When will a Netware Server or Cisco router use their internal address
of 0000.0000.0001 and when will they use their MAC address as the node?
Or are the possibilities predictable?
Also : I have only been able to filer NLSP routes during
redistribution. Not comming in/out of a router.Which I think is per
design. I used ACL 12xx. I cannot, however, deny some routes and permit
"all". (-1). That just seems to toggle them as internal NLSP or
External NLSP. The only way I can make the filter work is to permit all
the routes I want redistributed and then deny all.
I ask this here becaue this was one of the very few IPX threads I have
seen here.
