Operation 227
Multi-PoP network
In a multi-PoP network, the Auto Manage Routes feature allows to avoid a BGP v6 router under the
following conditions:
l
When the Layer 2 bridge is enabled (which implies that the BGP v6 router is not required for
managing data traffic).
l
When PoPs and E2E Controller are in the same subnet or L2 broadcast domain.
In a multi-PoP network, Deterministic Prefix Allocation (DPA) is used. The mesh gets divided into zones.
Each PoP is the best gateway to reach nodes in its zone. When a PoP is down, a different alive PoP must
be used as a gateway to reach zones. When the Auto Manage Routes feature is enabled, it performs the
following functions in a multi-PoP network:
l
Understands the network topology of 60 GHz cnWave,
l
Keeps a track of aliveness of PoPs, and
l
Dynamically builds and manages the routing table.
Figure 251 is an example of an IPv6 route table that is built automatically by the feature for a four PoP
network.

Figure 252 shows how the cnMaestro dashboard diagrammatically displays the routes taken by E2E
Controller and the traffic controlled by cnWave nodes.
