import vrf <vrf_name> vs route-map match source-vrf <vrf_name>
Hi, Is there any difference between "import vrf <vrf_name>" and "match source-vrf <vrf_name>" For example route-map myMap permit 1 match ip address prefix-list p1 option1: having "match source-vrf" in the same myMap route-map myMap permit 1 match ip address prefix-list p1 match source-vrf Vrf_red for vrf_blue: address-familiy ipv4 unicast route-map vpn import myMap rt vpn import 1111:11 import vpn option2: do not have "match source-vrf" in the myMap route-map myMap permit 1 match ip address prefix-list p1 for vrf_blue: address-family ipv4 unicast import vrf route-map myMap import vrf Vrf_red What is the difference in terms of routes filtering between the 2 options? Thanks, Bing
the command `import vrf XXX` under the address family in bgp tells bgp to take the routes in vrf X that are in that afi safi and to import them into this bgp vrf afi safi. the `match source-vrf XXX` command allows you to look at the originating vrf for when you are making a route-map decision. donald On Wed, Nov 13, 2019 at 9:19 PM <Bing.S@dell.com> wrote:

For example
route-map myMap permit 1
match ip address prefix-list p1
option1:
having “match source-vrf” in the same myMap
route-map myMap permit 1
match ip address prefix-list p1
match source-vrf Vrf_red
for vrf_blue:
address-familiy ipv4 unicast
route-map vpn import myMap
rt vpn import 1111:11
import vpn
option2:
do not have “match source-vrf” in the myMap
route-map myMap permit 1
match ip address prefix-list p1
for vrf_blue:
address-family ipv4 unicast
import vrf route-map myMap
import vrf Vrf_red
What is the difference in terms of routes filtering between the 2 options?

Thanks Donald. For the cmds under address-family, what is the significance of using "vpn", for example in option 1, route-map vpn import myMap, Also for a VRF to import/export routes with its remote peers, is rd&rt (rd vpn export, rt vpn import/export) a must configuration?
