Hi
I see an issue with this approach. If you do not know which prefix under
what domain (i.e. eigrp or ospf etc, you might get some prefix dynamically)
before hand than how do you identify those prefix and assign distance. Also
this approach is suitable for wise distribution of ip address. Otherwise
access-list will be long and difficult to maintain.
Any flaw in my thought?
thank you - Arif
