Hi;
I missed out some information
The adjacency can not be formed only spoke to spoke, frame map or inverse arp d
oes not make any difference, try both alreay, broadcast in frame map statment.
The adjacency can be establishe betwen hub and spoke 1, hub and spoke 2.
All subnet mask are in 24 bits, sorry for my mistyping.
PS. It's valld Frame Realy configuration. But I just want to see this configua
tion will work if configuration OSPF.
TIA
Vincent
