VPNV4 Redistribution

[feroz syed]

Hello,

R8 and R16 are EIGRP neighbours VRF X.

R3 and R8 vpnv4 neighbours.

Inside core OSPF running on all Routers.

Now R8 want to send the customer routes to R3, but R3 not receiving any routes from R8, but R8 has customer routes on VRF X table. now R8 want to redistribute the routes to ospf or BGP.

i tired using under the bgp but no routes on R3 side.

Any suggestion would be appreciated.

you need 

check if R8 have route in VPNv4 with command 
show ip bgp vpnv4 all

if you confirm the R8 have route, then you need 
config iBGP under VPNv4 address family between R8 and R3 
config import/export under VRF of both R8 and R3, I usually use in lab 
route-target both 100:100

UNDER bgp 
address-family ipv4  <<- this need to be in same VRF OF eigrp

redistribute eigrp 100 metric 20

[feroz syed]

<<- this need to be in same VRF 

why ?

R8 and r16 are just Eigrp neighbors,

R8 and R3 vpnv4 and redistribute connect already executed but why do i need to create vrf on ipv4 address-family.

[MHM Cisco World]

address-family ipv4 vrf X autonomous-system 100 <<- BUT i see EIGRP vrf-aware, so to make bgp accept the route the address family ipv4 also vrf-aware 

[feroz syed]

R8 already has customer routes on vrf table, both side Bgp and Eigrp mutual redistribution already done.

now R8 need to send routed to R3 via bgp vpnv4.

but above you saying ,if am understand correctly, you telling me to create vrf adress-family under bgp to send routes across vpnv4 neighbor

Hi @feroz syed ,

As @MHM Cisco World , you need to put the redistribute eigrp statement under "address-family ipv4 vrf X" under BGP.

correct.

[feroz syed]

it's working, but my question is here below we already making mutual redistribution from bgp to eigrp and eigrp to bgp

but why we need

address-family ipv4 vrf X
redistribute eigrp 100 metric 2

R8#sh run | sec eigr
router eigrp 100
!
address-family ipv4 vrf X autonomous-system 100
redistribute bgp 321 metric 1000 10 255 1 1500

router bgp 321
bgp log-neighbor-changes
no bgp default ipv4-unicast
neighbor 3.3.3.3 remote-as 321
neighbor 3.3.3.3 update-source Loopback0
!
address-family ipv4
redistribute eigrp 100 metric 20

[MHM Cisco World]

address-family ipv4 vrf X
redistribute eigrp 100 metric 2
!
address-family ipv4 vrf X autonomous-system 100
redistribute bgp 321 metric 1000 10 255 1 1500
!
address-family ipv4 <<<-- no need 
redistribute eigrp 100 metric 20

Hi @feroz syed ,

Because for the VRF routes to be redistributed in VPNv4, you need to put the "redistribute eigrp" statement under the vrf section, rather than the global section.
