[j-nsp] Advertising MPLS LSPs into IGP

Traffic engineering bgp-igp will just copy inet.3 routes to inet.0 for
use of forwarding locally.  If you want to advertise a LSP in your IGP
you should use forwarding adjacencies.  (in your case configured under
IS-IS)

Here is a sample config:

lab at SanJose# show protocols 
mpls {
  label-switched-path green {
    to 192.168.2.1;
    primary one;
  }
  path one {
    192.168.5.1 loose;
  }
isis {
  interface all {
    level 1 disable;
  }
  label-switched-path green {
    level 2 metric 3

Hi All,

I think I need some clarification on this issue or some correction in my
configuration.
I have bidirectional (RSVP signaled) LSPs, with every hop specified
(taking the exact same paths in both directions for simplicity), created
like this:

Psyduck --- M160Top --- Jynx
Psyduck --- M160Top --- Jynx --- Abra
Abra --- Jynx --- M160Top



                                            Lo0 = 1.2.3.2
               |--------------------- 4.4.4.2 Psyduck  1.1.1.1/30
----------------------------------|
               |
|
               |
|           
(Lo0 1.2.3.3) Abra
-------------------------------------------------------------------
6.6.6.1/30 M160Top       (Lo0 1.2.3.1) 
		   |
|
               |
|
               |
|
               |------------------   3.3.3.1/30 Jynx 2.2.2.2/30
-----------------------------------|		
			                           Lo0 1.2.3.4


Just trying to see if my LSP is being advertised in the IGP (ISIS). I am
using the "traffic-engineering bgp-igp" command under " Protocols MPLS".
Below is the database (all L2 for simplicity) from M160Top but I don't
see where Abra has included the LSP so that it could be used by M160Top
or other any other router in the SPF calculation if needed.
Configuration available if needed.
