Re: Manipulating External EIGRP Distance

Hello Fahad,

The behavior of this command will be different when you will use any instead
of specific route source like this " distance 160 0.0.0.0 255.255.255.255 10
" . In this case it is changing AD of external routes. I am unable to
understand this behavior.

Regards,

Mujeeb
