While doing Lab #13 using a 2521 and three other 2500 series router, I
managed to get the same output, but at the hub router (Router A).
RouterA#sh frame map
Serial0 (up): ip 0.0.0.0 dlci 210(0xD2,0x3420)
broadcast,
CISCO, status defined, active
Serial0 (up): ip 0.0.0.0 dlci 200(0xC8,0x3080)
broadcast,
CISCO, status defined, active
I believe this happened to me because,
I already had the FrameSwitch and the 2 spoke routers configured, up and
running, and then I powered up the Hub Router and configured it.
***
Explanation: Unfortunately the router I'm using as a hub router is an
AccessPro card stuck in a PC, so it's a bit more difficult to get to and
configure, so I saved it for last. In other words, it's just pure
happenstance that the powerup sequence dictated that I powerup and
configure the Hub router, last. When performing labs from the CCIE Lab
Study guide, I always boot to a clean router, "erase start; reload", skip
the initial setup configuration, paste my basic router configs and then
paste the lab scenerio from the book.
Anyway, once the hub router was powered up, I configured the S0 interface
and the results posted above is what I get when I issue the "sh frame map"
command.
I solved the problem by rebooting the router with S0 configured and saved
to NVRAM and viola, I have a properly working HUB router.
RouterA#sh frame map
Serial0 (up): ip 192.1.1.3 dlci 200(0xC8,0x3080), dynamic,
broadcast,, status defined, active
Serial0 (up): ip 192.1.1.4 dlci 210(0xD2,0x3420), dynamic,
broadcast,, status defined, active
But I'm not satisfied that reloading the router is the only way to solve
the problem.
I did some research, and found the "clear frame-relay-inarp" command,
clear frame-relay-inarp Clear inverse ARP entries from the map table
but it doesn't seem to clear the table as advertised, atleast not in the
configuration and IOS version I'm currently running (120-6 IP only). I
haven't gotten around to trying a different version of IOS yet.
Maybe some here can shed some light on why the command doesn't work as
advertised.
