I'm trying to export a cirtain routes from CustA to MGMT with help of following route-maps on router RR
ip access-list standard MGMT
permit 192.168.100.0 0.0.0.255
route-map MGMT permit 10
match ip address MGMT
set extcommunity rt 100:999 additive
for the test purpose a loopback interface was configured on R1 in CustA VRF with IP from 192.168.100.0/24 subnetz.
All routing information are correctly distributed over all routers, but export doesn't work - the IP from 192.168.100.0/24 doesn't get the additionla RT 100:999.
If I configure the "export-map" in VRF configuration on R1 then the export works perfectly - 192.168.100.0/24 gets additional RT 100:999 and it's then imported by the router RR in VRF MGMT.
But, as far as I understand the export should work exactly in the same way if I do it only on RR router, shouldn't it ? I mean if take a real life network - we don't want to configure that export-map on all PE routers for all VRF, it should be enough if we do it centrally - on the router-reflectors.
Re: MPLS/VPN route leak configuration between VRFs
that is true, RRs do not actually export the routes, rather reflect them and hence this feature is not applicable on those(unless one has a VRF with the interfaces being advertised on a RR). I would go for a route-map under VPNv4 address-family to achieve what you need.
On a side note, this might be worth looking into -
