Hello
For some reason, I am not able to ping PCs in either side of LANs. I am able to ping routers and PCs from router, but not from PC to PC. My network is very simple with two sites in different cities, connected with L3 MPLS. The Cisco Routers are 2911
Site A: 172.17.1.0/24 (Router IP = 172.17.1.1)
Site B: 172.17.2.0/24 (Router IP = 172.17.2.1)
Ping from Router (172.17.2.1) to 172.17.1.51 is fine
Ping from Router 172.17.1.1 to 172.17.2.5 is fine
But when I ping from 172.17.2.5 (PC in Site B) to 172.17.1.51 (PC in Site A), it does not work. Router A configuration is
