LISP Efficient Multi-Homing with NJEDge.Net
LISP provides a streamlined solution for handling multi-provider connectivity and policy without BGP complexity.
- Multi-homing across different providers
- No need for any new appliances and is included in Cisco IOS (in most cases).
- However if your router does not have the software feature, it can be downloaded from CCO
- In some rare cases a license key may also be needed
The traditional IP addressing model associates both Location and Identity to a single IP address space, making mobility a very cumbersome process since identity and location are tightly bundled together. Because LISP creates two separate name spaces, separating IP addresses into Route Locators (RLOC) and End-point Identifiers (EID), and provides a dynamic mapping mechanism between these two address families, EIDs can be found at different RLOCs based on the EID-RLOC mappings. RLOCs remain associated with the topology and are reachable by traditional routing. However, EIDs can change locations dynamically and are reachable via different RLOCs, depending on where an EID attaches to the network.
Cisco Locator/ID Separation Protocol (LISP) is routing architecture that provides new semantics for IP addressing. The current IP routing and addressing architecture uses a single numbering space, the IP address, to express two pieces of information:
- Device identity
- Device attachment to the network
The LISP routing architecture design separates the device identity, or endpoint identifier (EID), from its location, or routing locator (RLOC), into two different numbering spaces. Splitting EID and RLOC functions yields several advantages.
LISP enables simplification in routing operation because it enables enterprises and service providers to pare down multi-homed routing while facilitating and improves scalability to any-to-any WAN connectivity. It supports data virtual machine mobility.
LISP routing architecture also:
- Improves scalability of the routing system through greater aggregation of RLOCs
- Optimizes IP routing for both IPv4 and IPv6 hosts
- Reduces operational complexities
LISP can be gradually introduced into an existing IP network without affecting the network endpoints or hosts.
