Hi Experts,
I built the network like attached diagram, and hoping it to work like this:
the traffic coming from outside, which is VLAN 1, will pass through ASA and go to VLAN 100 and 254.Routing protocol between R0, ASA and R1 is OSPF.
The problem now is that, router R1 can already see all the route information but cannot ping/telnet to R0 or internet. I tried with acl but it doesn't work. Kindly please have a look with the configs below:
