RE: vrf-mtu-check; Thanks, yes J-series its applied automatically, the
M-series I'd already applied it manually. Also tried enabling
ICMP-tunneling, but still no luck :(

Any ideas how to debug?

Thanks, Tim.

the vrf IP address is drawn from among the IP addresses associated with
interfaces configured for that routing instance. so you meet that

to enable path checks on the outgoing interface for unicast traffic
routed on a VRF routing instance, you may need to include the
vrf-mtu-check statement under chassis.
