Re: exporting partial routing table

Thanks Tyson. Here is what I am trying to achieve and commands:

export only 100.100.100.0/24 (blueVRF) routes into RED vrf

ip vrf RED
rd 1:1
route-target export 1:1
route-target import 1:2

ip vrf BLUE
rd 1:2
route-import 1:1
export map BLUE
route-target import 1:1

route-map BLUE
  match ip address 1

access-list 1 permit 100.100.100.0 0.0.0.255

now the qusetion is with below config:
a) will it only export 100.100.100.0 subnet (acces-list 1)

ip vrf BLUE
rd 1:2
route-import 1:1
export map BLUE
route-target import 1:1

OR

I still need below 3 commands to export specific route.

ip vrf BLUE
rd 1:2
route-import 1:1
route-export 1:2 <---------------this command +
export map BLUE <----------this command +
route-target import 1:1 <-----------this command

thanks
