LAB: Frame Relay Address Resolution using inverse-arp

DLCIs

R2=205,206,215,216,225,226

R5=502,506,512,516,522,526

R6=602,605,612,615,622,625

LAB Requirements:  no DLCI indicated in the diagram: donot use PVC with 0 & 1 in the middle

note: you can issue the command below to clear some dynamic arps
clear frame-relay inarp

from R5 to reach R6 must add static mapping

frame-relay map ip 100.100.100.6 522

from R6 to reach R5

frame-relay map ip 100.100.100.5 622

frame-relay map ip 100.100.100.6 622  ===if u wan to ping urself

useful tool: to ensure that l2 to l3 mapping is ok, or if there is encapsulation failed
debug ip packet

extra: adding dynamic routing
