Dumbass Section : Serial1/0:encaps failed on broadcast for link 38(BRIDGE)

#Topology#

#Symptom#
no ip traffic from 172.16.13.3 <-> 172.16.13.1
debug frame-relay packet on R3 gives following output

*Mar  1 15:32:12.917: Serial1/0: broadcast search
*Mar  1 15:32:12.917: Serial1/0:encaps failed on broadcast for link 38(BRIDGE)

#Resolution#
Ip routing was disabled from a previous configuration. It seems that IOS needs IP Routing enabled for encapsulation of IP packets on Frame Relay Links
Activate IP Routing on R3

R3#debug frame-relay packet
Frame Relay packet debugging is on
R3#ping 172.16.13.1 rep
R3#ping 172.16.13.1 repeat 1
