LISP Support for Disjointed RLOC Domains
(config)# vrf context core
• After configuring the LISP ITR and ETR functions on PxTR 1, the LISP Map-Resolver (used by the ITR
to send Map-Requests) and Map-Server (used by the ETR to register EIDs) locator addresses are
configured.
• Also, LISP multicast transport and LISP Virtual Extensible LAN (VXLAN) encapsulation functions are
enabled.
Configure LISP parameters for the vrf5000 VRF
(config)# vrf context vrf5000
The following configuration chunk is specific to connecting disjointed RLOC spaces.
• The lisp locator-set command specifies a locator set for RTR RLOCs. 192.0.2.10 and 192.0.2.21 are
the RLOCs connecting the RTR to each IPv4 locator space.
• The lisp map-request itr-rlocs command defines RTR RLOCs used in the Map-Request messages
generated by the RTR. You can enable multiple locator sets, but only one of them can be active at a point
in time, and that is determined by including the name in the lisp map-request itr-rlocs option.
• Since Map-Resolver and Map-Server addresses are enabled in VRF core, VRF core is referenced within
VRF vrf5000, in the locator-vrf core command.
Step 3 Configure an IP address for routing in the underlay
(config)# interface loopback0
The configured loopback interface IP address is used for IS-IS communication within the LISP site, and is
added to VRF core.
