[cisco-voip] CUBE across VRFs

[Norton, Mike]

What I’m failing to understand is... if I set the CUBE’s default route to be my router on my network, then how will CUBE be able to reach the SIP provider’s call servers on the SIP provider’s network? It seems like I will need a routing protocol on whichever side of the CUBE doesn’t get a default route. Is that a normal requirement?

Just to back up a bit, I have been assuming CUBE would have two interfaces – one on my network, one on the SIP provider’s network. I’ve always assumed that this was the normal way of deploying CUBE but maybe I’m off base there and getting myself confused.

Only one voice vrf can be defined in IOS. Global under voice service voip.

Cube-SP lets you do multiple vrf's but is EoL and way different configuration.

If you plop a cube off your router and router interface is in a vrf and your separate cube is on that network then it should be fine as the cube is just a host then .... with default route to router.

Doesn’t have to be two VRFs, could be one VRF and the global route table, if that makes a difference. This idea is no connectivity between them, other than the application-layer connectivity provided by CUBE. This is hypothetical – I’m just trying to understand how/if this would work. I’m looking to plop a CUBE between my network and a SIP provider’s network without having to participate in routing protocol on either side.

You have two VRFs, do they have connectivity between them?

Can CUBE sit across two separate VRFs? I’ve never used it, but I’m envisioning an ISR having a VRF-Lite with default route pointed at my network, and a VRF-Lite with default route pointed at the SIP provider’s network. I’m thinking this would be the preferred way to do it, but maybe I’m missing something?

My Googling is dredging up a lot of really old info that I’m not sure is still relevant.
