>>
>>Hi all.
>>
>>Im Little confused at the labs, since looking at the beggining of all the
>>labs the task ask to disable frame relay inverse arp at the physical
>>interface and we simply create a frame relay map pointing to the next hop
>>ip address thus disabling the frame relay inverse arp, Things work with
>>successful pings from directly connected neighbors.
>>
>>Next topic of the same lab ask to enable ospf, and we change the interface
>>type based on the defined task, making the things work becoming
>>succesfully adjacent directly connected neighbors over the nbma cloud.
>>
>>Now.... at a far task, it prompts to enable frame relay traffic shaping at
>>a circuit level, mean a cir for a specified dlci, different to a cir of
>>another dlci, who both dlcis live in the same physical interface.
>>
>>Now there begins the problem, since we must configure the traffic shaping
>>characteristics (cir, bc, be) between different dlcis in the same physical
>>interface, we must change or dont know if it is better said "UNDO" some
>>configurations who are already working at the beggining tasks, for
>>example:
>>
>>config withouth the traffic shaping task (before traffic shaping):
>>
>>int ser 0/0
>>no frame relay inverse arp
>>frame relay map ip 192.168.1.3 100
>>frame relay map ip 192.168.1.5 200
>>ip ospf network point-to-multipoint nonbroadcast
>>
>>router ospf 1
>>neighbor 192.168.1.3 cost 95
>>neighbor 192.168.1.3 cost 170
>>
>>config with the traffic shaping task (after traffic shaping):
>>
>>int ser 0/0
>>no frame relay inverse arp
>>frame relay interface dlci 100
>>class SHAPE-DLCI100
>>frame relay interface dlci 200
>>class SHAPE-DLCI200
>>frame relay traffic shaping
>>ip ospf network point-to-multipoint nonbroadcast
>>
>>router ospf 1
>>neighbor 192.168.1.3 cost 95
>>neighbor 192.168.1.3 cost 170
>>
>>
>>Doing the configuration for the traffic shaping , involves changes of the
>>commands "frame relay map" resplaced with the command "frame relay
>>interface dlci", thus disabling the ospf neighbor relationship between
>>directly connected routers.
>>
>>ANY IDEAS?
