well, not an easy one as ISIS will always advertise all IP addresses on
an ISIS-enabled interface. you could play around with
"advertise-passive-only"/"no isis advertise-prefix" and redistribute
connected with a route-map to filter the prefix you don't want, but this
rather cumbersome.
Why don't you want to advertise the secondary address?
