i have ...
2 core routers...... with many VRFs....
and some distribution switches.....
For this case/problem , let me describe it in simple works .
I have one vrf CERT-NDC and another vrf NDC_ITA
now the problem...............................
I am getting route 10.25.12.128/25 in vrf NDC_ITA , which i want to be
imported in CERT-NDC and i did a import export already, and since i have 2
cores CR01 and CR02, when i do show ip route vrf NDC_ITA and show ip route
vrf
CERT-NDC i can see the 10.25.12.128/25 route learning and imported from
NDC_ITA
vrf...
BUT.......................................
As i said we have some distributions...........i have 1 distribution for
NDC_ITA and 1 distribution for CERT-NDC.....there i have some import export as
well , but
on distribution level , i am seeing the 10.25.12.128/25 in vrf NDC_ITA but i
am not seeing it in similar distributino of CERT-NDC.....
I am attaching the 4 configs to let me know what can be the possible problem !!!
Copy pasting CR-01 AND CR02 and also copy pasting the DS-R03 and DS-R05 .....
" plz note that i wanna learn and see the route 10.25.12.128/25 in CERT-NDC
vrf.....this is the objective !!!

PLEASE H3LP.............................. "I am not able to learn
10.25.12.128/25 subnet on distribution CERT-NDC , but same CERT-NDC on core01
and core02 i am able to see route 10.25.12.128/25 , which is coming from
NDC_ITA to be exact and learning from EXTERNAL SERVICE PROVIDER....
