That's useless since isis is natively totally stubby.
That means that if a L1 router wants to send a packet outside its area, it
will send the packet to an L1/L2 router of its own area.

Objet : Default route in ISIS
Group,
I am having no success advertising a default route from an L1/L2 ISIS
router to an L1 ISIS router.
Ex: R2 (L1/L2) ----------------------- R1 (L1)
I am using the default information originate command on R2 above. By
default this operation will create an L2 route to 0.0.0.0 which will not
be advertised to an L1 router, so I am using a route-map to make it an
L1 that will be advertised to R1....but it never makes it. Sample
config below:
R2:
clns routing
router isis
area 49.0010.2222.2222.2222.00
default-information originate LEVEL1
route-map LEVEL1
set level level-1
ip route 0.0.0.0 0.0.0.0 null0
int s0.1
ip address 192.168.3.2 255.255.255.0
frame-relay interface-dlci 101
R1:
clns routing
router isis
area 49.0010.1111.1111.1111.00
is-type level-1
int s0.1
ip address 192.168.3.1 255.255.255.0
frame-relay interface-dlci 102
I just typed these sample configs into the e-mail so please ignore any
typographical or minor syntax errors...I am just trying to paint a
clearer picture of what I am trying to accomplish.
This is defintiely not an NBMA issue. The routers form an adjacency
and pass other L1s between them.
My problem is strictly with the default-information originate command
and getting the L1/L2 router to advertise the default route to the L1
router.
Any help?
Thanks,
Adam
