The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter contains the following sections:
This chapter describes how to configure the Multicast functionality in Locator/ID Separation Protocol (LISP) architecture where the Multicast source and Multicast receivers can reside in separate LISP sites.
LISP introduced a mapping function from a site's Endpoint ID (EID) prefix to its associated Routing Locator (RLOC). Unicast packets require the mapping of both the source and destination address. Multicast only requires the source address to be mapped as the destination group address is not topology-dependent.
When the Multicast LISP feature is enabled, a new tunnel interface type called GLT (Generic Lisp Tunnel) is created. The GLT is supported by Oracle Identity Manager APIs and only one GLT per Virtual Device Context (VDC) is created.
The LISP Multicast feature is not supported on the F3 series module.
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release.

The following restrictions apply to the LISP Multicast feature:
Perform this task to configure a device to support Locator/ID Separation Protocol (LISP) Multicast functionality.
In this task, a LISP site an edge router configured as an xTR (performs as both an ITR and an ETR) and includes a single IPv4 connection to an upstream provider. Both the RLOC and the EID are IPv4. Additionally, this LISP site registers to one map resolver/map server (MR/MS) device in the network core.
One map resolver/map server (MR/MS) system is assumed to be available for the LISP xTR to configure. The MR/MS have IPv4 RLOC 11.0.0.2.
Mapping services are assumed to be provided as part of this LISP solution via a private mapping system or as a public LISP mapping system. From the perspective of the configuration of these LISP site xTRs, there is no difference.
The steps in this task enable and configure LISP Multicast ITR and ETR (xTR) functionality when using a LISP map server and map resolver for mapping services.
Configuration Example for LISP Multicast
The following example shows how to configure Locator/ID Separation Protocol (LISP) Multicast on either the Egress Tunnel Router (ETR) or the Ingress Tunnel Router (ITR):
vrf context vrf1 ip pim rp-address 35.0.0.1 group-list 224.0.0.0/4 ip pim ssm range 232.0.0.0/8 ip lisp itr-etr <<< this router acts as a Lisp xTR gateway ip lisp database-mapping 20.0.0.0/24 11.0.0.1 priority 1 weight 100 lisp instance-id 1 ip lisp locator-vrf default ip lisp itr map-resolver 11.0.0.2 ip lisp etr map-server 11.0.0.2 key 3 5b0f2bd760fe4ce3 ip lisp multicast <<< this router supports Lisp Multicast
