mpls export map under vrf not working

[micfan]

Following config is not adding communities as under routemap.

any ideas as to why.

I posted some show outputs but it gets blocked as spam.  May try to add in next reply.

VRF and routemap names have been changed.

vrf definition xxxxcom
rd 65411:1
route-target export 65411:1120
route-target import 65411:1121
route-target import 64511:1120
!
address-family ipv4
export map export1
exit-address-family

ip prefix-list export1 seq 10 permit 10.10.10.192/27
ip prefix-list export1 seq 20 permit 10.10.10.224/27
ip prefix-list export1 seq 30 permit 10.10.11.192/27
ip prefix-list export1 seq 40 permit 10.10.11.224/27

route-map export1 permit 10

I saw it additive keyword.

[micfan]

it's there in posted config under routemap export1.  Did you miss that in post or am I missing something else?

Thanks for reply!

[micfan]

first show command shows export map set

second however does not show the RT being added to route.

Hi @micfan ,

Is the following path imported from another VRF or is it from the same xxxxcom?

> 172.29.254.247 (via vrf xxx) from 172.29.254.247 (10.102.1.138)

Regards,

[micfan]

that route is in the VRF and is best.  The first is  an imported route to that host from another site that is over MPLS that is second best path.

There three paths and best is from vrf not local to this vrf. This make rt appear as I mention below rt import of vrf this prefix learn from.

Hi @micfan ,

Is it possible that you applied/modified the export map after that path was learnt via eBGP?

If so you might need to perform a "clear bgp vrf xxxxcom ipv4 uni 172.29.254.247 soft" to make sure this path is processed via the export map.

[micfan]

Thank you harold looks like that is all it was!!  I thought this would reset in time on its own.

THanks

[Harold Ritter]

You are very welcome @micfan and thanks for the feedback

[MHM Cisco World]

Can you remove import RT:65411:1120

From vrf and check community rt again.

[MHM Cisco World]

Show ip bgp vpnv4 10.10.10.192/27

The rt appear is rt import from other vrf not export of xxxxcom

But let be more check 

[micfan]

no I just didnt scrub the real VRF name.  Thats the local VRF and the proper export tag.

I should be more careful posting..

[MHM Cisco World]

show ip bgp vpnv4 vrf xxxxcom 10.10.10.192/27

Can you share this ? 

[micfan]

I think I shared it as you were asking
