Restrictions for LISP ESM Multihop Mobility

  • Supports Locator/ID Separation Protocol (LISP) multihop mobility only in Extended Subnet Mode (ESM) with Overlay Transport Virtualization (OTV).

  • Requires OTV First Hop Redundancy Protocol (FHRP) isolation to avoid hair-pinning of traffic across the OTV Data Center Interconnect (DCI) framework.

  • Does not support Network Address Translated (NAT’d) endpoint identifiers (EIDs).

Information About LISP ESM Multihop Mobility

LISP ESM Multihop Mobility Overview

A first-hop router (FHR) detects the presence of a dynamic host endpoint identifier (EID) and notifies the site gateway xTR. A device configured as both an ingress tunnel router (ITR) and an egress tunnel router (ETR) is known as an xTR. The site gateway xTR registers the dynamic EID with a map server. The Site Gateway xTR performs Locator/ID Separation Protocol (LISP) encapsulation/decapsulation of the traffic from or to the dynamic EID to or from remote sites.

Figure 1. LISP ESM Multihop Mobility Sample Topology



Multiple Layer 3 hops can exist between the FHR and the site gateway xTR when deploying the LISP ESM Multihop Mobility feature. You can insert non-LISP devices like firewalls and load-balancers into the data center.


Note
LISP supports silent host moves from the 15.4(1)T release.

Note
LISP supports redistributing host routes for servers discovered by LISP into Interior Gateway Protocol (IGP) via Open Shortest Path First (OSPF) protocol/ Intermediate System-to-Intermediate System (IS-IS) protocol/ Routing Information Protocol (RIP)/ Border Gateway Protocol (BGP).

Perform the tasks shown below to configure LISP ESM multihop mobility on a Locator ID/Separation Protocol (LISP) site with three IPv4 routing locators (RLOCs). In these tasks, a LISP site uses a single edge router configured as both an ITR and an ETR (known as an xTR) with two connections to the upstream provider. Both the RLOCs and the endpoint identifier (EID) prefix are IPv4. The LISP site registers to a map resolver map server (MRMS) device in the network core. The topology used in this LISP configuration is shown in the figure below.

Figure 2. Topology for LISP ESM Multihop Mobility



The components illustrated in the topology shown in the above figure are described below:

LISP Site
  • The customer premises equipment (CPE) functions as a LISP ITR and ETR (xTR).
  • The LISP xTR is authoritative for the IPv4 EID prefix of 10.1.0.0/16.
  • The LISP xTR has two RLOC connections to the core. The RLOC connection to xTR-1 is 172.18.3.3; the RLOC connection to xTR-2 is 172.19.4.4.

Mapping System
  • An MRMS system is assumed to be available for the LISP xTRs to configure. The MRMS has IPv4 RLOCs 10.1.1.0 and 10.1.1.9.
  • 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.

          Device(config)# router lisp
           

          Enters Locator ID/Separation Protocol (LISP) configuration mode.

           
          Step 4site site-name


          Example: 
          Device(config-router-lisp)# site EastWestDC
           

          Configures a LISP site and enters LISP site configuration mode on a LISP map server.

           
          Step 5authentication-key password


          Example: 
          Device(config-router-lisp-site)# authentication-key k
           

          Configures the password used to create the Hash-based Message Authentication Code (HMAC) Secure Hash Algorithm (SHA-1) hash for authenticating the map-register message sent by an egress tunnel router (ETR) when registering with the map server.

           
          Step 6eid-prefix eid-prefix accept-more-specifics


          Example: 
          Device(config-router-lisp-site)# eid-prefix 10.1.0.0/16 accept-more-specifics
           

          Configures a list of endpoint identifier (EID) prefixes that are allowed in a map-register message sent by an ETR when registering with the map server. Specifies that any EID prefix that is more specific than the EID prefix configured is accepted and tracked.

           
          Step 7exit


          Example: 
          Device(config-router-lisp-site)# exit
           

          Exits LISP site configuration mode and returns to LISP configuration mode.

           
          Step 8Repeat Step 4 to Step 7 to configure another LISP site.

          Example: 
          Device(config-router-lisp)# ipv4 map-server
           

          Configures a device to act as an IPv4 LISP map server.

           
          Step 10ipv4 map-resolver


          Example: 
          Device(config-router-lisp)# ipv4 map-resolver
           

          Configures a device to act as an IPv4 LISP map resolver.

           
          Step 11end


          Example: 
          Device(config-router-lisp)# end
           

          Exits LISP configuration mode and returns to privileged EXEC mode.
