Connectivity to internet via shared services in enterprise fabric based network with LISP control plane

A device comprising:

• a network interface in communication with a network;
• a processor configured to execute computer readable instructions included on a non-transitory memory;
• and
• a non-transitory memory including processor-readable instructions, that when executed by the processor, cause the device to:
• receive a request from a source host associated with the network to communicate with a destination host;
• determine whether the destination host is associated with the network;
• on a condition that the destination host is not associated with the network, determine an instance identifier (IID) and a proxy egress tunnel router (PETR) locator address used to communicate with the destination host;
• send an indicator to an ingress tunnel router (ITR) to encapsulate a packet with the IID and the PETR locator address before sending the packet from the source host to the destination host;
• and
• generate a policy as a function of the IID and the PETR locator address;
• send an unknown map reply (UMR) comprising the policy to the ITR.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by a computing device with a non-transitory memory and one or more processors, cause the computing device to perform or cause performance of:

• receiving a request from a source host associated with a network to communicate with a destination host;
• determining whether the destination host is associated with the network;
• on a condition that the destination host is not associated with the network, determining an instance identifier (IID) and a proxy egress tunnel router (PETR) locator address used to communicate with the destination host;
• sending an indicator to an ingress tunnel router (ITR) to encapsulate a packet with the IID before sending the packet from the source host to the destination host;
• and
• encoding the IID and the PETR locator address.
