global route-map setting for bgp daemon within VRF is missing.
BGP daemon default vrf:
set protocols bgp route-map 'route-map'
BGP deamon within VRF
[email protected]# set vrf name vrf-name protocols bgp route Configuration path: vrf name internet protocols bgp [route] is not valid
Looks like this option is missing. Global route-map is perfect to rewrite source ip.
Can you fix that?
