Disable IPv4 routing for routing-instance?

Hello list,
  Junos provice a method to disable isis ipv4 routing support like this:

isis {
        no-ipv4-routing;
}

However,we want to disable ipv4 routing for an VRF like that,is there
any method for us to do so?
Thanks a lot.

You might want to try checking out the Juniper-NSP mailing list for future
questions of this nature -

But while we are on the topic, you can disable the IPv4 routing for a VRF
with the following:

'set routing-instances <instance-name> protocols isis no-ipv4-routing'
