[j-nsp] About ISIS export policy behavior

[Pyxis LX]

Hi, All.

I'm a little confused by the default ISIS export behavior in JUNOS.

According to this:
https://www.juniper.net/documentation/en_US/junos14.1/topics/concept/policy-routing-policies-actions-defaults.html

ISIS/OSPF default export policy should "reject everything", which
means it should be equivalent to a policy like this:

policy-statement reject-all {
    then reject;
}

However when I apply this export policy to protocol isis, all non-iso
routes, including lo0's inet/inet6 addresses are not advertised in LSP
anymore.

Shouldn't these routes be advertised by flooding? Or did I miss something?

Thanks!
