Re: IS-IS and OSPF redistribution

Im not sure if you need to config a explicit mapping of clns over
frame-relay PVC. With your config over point-to-point sub-interfaces, I
mean frame-relay interface-dlci XXX, you ar getting the map IP/DLCI with
frame-relay inarp, but I'm not sure if you also are getting the map
CLNS/DLCI in order to transfer CLNS routing packets over frame relay
link between R1 and R6. Have you checked it?
With multi-point subinterfaces, you have to config frame-relay map clns
<DLCI-number> broadcast to it works!
