Redistribution of RIB Routes into LISP
Example: Redistribution of RIB Routes in LISP
Figure 26: Redistribution of RIB Routes in a LISP Topology
In the above image, xTR1 is provides global access to a local OSPF stub network and xTR2 connects to an
external BGP cloud.
The following example shows a combined use of the two available route-import applications (database and
map-cache) in a LISP overlay fabric network. It first describes how prefixes from the OSPF cloud are imported
in xTR1 as database-mappings, and registered with the LISP mapping system, and then shows how the same
prefixes are imported as map-caches on xTR2 so that data traffic follows the optimized LISP overlay path.
Configuring Route Import with the Database Application
This section describes the database application configurations and commands to verify the configurations. In
this case, xTR1 redistributes prefixes from the OSPF network as database-mappings that are then registered
with the Mapping System. The figure Redistribute RIB Routes into Database Topology shows the devices for
configuring the LISP route import feature for the database application.
