LISP Multicast

LISP Multicast

The LISP Multicast feature introduces support for carrying multicast traffic over a Locator ID Separation Protocol (LISP) overlay. This support currently allows for unicast transport of multicast traffic with head-end replication at the root ingress tunnel router (ITR) site. This allows network operators to use LISP to carry multicast traffic over core networks that do not have native multicast capabilities.

Finding Feature Information

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. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Prerequisites for LISP Multicast

  • You must configure basic LISP services on the device. Basic LISP configurations are covered in "Configuring Basic LISP" section of this configuration guide.

Restrictions for LISP Multicast

  • LISP multicast does not support IPv6 endpoint identifiers (EIDs) or IPv6 routing locators (RLOCs). Only IPv4 EIDs and IPv4 RLOCs are supported.

  • LISP multicast does not support Dense Mode or Bidirectional Protocol Independent Multicast (PIM). Only PIM-Sparse Mode (SM) and PIM Source Specific Multicast (SSM) modes are supported.

  • LISP multicast does not support group to Rendezvous Point (RP) mapping distribution mechanisms, Auto-RP and Bootstrap Router (BSR). Only static-RP configuration is supported.

  • LISP multicast does not support LISP Virtual Machine Mobility (VM-Mobility) deployment. That is, LISP multicast cannot be used as a data center interconnect (DCI) mechanism.

Information About LISP Multicast

The implementation of LISP multicast includes the following features:

  • Mapping of multicast source addresses as LISP endpoint identifierss (EIDs). (Destination group addresses are not topology dependent.)

  • Building the multicast distribution tree across LISP overlays.

  • Unicast head-end replication of multicast data packets from sources within a root ingress tunnel router (ITR) site to receiver egress tunnel routers (ETRs).

  • Support for ASM (Any Source Multicast) and SSM (Source Specific Multicast).

  • Support for various combinations of LISP and non-LISP capable source and receiver sites.

        Example: Configuring LISP Multicast in VRFs

        The following example shows how to enable and configure a simple LISP site with one IPv4 Routing locator (RLOC) and one IPv4 Endpoint identifier (EID) using xTR, a device which functions both as an Ingress tunnel router (ITR) and an Egress tunnel router (ETR), functionality and using a LISP map server and map resolver for mapping services:

        Device> enable
        Device# configure terminal
        Device(config)# vrf definition VRF1
        Device(config-vrf)# address-family ipv4
        Device(config-vrf-af)# exit
        Device(config-vrf)# exit
        Device(config)# ip multicast-routing vrf VRF1 [distributed]
        Device(config)# ip pim vrf VRF1 ssm range LIST1
        Device(config)# router lisp 22
        Device(config-router-lisp)# eid-table vrf VRF1 instance-id 10
        Device(config-router-lisp-eid-table)# database-mapping 198.51.100.0/24 192.0.2.10 priority 1 weight 100
        Device(config-router-lisp-eid-table)# exit
        Device(config-router-lisp)# ipv4 itr
        Device(config-router-lisp)# ipv4 etr
        Device(config-router-lisp)# ipv4 itr map-resolver 192.0.2.10
        Device(config-router-lisp)# ipv4 etr map-server 192.0.2.10 key 0 some-key
        Device(config-router-lisp)# exit
