Q
How do I configure VPN services on MSCG?
A
To configure VPN: 1. Define IKE and IPsec policies 2. Create tunnel interfaces 3. Bind interfaces to VPN instances 4. Apply ACLs and route-policies to tunnels.
Q
How does MSCG integrate with SD-N and SD-WAN architectures?
A
MSCG supports SDN via OpenFlow, BGP-EVPN, and Netconf/YANG APIs. It integrates with SD-WAN controllers for centralized policy, dynamic path selection, and service chaining.
Q
