I am having problem with static routing.
I have two router connected from yangon to singapore.
For Yangon router, 1 serial (220.127.116.11/28), 1 fe port (192.168.11.2/24).
For SG router, 1 se and 1 fe.
My problem here is I connected one PC to Yangon router fe port via switch and assign same subnet with router fe port.
Then, I try to ping Yangon fe port and se port. ok...
But i can not ping to sg router serial port. I did routing in sg router and i could not figure out what is the problem. i already check access list as well there is no deny for echo reply.
