PxTR 1 or RTR Configuration RTR Locator-Set Inheritance
Step 4 The configurations are relevant for RTR or PxTR 1. Similarly, configure the RTR or PxTR 2
device too.
PxTR 1 or RTR Configuration RTR Locator-Set Inheritance
An RTR locator set can be defined in the underlay VRF and can then be referenced in an overlay VRF.
Step 1 Configure LISP
(config)# feature lisp
Step 2 Create two VRF instances on the RTR, one for the underlay (VRF core), and one for the overlay
(VRF vrf5000).
Configure LISP parameters for the core VRF
(config)# vrf context core
Note The LISP locator set setCore is defined in the underlay VRF core and then associated using the lisp
map-request itr-rlocs command in the overlay VRF vrf5000.
Configure LISP parameters for the vrf5000 VRF
(config)# vrf context vrf5000
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.
