This scenario verifies interoperability when the target ROUTER is attached to the model network.
IBGP speakers can't export a Routing Information. Therefore, to learn all Routing Information for IBGP speakers which must connect all "Full Mesh". So configure one IBGP Speaker as "Route Reflector*" and others as "Client" and check their action. * Route Reflector: Route Reflectors can export a Routing Information from other IBGP Speakers to Clients.
Verification Points : - IBGP speakers as Client learn disconnected other one's routing information. - Exchange of Routing Information from EBGP and IBGP between EBGP speakers.

Interoperability is checked using traceroute application program.
No Action Criteria Comments 1 Boot ROUTER-1. - - 2 Boot ROUTER-3. - - 3 Boot ROUTER-4. - - 4 Boot ROUTER-5. - Now ROUTER-3 and 5 learn the path between Net-x and Net-u. 5 Boot ROUTER-6. - Now ROUTER-4 and 6 learn the path between Net-x and Net-t. 6 Boot ROUTER-2. Check Routing Table of all routers. Now ROUTER-2 learns the path Net-z to Net-x, Net-u to Net-x and Net-t to Net-x and advertises all path to ROUTER-3 and 4. 7 Boot HOST-1. - - 8 Boot HOST-2. - - 9 Boot HOST-3. - - 10 At HOST-1, run "traceroute" to HOST-2's Global address.
