Shutdown your interfaces connected to FR cloud, save your config and reload
on ALL routers in your network connected to FR cloud. This should fix it
100% of the time. This is a quick way to get rid of this problem without
messing around with the config, and spending loads of time t'shooting the
network. You can do it first thing when going through your lab questions, or
when doing switching section (it shouldnt matter whether it takes 5 minutes
for the routers to come up, as you'd be busy doing other things).
Alternatively, save your config, change encapsulation to something other
than FR (e.g PPP), shut the interface down, change the encap back to FR, and
put your maps on etc, and unshut the interface. This could fix it as well.
In the actual lab, you'll need to make sure that there are no unwanted
mappings (0.0.0.0 or any other dynamically learnt ones to unwanted DLCIs),
otherwise it'd screw your L2 topology, hence screwing up everything else you
build on top.
Goodluck!
