Comment 7 for bug 1684622

@Vivek: The fix https://review.opencontrail.org/30625 is not in 3058 containers yet.
I checked that the controller.conf in your setup now has the required parameters in the required syntax. Please try this in the next build which has the above mentioned fix.

FYI: the relevant snippet contrailctl/controller.conf after you changed the JSON
%<----------------
root@nodea10:~# cat /etc/contrailctl/controller.conf

[CONTROLLER]
external_routers_list = {'blr-xm1': '10.204.216.253'} <------ the new parameter as required.
encap_priority = VXLAN,MPLSoUDP,MPLSoGRE
