Subject: Frame Relay Map Help
> I am working through Caslow's Bridges Router and Switches book and I am
> trying to get a firm understanding of frame-relay.
>
> I have generally recreated the lab on page 126 with the minor changes of
> adding another router and changing addresses. For those without the book
> (which is very good by the way) this is frame on physical interfaces in a
> hub and spoke configuration.
>
> The hub can ping all spokes, and each spoke can ping the hub. However,
> spokes can not ping each other until the 'frame-relay map ip" statement is
> added to point to each spoke.
>
> Everything can now ping everything else. Now we save the configs and
> reload.
>
> Since map statements have not been added on the spokes to point to the hub
> (since they were originally learned dynamically) I expect that dynamic
> inverse arp to be disabled, and there will be no dynamic entries on the
> spokes for the same protocol and the same dlci.
>
> This is not the case in my lab.... here is the relevant part of the config
> on one spoke, and the results of 'show frame-relay map'
