HI Guys,
Situation is I have a spoke in DMVPN which needs to redistribute a couple of EIGRP routes into the cloud but the problem is that all spokes are in totally stub area which not allows you do inject any type 5 lsa. Is there any workaround?
Cheers.

Hi,
Can you change it to NSSA totally stub?
router ospf 1 Area 1 nssa no-summary

That depends on your constraints - I would assume you want to run EIGRP for filtering purposes...
I could think of the following:
1. Create a new area for that speciific spoke and make it nssa (most elegant).
2. Run EIGRP also on the HUB and redistribute there.
3. Could Static Routing (possibly with IP SLA) be of any help?
4. Create some tunnel between that spoke and HUB and run a routing protocol over that link (the ugliest solution :) )

It will require changing it on all spokes (30 routers). So theoretically it's possible but it's a complex change.
So if there is no easy workaround I will eliminate EIGRP completely on the branch site and run ospf instead.

Hi Traian,
It's just a single L3 switch at the branch with advertises all lan subnets to the dmvpn spoke router.
1. How can I create another NSSA arrea specifically for the spoke if I have a single /23 multipoint GRE on the hub? I cannot use the same interface for multiple areas can I ?
Thanks

Hi,
unfortunately no - you are correct; depending on whether you need to have spoke-to spoke connectivity you could either replace that tunnel or add a new one (can be point-to point)... or run eigrp all the way to the hub if static routes are not an option.
... or as you initially proposed add the new router to the OSPF domain.
Apart from the configurations above I can't think of any other setup.

Hello
Just to clarify - this DMVPN spoke is running ospf routing and is a stub , and now it become ASBR with eigrp?
