Route map for specific LAN to be exported in a route-target

Level 1

Hello

I may lab I am trying to configure router Loc1Office1 to export only LAN 10.1.0.0/24 to route target RT 65000:100 (this is route target for shared services)

However, using my config, it looks like all LANs are exported into this RT, not only the one I want. 

Attached is the config of my environment. 

The main idea of what I am trying to achieve is in these lines. 

 

ON Loc1-Core1 router
conf t
hostname Loc1Core1
!----------------------------------------------------------------------------------------------
! For Loc1Office1 VRF I create a list which will allow only LAN to reach Shared1VRF, not Guest
!----------------------------------------------------------------------------------------------
ip prefix-list PL-Loc1Office1-1 permit 10.1.0.0/24
route-map RM-Loc1Office1-Export-1 permit 10
match ip address PL-Loc1Office1-1
set extcommunity rt 65000:100 additive
exit

vrf definition vrf-loc1office1
description vrf for office 1
rd 65000:1
route-target export 65000:1
route-target import 65000:1

route-target import 65000:2
route-target import 65000:3
!bellow import from loc1shared1
route-target import 65000:100
!bellow import from loc1internet1
route-target import 65000:101
address-family ipv4
!Export the map so that the Guest LAN does not show up in shared1 VRF
export map RM-Loc1Office1-Export-1
exit
exit
sh bgp vpnv4 unicast vrf vrf-loc1office1 10.1.0.0










vrf definition vrf-loc1shared1
description vrf for shared services
rd 65000:100
route-target export 65000:100
route-target import 65000:100
!bellow import from locations

route-target import 65000:2
route-target import 65000:3
!bellow import din loc1internet1
route-target import 65000:101
address-family ipv4
exit
exit


Any tips much appreciated.

Best regards!

ip prefix-list PL-Loc1Office1-1 permit 10.1.0.0/24
route-map RM-Loc1Office1-Export-1 permit 10
match ip address prefix-list PL-Loc1Office1-1<- prefix-list
set extcommunity rt 65000:1001 additive <-different RT that not match your router-target export 65000:100

ip prefix-list PL-Loc1Office1-1 permit 10.1.0.0/24
route-map RM-Loc1Office1-Export-1 permit 10

Thank you!

This did the trick

match ip address prefix-list PL-Loc1Office1-1<- prefix-list




The idea was to present 10.1.0.0/24 into 65000:100 while 10.1.0.0/24 and 10.1.1.0/24 would be present into 65000:1
