As per this note in WB 1 : "Frame Relay Inverse-ARP packets are link-local to the layer 2 process, and
cannot be forwarded between different circuits. This means that when R1 sends
an Inverse-ARP request out to R5 on DLCI 105, R5 cannot turn around and
forward this request to R3 on DLCI 503. The result of this is that R5 can resolve
R1 and R3 via Inverse-ARP, R1 and R3 can resolve R5 via Inverse-ARP, but R1
and R3 cannot resolve each other through Inverse-ARP. To gain reachability
between these devices a static frame-relay map command must be used to
populate the layer 3 to layer 2 resolution table." : R1 & R3 can't resolve each other by inverse-arp but as per following output it looks like R1 & R3 are able to resolve each other. do you guys know why they are able resolve each other by inverse-arp? what's convergence time for inverse-arp? sometimes I've to wait upto 4-5 mins. btw, I'm using GNS3 + GNS3's builting FR switch.
