VRF lite redistribution C3750 12.2(55)

I'm having an issue doing VRF route leak on a 3750. I'm only getting one way redistribution. The following configuration is a snippet of what should be required for it to work

ip vrf EDGE
rd 65000:10
route-target export 65000:1
route-target import 65000:2
!
ip vrf WEB
rd 65000:20
route-target export 65000:2
route-target import 65000:1
!
router eigrp datacenter
!
address-family ipv4 unicast vrf EDGE autonomous-system 1
!
topology base
redistribute bgp 65000 metric 1000000 1 255 1 1500
exit-address-family
!
address-family ipv4 unicast vrf WEB autonomous-system 2
!
topology base
redistribute bgp 65000 metric 1000000 1 255 1 1500
exit-address-family
!
router bgp 65000
!
address-family ipv4 vrf WEB
no synchronization
network 1.4.0.0 mask 255.252.0.0
exit-address-family
!
address-family ipv4 vrf EDGE
redistribute eigrp 1 metric 100
exit-address-family

In the vrf EDGE I get the 1.4.0.0 route from WEB, working as intended. In the vrf WEB I am not getting any of the EIGRP routes from. Is there a platform limitation or what am I missing?   

The following snippet is from GNS3, where the redistribution is working both ways. Same configuration design. 

ip vrf EDGE
rd 65000:10
route-target export 10:20
route-target import 20:10
!
ip vrf WEB
rd 65000:20
route-target export 20:10
route-target import 10:20

Hello Kasper Mortensen,

What routes do you have in vrf EDGE that are not imported into vrf WEB ?

  • show bgp vpnv4 unicast vrf EDGE
  • show bgp vpnv4 unicast vrf WEB
  • show ip route vrf EDGE
  • show ip route vrf WEB

Best Regards.

Hey,

I just pulled out another 3750 of same model and IOS and the configuration is working correctly on that one. So I guess the issue is semi closed.
