Bug Description
Service chaining works on assumption that packets are routed in following scenarios,
1. Transparent Service-Chain
- Packets to and from left interface of service-instance
- Packets to and from right interface of service-instance
2. In-Network Service-Chain
- Packets to and from left interface of service-instance
- Packets to and from right interface of service-instance
3. In-Network Nat Service-Chain
- Packets to and from left interface of service-instance
To ensure packets transmitted from the interfaces given above, VRouter must implement unrestricted proxy-ARP on these interfaces.
Service-Instance interfaces have an attribute named “virtual-
Note:
In R3.2 and below VRouter relies on vrf-assignment rule on the interfaces for routing. Packets transmitted from service-interface go thru vrf-assignment rules and result in vrf-translation. Any packet that goes thru vrf-translation will always be routed by VRouter.
