(Update 3/13) - I added "import ipv4 unicast map cff-internal-routemap" under one of VRFs interface with a prefix-list and route-map in order to redistribute OSPF into vrf enabled bgp. I see a little progress, but I am still not able to redistribute global OSPF to vrf BGP. ...

Azure MSSE (Microsoft Edge) ======================= (vrf1: coresite1 / vrf2: coresite2) Gateway --- internal sw(l3)
Hi, I have Azure ExpressRoute connected with edge (Gateway). Please see my attached photo for name. The gateway router is able to establish two eBGP session through two VRF interface (Coresite1 and Coresite2) which has two different RD. I do not have any issue between MSSE (Microsoft Service Edge) and gateway. Now I like to redistribute routes learned from internal switch (l3) which is connected through OSPF without VRF meaning that Gateway has two vrf interface toward MSSE while there is single connection to internal switch (L3). When I tried to redistribute global OSPF routes into vrf enabled BGP, it did not work because OSPF is not VRF enabled (there is only one connection, so I don't need vrf connection to internal switch).
Here are my questions.
1. OSPF to vrf-BGP redistribution--- I got %VRF specified does not match this router.
DC1-4451-ISR-01(config-router-af)#redistribute ospf 1 match internal
%VRF specified does not match this router
(Once I added import ipv4 / export imp4, it worked)
2. vrf-BGP to OSPF redistribution -- The below commend works, but I don't see route. I tried "redistribute bgp 6552 vrf coresite1 subnet" as well meaning that I put vrf names, but did not take it (show run does not show the vrf)
router ospf 1
auto-cost reference-bandwidth 10000
redistribute bgp 65522 subnets
I guess that I have to enable vrf on gateway? what am I missing?
Thanks.
