Omar,
The default route is not labeled by default. You need to use the command
"mpls ip default-route" to change this behavior.
Cheers,

Subject: [c-nsp] default route Label
Hi List,
I'm working on a pre-production MPLS network, I'm using ISIS as IGP and
LDP, so far, the ISIS learned routes are labeled, and apparently all
work fine. Rightnow I've generated a default route via
default-information originate command into a PE router after the others
P learned the default route, but I've figured out that default route is
not labeled. Is it a well behavior? or maybe I'm a wrong. Is possible
labeled a default route?
