I have two 2801 routers populated with VWIC-2MFT-T1/E1 card in each. I have configured routers using commands as below.
controller e1 0/2/0
clock source internal
channel-group 0 timeslots 1-31
These commands brought a serial interface up dynamically which I have configured using the following commands.
interface Serial 0/2/0:0
ip address 192.168.100.1 255.255.255.0
The above configuration is done on one of the router and the other router is configured in the same way except the ip address (i.e. the IP address on the other router is 192.168.100.2 255.255.255.0)
The intention is to connect the routers back-to-back and check the connectivity. By configuring the router in the above way, the Serial interface of both routers changes their status as well as Protocol to UP status. But still I am not able to ping the peer end router by logging into one of the router.
So, I tried to ping the serial interface of the router in which I was logged in. Strangely, I am not able to ping the local Serial interface itself.
Am I missing out any configuration? Any configuration example will also help.
