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?

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
