Step 2 Basic CME Router Configuration

o.In this lab, you will be working with two routers. Connect to their console port and power them on. If the routers have a configuration already on it, erase the router and reload it.

p.Enter privilege exec mode.

q.Configure the hostname, passwords, interfaces, console and telnet access, eigrp routing protocol like the figure and make sure that both routers can reach each other. Use the ping command to troubleshoot, if necessary. The R1 and R2 configuration files are listed end of this document and your files should be similar to the listed here.

Note: Be careful. The 2800 series router has changed the interface naming convention.

Step 3 Voice CME Router Configuration

3.1 Preparing the Routers to handle the VLANs

Create and configure two sub-interfaces on the fastEthernet 0/0 of R1 and two sub-interfaces on the fastEthernet 0/0 of R2. They will be used by the VLANs configured on the switch.

On R1:

R1(config)# int fa0/0

R1(config-if)# no ip address

R1(config-if)# no shutdown

R1(config)# int fa0/0.10

R1(config)# encapsulation dot1q 10

R1(config)# ip address 10.10.0.1 255.255.255.0

R1(config)# no shut

R1(config)# int fa0/0.15

R1(config)# encapsulation dot1q 15

R1(config)# ip address 10.15.0.1 255.255.255.0

R1(config)# no shut

On R2:

R2(config)# int fa0/0

R2(config-if)# no ip address

R2(config-if)# no shutdown

R2(config)# int fa0/0.20

R2(config-subif)#encapsulation dot1q 20

R2(config-subif)#ip address 10.20.0.1 255.255.255.0

R2(config-subif)# no shut

R2(config-subif)# int fa0/0.25

R2(config-subif)#encapsulation dot1q 25

R2(config-subif)#ip address 10.25.0.1 255.255.255.0

R2(config-subif)# no shut
