Not able to make this work. Any thoughts / hints appreciated.
R2 -- (L2) -- R5 -- (L1) -- R6
R2 advertising 133.9.2.0/24 and 133.8.0.0/16 (summary)
R5 advertising 133.9.5.0/24
R6 advertising 133.9.6.0/24
Should R6's routing table should have a 0.0.0.0/0 route to R5? It does not.
CLNS routing enabled on all interfaces, all adjacencies are up.
R2 and R5 sharing all routes just fine.
From "sh isis database" R2's L1 ATT bit to self is set, no other ATT bits are set (would expect one on R5)
R6 only sees an L1 route from R5 (loopback0)
Also tried default-information-originate on R5 (is it necessary??) but only R2 sees it, not R6.
How can the 0.0.0.0/0 route be made to only advertise to L1 peers?
Running 12.2.16b.
Thanks, AP
