SOO
Dear All,
What is the issue of SOO in EIGRP.
If Customer has two Link to Service Provider and If EIGRP-BGP redistribution is done on both edge router.
There is possibility of looping and in order to avoid that loop SOO is required .
IS it correct.

Yes, it prevents routes to re-enter via another PE if customer is dual homed or having Back Door Link
You are correct,
Here is good configuration example with explanation:

Good Luck
Which one is correct
i)
route-map SOO permit 10
set excommunity soo 112:1
!
int F0/0
ip vrf sitemap S00
OR
ii)
route-map SOO permit 10
set excommunity soo 112:1
!
route-map SOO permit 20
inf f0/0
ip vrf sitemap SOO
!
Both are same because you do not have any match statement in the route-map.
Based on your example, both are correct..
Dear All,
Defined SOO on edge routers but still I can looping problem .
What should be the sequence ? SOO first and then BGP-EIGRP redistribution or vice versa.
SOO value should be same or different.
As mentioned above, read this post and those questions should be answered. It was for me:
