[c-nsp] Secondary IP address on isis interface

[Tantsura, Jeff]

Hi Oliver,

Thanks for your help.
It's a migration case where primary and secondary addresses belong to
different sources. Sounds weird :) but this is of course temporary.

I'll try to play with what you have suggested.

Thanks,
Jeff

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?
