ROUTER 3
In order to route IP packets originating on Ethernet network 1.0.0.0 to a
destination on Ethernet network 4.0.0.0, Router 1 will on receipt of a
packet from the LAN addressed to network 4.0.0.0 examine its routing
tables. This should yield the information that Router 2 is the ''next hop''
router.
If an X.25 connection already exists to Router 2, the IP packet will simply
be sent down the existing SVC encapsulated in X.25 packet(s); otherwise a
