[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.
