Re: Interface in multiple OSPF prcesses having multiple areas?

Steve,

This is never going to work ...
Even with the use of secondary IP addresses... but when using ISL it may work

It won't work on secondary addresses, but it will work on ISL
subinterfaces.

interface x
encapsulation isl 2
ip address x.x.x.X 255.255.255.248
ip address x.x.x.Y 255.255.255.248 secondary
ip address x.x.Y.Z 255.255.255.248 secondary
