[c-nsp] IOS-XR tftp copy via vrf?

[Jason Lixfeld]

I'm trying to get an ASR9K/XR 4.1.0 to shoot a file to a tftp server that lives inside a vrf:

!
tftp client vrf management source-interface Loopback21949
!
interface Loopback21949
 description Loopback for Management
 vrf management
 ipv4 address 10.219.49.2 255.255.255.255
!

RP/0/RSP0/CPU0:router#ping vrf management 10.219.51.130 source 10.219.49.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.219.51.130, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

Anyone see what I'm missing here?
