //entering the global configuration mode
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname FR-Switch
FR-Switch(config)#do sh ip int brief //Seeing the brief description of interfaces

I'm using the router as a frame-relay switch,now.So,I must choice the frame-relay switching mode.And than,I must define the DLCI numbers to each interface for PVC.
FR-Switch(config)#frame-relay switching //define the router as a frame-relay switch

According to Topology,I would like to use remotely to the branches from hard office(Yangon Router) only.So,no need to connect between the branches.No need to configure dlci between the interface of s1/0 and s1/1 of frame-relay switch.However,all interfaces of frame-relay switch must be DCE(Data Communication Equipment).

Another two routes have to be configured look like above.After configurations finish, frame-relay connections must be active.
In the picture above,frame-relay connection not active first.This is because the alternate configuration of outgoing interface dlci have not configured yet.Configure them look like from the picture.They will be active as like in the figure above.Following is seeing lmi(local management interface) type.I have used default lmi(CISCO).:)
Too long post.I shall stop here because it would be so boring that no one would not pay any attention.The next steps configuring IP Address,Routing,Telnet would be in next post.
