[j-nsp] MPLS LDP

[sunnyday]

Hello I have configured mpls ldp in my network and I want all ip traffic to
go through mpls.

I have issued the command mpls ldp ip-forwarding but the traffic seems to go
through isis when I trace route to an ip I see  no label assignment.

After that I have issued the mpls ldp ip-forwarding hosts-only and all /32
traffic was going through mpls but all the /30 or other subnets 

Where going through isis.Any help would be appreciated.

Thank you
