Be a loving person rather than in a love relationship because relationships happen one day and disappear another day. They are flowers; in the morning they bloom, by the evening they are gone. But people find it very difficult to be a loving person, a loving soul, so they create a relationship and be fool that way that "Now I am a loving person because I am in a relationship". And the relationship may be just one of monopoly, possessiveness and exclusiveness. The relationship is needed only because love is not there. Relationship is a substitute. Become alert! Relationship destroys love, destroys the very possibility of its birth.

Router-on-a-stick is a term frequently used to describe a
setup up that consists of a router and switch connected using one Ethernet link
configured as an 802.1q trunk link. In this setup, the switch is configured
with multiple VLANs and the router performs all routing between the different
networks/VLANs. It's a very popular term and commonly used in networks where no
layer-3 switch exists.
Inter-vlan using router on a stick method.

Description: Open Shortest Path First (OSPF) is a link-state routing protocol for Internet Protocol (IP)
networks. It uses a link state routing algorithm
and falls into the group of interior routing protocols, operating within a
single autonomous system (AS). Using OSPF, a host that obtains a change to a
routing table or detects a change in the network immediately multicasts
the information to all other hosts
in the network so that all will have the same routing table information. Unlike
the RIP in which the entire routing table is sent, the host using OSPF sends
only the part that has changed. With RIP, the routing table is sent to a
neighbour host every 30 seconds. OSPF multicasts the updated information only
when a change has taken place.
Solution:
The given topology is:
Inter-Communication through OSPF.
