Abstract
Aspects of the embodiments include receiving a packet at a network element of a packet-switched network; identifying a presence of a shared service destination address in a header of the packet; identifying a shared service destination address for the packet based, at least in part, on a destination internet protocol (IP) address stored in a forward information base; and forwarding the packet to the shared service destination address.
Claims20
A method comprising:
- receiving a packet at a network element of a packet-switched network;
- identifying a presence of a shared service destination in a header of the packet;
- identifying a shared service destination address for the packet based, at least in part, on a destination internet protocol (IP) address stored in a forward information base;
- and
- forwarding the packet to the shared service destination address.
2 more elements
A network element comprising
- an application specific integrated circuit (ASIC) comprising a forwarding information base (FIB);
- the FIB comprising:
- a tenant-specific region storing tenant-specific destination address information populated based on tenant-specific virtual forwarding and routing (VRF) instances;
- and
- a shared service region storing global shared service destination address information populated based on a shared service VRF, the shared service region comprising a next hop destination for a shared service network destination.
2 more elements
A data center fabric comprising:
- a network element configured to receive a packet from a tenant server, the network element comprising:
- an application specific integrated circuit (ASIC) comprising a forwarding information base (FIB);
- the FIB comprising:
- a tenant-specific region storing tenant-specific destination address information populated based on tenant-specific virtual forwarding and routing (VRF) instances;
- and
- a shared service region storing global shared service destination address information populated based on a shared service VRF, the shared service region comprising a next hop destination for a shared service network destination;
- and
- a shared services network element comprising a shared services server configured to:
- receive a packet;
- and
- determine whether to apply shared services to the packet based, at least in part, on an endpoint group tag located in the packet metadata.
