Locator/ID Separation Protocol – LISP Part 1

Locator/ID Separation Protocol – LISP

The Locator/ID Separation Protocol (LISP) is a network architecture that implements the use of two namespaces instead of a single IP address. These namespaces, known as endpoint identifiers (EIDs), are assigned to end-hosts and routing locators (RLOCs), which are assigned to devices (primarily routers) that make up the global routing system. LISP is documented in RFC6830.

Separating Location and Identity provide a clear separation at the Network Layer between what we are looking for vs. how best to get there.

Network Layer Identifier – WHO you are in the network
Network Layer Locator – WHERE you are in the network
WHERE you are can change!
WHO you are should be the same!

LISP changes the routing architecture to implement a level of indirection between a hosts IDENTITY and its LOCATION in the network.

Control Plane – Map end point identities to their current location.
Data Plane – Encapsulates EID-addressed packets inside RLOC-addressed headers.

Traditional routing protocols uses a “PUSH” model to build a topology from the information gathered from the routing protocol, compute and install best route entries, and then advertise this information to neighbors. This information is pushed to all the neighbors in the routing domain without each neighbor actually requesting the routing information.

LISP uses a “PULL” model. If a router need to make a forwarding decision, it will ask the mapping database for the RLOCs associated with the destination EID prefix. The database responds with the EIDs to RLOCs mapping and the router caches it and send the packet towards RLOC to reach the EID prefix. It resembles the architecture employed by DNS. Once the information is cached and programmed into the forwarding table, the router will perform normal packet forwarding for subsequent packets being forwarded to that same destination. In order words, the router requests the forwarding information it needs, instead of being given all of the routing information implicitly.

LISP is an encapsulation/tunneling technology used to build overlays, it can use any underlying transport, as long as there is IPv4/IPv6 reachability in the underlay. This is accomplished in our network as the SP core is running BGP with each site. Note that this “underlay” is what is referred to as the RLOC space – the global BGP table. Like GRE or other tunneling techniques, we can tunnel one address-family over another. LISP uses a simple header, consisting of the outer IPv4/IPv6 header (RLOC source/destination), and a UDP + LISP header. For user data-traffic being encapsulated, LISP uses a destination UDP port of 4341. For the control-plane messaging between LISP nodes, UDP port 4342 is used. From an MTU perspective, LISP adds 36 Bytes of overhead for IPv4 (20 for IPv4 header, 8 for UDP, 8 for LISP), and 56 Bytes for IPv6.

Use Cases

LISP Deployment Models
Private Model
  • Private LISP deployment supports single enterprise
  • LISP Enterprise deploys:
    • xTRs
    • Mapping Systems
    • Proxy System, if required
Public Model
  • Public LISP deployment supports the need of multiple enterprises
  • LISP service provider deploys ‘shared’ Mapping System and Proxy System
  • LISP Enterprises subscribe to LISP SP, and deploy their own xTRs
Main Attributes of LISP

Ingress Tunnel Router (iTR) – An iTR is a router that resides in a LISP site.  Packets sent by sources inside of the LISP site to destinations outside of the site are candidates for encapsulation by the iTR. An iTR is also in charge of querying the mapping database when trying to make a forwarding decision. The query is sent to the Map Resolver using a Map-Request message.

Egress Tunnel Router (eTR) – An eTR is a router that accepts an IP packet where the destination address in the “outer” IP header is one of its own RLOCs.  The router strips the “outer” header and forwards the packet based on the next IP header found. This device is in charge of receiving LISP encapsulated packets from the underlay network, decapsulating them, and forwarding them towards the final destination inside the site.

xTR – Usually iTR and eTR functions are collocated on the same router, that router is called xTR.

Endpoint ID (EID) – An EID is a 32-bit (for IPv4) or 128-bit (for IPv6) value, typically an IP address allocated to End hosts at a site. EIDs MUST NOT be used as LISP RLOCs.

EID Prefix – EID prefixes are block of EIDs allocated to a site.

Routing Locator (RLOC) – An RLOC is an IPv4 or IPv6 address of an Egress Tunnel Router (eTR).  An RLOC is the output of an EID-to-RLOC mapping lookup.  An EID maps to one or more RLOCs. This address is routed in the global routing and must be reachable from other LISP site’s eTRs.

Proxy-iTR (PiTR) – A PiTR acts like an iTR but does so on behalf of non-LISP sites that send packets to destinations at LISP sites. A PiTR is defined in RFC6832.

Proxy-eTR (PeTR) – A PeTR acts like an eTR but does so on behalf of LISP sites that send packets to destinations at non-LISP sites. A PeTR is defined in RFC6832.

Proxy-xTR – A router performing both functions PiTR and PeTR is called a PxTR.

Map Server (MS) – Map Server holds all of the EID to RLOC mappings for all of the sites it is responsible for. The Map Server takes registrations from eTR routers via Map-Register messages.

Map Resolver (MR)This device is queried by the iTRs using Map-Request messages. The queries consist of iTRs asking for the mapping between EID and RLOC.

LISP Router – A LISP router is a router that performs the functions of any or all of the following: iTR, eTR, Proxy-iTR (PiTR), or Proxy-eTR (PeTR).

We will use following network topology for LISP configuration.

 

Network Topology
  • R3, R4, R5, R6 are provider edge routers in SP network.
  • R7 is BGP Route-Reflector in SP network and R3, R4, R5,R6 are RR clients.
  • R7 is working as LISP MAP Resolver (MR) and MAP Server (MS).
  • R1 is working as xTR, performing both iTR and eTR functions, in LISP Site-A.
  • R1 is running dual stack, both IPv4 and IPv6, connected to LAN router R8.
  • R1 is registered with LISP MAP Server, EIDs (IPv4 – 8.8.0.0/16, IPv6 – 2001:8:8::/48) and RLOC addresses 13.13.13.1 (Weight 100) and 14.14.14.1 (Weight 50).
  • With above weight parameters, R1 is telling remote sites to send traffic for Site-A EIDs in ratio of 100:50 to RLOC addresses 13.13.13.1 and 14.14.14.1 respectively.
  • R2 is working as xTR, performing both iTR and eTR functions, in LISP Site-B.
  • R2 is running dual stack, both IPv4 and IPv6, connected to LAN router R9.
  • R2 is registered with LISP MAP Server, EIDs (IPv4 – 9.9.0.0/16, IPv6 – 2001:9:9::/48) and RLOC addresses 25.25.25.2 (Weight 100) and 26.26.26.2 (Weight 50).
  • With above weight parameters, R2 is telling remote sites to send traffic for Site-B EIDs in ratio of 100:50 to RLOC addresses 25.25.25.2 and 26.26.26.2 respectively.

At this moment, iTR router at both sites do not have information to reach each other’s EID prefixes.

An iTR is a router that resides in a LISP site.  Packets sent by sources inside of the LISP site to destinations outside of the site are candidates for encapsulation by the iTR. An iTR is also in charge of querying the mapping database when trying to make a forwarding decision. The query is sent to the Map Resolver using a Map-Request message.
