LISP Host-Mobility
Needs:
• Global IP-Mobility across subnets
• Optimized routing across extended subnet sites
LISP Solution:
• Automated move detection on XTRs
• Dynamically update EID-to-RLOC mappings
• Traffic Redirection on ITRs or PITRs
Benefits:
• Direct Path (no triangulation)
• Connections maintained across move
• No routing re-convergence
• No DNS updates required
• Transparent to the hosts
• Global Scalability (cloud bursting)
• IPv4/IPv6 Support

LISP Host-Mobility – Traffic Redirection Update Location Mappings for the Host System Wide
• When a host move is detected, updates are triggered: The host-to-location mapping in the Database is updated to reflect the new location
The old ETR is notified of the move
ITRs are notified to update their Map-caches
• Ingress routers (ITRs or PITRs) now send traffic to the new location

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

Null0 host routes indicate the host is “away”
Refreshing the Map Caches 1. ITRs and PITRs with cached mappings continue to
send traffic to the old locators 1. The old xTR knows the host has moved (Null0 route)
2. Old xTR sends Solicit Map Request (SMR) messages to any encapsulators sending traffic to the moved host
3. The ITR then initiates a new map request process
4. An updated map-reply is issued from the new location
5. The ITR Map Cache is updated
• Traffic is now re-directed
• SMRs are an important integrity measure to avoid unsolicited map responses and spoofing

Ingress Routing Challenge in DCI Extending Subnets Creates a Routing Challenge
• A subnet traditionally implies location
• Yet we use LAN extensions to stretch subnets across locations
Location semantics of subnets are lost
• Traditional routing relies on the location semantics of the subnet
Can’t tell if a server is at the East or West location of the subnet
• More granular (host level) information is required
LISP provides host level location semantics

Refreshing the Map Caches
1. ITRs and PITRs with cached mappings continue to send traffic to the old locators
1.The old xTR knows the host has moved (Null0 route)
2. Old xTR sends Solicit Map Request (SMR) messages to any encapsulators sending traffic to the moved host
3. The ITR then initiates a new map request process
4. An updated map-reply is issued from the new location
5. The ITR Map Cache is updated
• Traffic is now re-directed
• SMRs are an important integrity measure to avoid unsolicited map responses and spoofing West-DC East-DC

LISP Multi-Tenancy High Level View
Needs: • Integrated Segmentation • Ease of operations • Global Scale and interoperability
LISP Solution:
• Traffic (control & data) is “colored” (tagged) with an instance-ID • Mappings are also “colored” in DB and caches • On xTRs use VRFs as map cache contexts
Benefits: • Very high scale tenant segmentation
• Distributed/on-demand/no-adjacencies • Global mobility + high scale segmentation integrated in a
single IP solution • IP based solution, transport independent • No Inter-AS complexity • Overlay solution is transparent to the core

Summary and Conclusions
• LISP provides an effective solution for host mobility
• Some applications may require LAN extensions in combination with host mobility
