I am working for a design for customer with a Master Controller as a virtual router. Because the master controller is virtual there are some limitiations. The Master Controller will be in a differen VLAN 20 (10.20.0.0/24) the Border Router are in VLAN 30 (10.30.0.0/24). When I am looking at IWAN deploy guides the MC HUB and Border Router are directly connected.
Lo0: 10.1.0.11 Lo0: 10.1.0.5
MC HUB (1000v)-10.20.0.11-------- .1 Router between .1--------10.30.0.5-Border Router
I am planning to use Lo0 as source interface for the IWAN domain and I would care about the connectivity between the Lo0 interfaces for example with ospf area 0.
Is this a common deployment? Is there anything to consider about?
Many thanks and best regards
Hub or transit site MC may be placed in any place of your site topology.
Branch MC must be on a connected subnet with all local branch BRs (due to CSCuu40241 - known limitation). This is typically not an problem, as best practice dictates to have a direct L3 link between two boxes.
Thanks for your answer!
My Master Controller has connectivity to the local HUB-BR Router where PFR is configured and also to the Branch BR/Master Router.
From the Output of my MC-Router I see the connection but I do NOT see anything under configured interfaces!?

Does anybody know what could be the reason or had a similiar problem?
Many Thanks and best Regards
