Re: community VRF scenario

Some more data here...

I see it working (I see routes from one VRF into the other) but the thing is
I only see SOME routes.

This is the original VRF's ip route table (names and addresses have been
changed to protect the innocent)

      10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
> C 10.23.129.184/30 is directly connected, GigabitEthernet0.72
> L 10.23.129.185/32 is directly connected, GigabitEthernet0.72
> 17.62.0.0/24 is subnetted, 2 subnets
> B 17.62.105.0 [20/0] via 10.23.129.186, 03:05:17
> B 17.62.106.0 [20/0] via 10.23.129.186, 03:05:17
> 172.17.0.0/28 is subnetted, 1 subnets
> B 172.17.0.32 [200/0] via 20.15.231.1, 03:05:17
> 20.62.53.0/32 is subnetted, 2 subnets
> B 20.62.53.61 [200/0] via 20.15.231.1, 03:05:17
> B 20.62.53.62 [200/0] via 20.15.231.1, 03:05:17

This is the destination VRF that was supposed to receive ALL routes:

      17.62.0.0/24 is subnetted, 2 subnets
> B 17.62.105.0 [20/0] via 10.23.129.186 (VRF_A), 03:07:11
> B 17.62.106.0 [20/0] via 10.23.129.186 (VRF_A), 03:07:11

I am using a export map route-map matching all the subnets (there are hits
to all of them) and setting the extcomm to a new RT that is being both
exported at the source VRF and imported at the destination VRF, as we can
see here:

sh ip bgp vpnv4 vrf VRF_B 17.62.105.0
> BGP routing table entry for 1234:5555:17.62.105.0/24, version 534
> Paths: (1 available, best #1, table VRF_B)

> Origin incomplete, localpref 100, valid, external, best
> Extended Community: RT:1234:4444 RT:1234:5555

Why are the others not being inserted as well? I receive both 17. subnets
from one BGP peer on this router, while the others I receive from a
different peer... nevermind the connected ones
