The value of the object vRtrIfVasIfType specifies whether this is a VAS access-facing interface (for ESM/AA this means sub-facing interface). It allows to skip over egress PBR for after-VAS traffic and allows to skip over AA divert when AA is deployed. none (0): Used when this interface is not a VAS access facing interface. This value is the default value. toFromAccess (1): Used when two separate toFromAccess and toFromNetwork interfaces are used for Value Added Service (VAS) connectivity. For VAS chaining: traffic arriving from access interfaces (like from a subscriber) is redirected to a PBR target reachable over this interface for upstream VAS processing; and downstream traffic after VAS processing must arrive on this interface, so the traffic is subject to regular routing but is not subject to AA divert, nor egress subscriber PBR. toFromNetwork (2): Used when two separate (toFromAccess and toFromNetwork) interfaces are used for Value Added Service (VAS) connectivity. For VAS chaining: traffic arriving from network interfaces (like destined to a subscriber) is redirected to a PBR target reachable over this interface for downstream VAS processing; and upstream traffic after VAS processing should arrive on this interface, so regular routing can be applied. toFromBoth (3): Used when single interface is used for Value Added Service (VAS) connectivity. For VAS chaining: both traffic arriving from access and network is redirected to a PBR target reachable over this interface for upstream/downstream VAS processing; and downstream traffic after VAS processing must arrive on this interface, so the traffic is subject to regular routing but is not subject to AA divert, nor egress subscriber PBR.
