LISP Overview
LISP Overview
• Original Motivation…
• An IP address “overloads” location and
identity
– Today… “addressing follows topology”
– Efficient aggregation is only available for Provider
Assigned (PA) addresses
– Ingress Traffic Engineering usually requires Provider
Independent (PI) addresses and the injection of “more
specifics” :: this limits route aggregation compactness
– IPv6 does not fix this
• Route scaling issues drive system costs
higher
– Forwarding plane (FIB) requires expensive memory
– Route scaling “drivers” are also seen in Data Centers
and for Mobility :: not just the Internet DFZ

LISP Overview
• Identity and Location :: an Overloaded Concept in Routing Today…
• Let’s scale the ID address
databases to 1010 and allow it
to hold any prefix length
(e.g. /32)
• Let’s provide a mechanism to
provide on-the-fly resolution
of ID and locator
• High scale
design, and ability
Enterprise
to change locator for fixed ID
enables Mobility!

LISP Overview
• LISP :: A Routing Architecture – Not a Feature
LISP changes the routing architecture to implement a level of indirection
between a hosts IDENTITY and its LOCATION in the network
LISP changes the current ROUTING Architecture
• Changes lead to DISRUPTION
• Disruption leads to OPPORTUNITIES
• LISP allows both SPs and Enterprises to do remarkably different
things than allowed by traditional approaches
• LISP enables NEW services (VPNs, IPv6, Mobility, “cloud”) in one,
common, simple architecture

LISP Overview
• LISP :: A Routing Architecture – Not a Feature
 Uses pull vs. push routing
 LISP use-cases are complimentary
‒ OSPF and BGP are push models; routing
stored in the forwarding plane
‒ Simplified multi-homing with Ingress traffic
Engineering; no need for BGP
‒ LISP is a pull model; Analogous to DNS;
massively scalable
‒ Address Family agnostic support
 An over-the-top technology
‒ End-host mobility without renumbering
‒ Address Family agnostic
 Enables IP Number Portability
‒ Incrementally deployable
‒ End systems can be unaware of LISP
 Deployment simplicity
‒ No DNS changes; “name == EID” binding
 An Open Standard
‒ Minimal CPE changes
‒ Some new core infrastructure components
© 2014 Cisco and/or its affiliates. All rights reserved.
‒ Never change host IP’s; No renumbering costs
‒ Session survivability
‒ No host changes

‒ Virtualization support

A: It can… But preparation limits issues…
‒ Encapsulation overhead is 36B IPv4 and 56B IPv6
‒ LISP supports “stateful” (PMTUD) and “stateless”
(fragmentation) options
‒ Tunnel/MTU issues are well known (GRE, IPsec, etc.)
and are usually operationally tractable

Scaling the LISP Mapping System
‒ Deploy multiple “stand-alone” Map-Servers” and register each
LISP Site to all of them (up to eight)
‒ Deploy Map-Resolvers in an “Anycast” manner
‒ Or, deploy a “hierarchical” Mapping System - DDT

• LISP Internetworking :: Day-One Incremental Deployment
 Early Recognition
‒ Up-front recognition of an incremental deployment plan
‒ LISP will not be widely deployed day-one
 Interworking for:
‒ LISP-sites to non-LISP sites (e.g. the rest of the Internet)
‒ non-LISP sites to LISP-sites
 Proxy-ITR/Proxy-ETR are deployed today
‒ Infrastructure LISP network entity
‒ Creates a monetized service opportunity for infrastructure players

LISP Data Center/Host Mobility
• Data Center/Host Mobility – Overview

Needs:
‒ VM-Mobility extending subnets and across subnets
‒ Move detection, dynamic EID-to-RLOC mappings,
traffic redirection

LISP Solution:
‒ OTV + LISP for VM-moves in extended subnets

VM
a.b.c.1
‒ VM OS agnostic, seamless, integrated, global
workload mobility
‒ Direct Path (no triangulation)
‒ Connections survive across moves
‒ No routing re-convergence, no DNS updates
‒ Global Scalability (cloud bursting)
‒ ARP elimination

LISP Host-Mobility – First Hop Routing
• No LAN Extension
• SVI (Interface VLAN x) and HSRP configured as usual
– Consistent GWY-MAC configured across all dynamic subnets
• The lisp mobility <dyn-eid-map> command enables proxy-arp functionality on the SVI
– The LISP-VM router services first hop routing requests for both local and roaming subnets
• Moving hosts always talk to a local gateway with the same MAC
