Single ISP with multiple WAN subnets shared between vDOMS?

[thrasos_l]

Say I have an ISP that routes me additional public IP blocks via: 1.1.1.1/30

Public routed IP blocks:

2.2.2.2/27

3.3.3.3/27

The wan interface is currently associated to VDOM: A  

Is there a way to to share the 3.3.3.3/27 subnet with VDOM: B ?   I tried a emac-vlan link but that doesn't seem to allow me to route to the primary interface via the subinterface.

The way I would normally handle this is creating VLAN interfaces on a switch or router and serve them up to each VDOM as needed.

Thanks,

If I'm understanding this right, it seems like you could definitely create an inter-VDOM link between A and B, and put in a static route in VDOM A sending 3.3.3.3/27 to VDOM B via that link.  This assumes then that VDOM B uses the link as its default route (or at least part of an SD-WAN).

This does not avoid the traffic traversing VDOM A (i.e. go straight from ISP to VDOM B), if that's what you're trying to accomplish.  Pretty sure that wouldn't be possible without the ISP providing a separate /30 to VDOM B and routing 3.3.3.3/27 via that instead.
