Implementing Routing as a Service

1. Configure SPBV on all nodes within the SPB network as detailed in Shortest Path Bridging (SPB) Configuration
2. Identify all customer facing VLANs within the SPB network and assure that all nodes within the SPB network have access to those VLANs
3. Identify all nodes in the SPB network that are directly connected to customers that will be configured as SPB Helper routers
4. Configure all Helper Router VLAN interfaces with the same IP address per VLAN (for example: the VLAN 20 IP address on each Helper Router should be the same address)
5. Identify L3 routers with VLANs exterior to the SPB network that will be configured as Main routers
6. The Loopback address on both Main and Helper Routers should be unique
7. Configure static routes on each Main Router to the Loopback address of each Helper Router for each VLAN in the SPB network
8. Configure VRRP on all customer VLAN interfaces interior to the SPB network on each Main and Helper router, enabling the helper-router function on each Helper router VLAN interface
9. Configure a unique SPB router ID on each Main router
