	The OSPF routing changes as follows:
	Routes on OSPF_MAIN router:
	[admin@OSPF_MAIN] ip route> print
	Flags: X - disabled, I - invalid, D - dynamic, J - rejected,
	C - connect, S - static, r - rip, o - ospf, b - bgp
	#	DST-ADDRESS	G GATEWAY	DISTANCE INTERFACE
	0	Io 192.168.0.0/24		110
	1	DC 192.168.0.0/24	r 0.0.0.0	0	main_gw
	2	Do 10.3.0.0/24	r 10.2.0.1	110	to_peer_2
	3	Io 10.2.0.0/24	110
	4	DC 10.2.0.0/24	r 0.0.0.0	0	to_peer_2
	5	Io 10.1.0.0/24	110
	6	DC 10.1.0.0/24	r 0.0.0.0	0	to_peer_1
	On OSPF_peer_1:
	[admin@OSPF_peer_1] ip route> print
	Flags: X - disabled, I - invalid, D - dynamic, J - rejected,
	C - connect, S - static, r - rip, o - ospf, b - bgp
	#	DST-ADDRESS	G GATEWAY	DISTANCE INTERFACE
	0	Do 192.168.0.0/24	r 10.3.0.2	110	backup
	1	Io 192.168.0.0/24		110

	3	Do 10.2.0.0/24	r 10.3.0.2	110	backup
	4	Io 10.1.0.0/24	110
	5	DC 10.1.0.0/24	r 0.0.0.0	0	to_main
	On OSPF_peer_2:
	[admin@OSPF_peer_2] ip route> print
	Flags: X - disabled, I - invalid, D - dynamic, J - rejected,
	C - connect, S - static, r - rip, o - ospf, b - bgp
	#	DST-ADDRESS	G GATEWAY	DISTANCE INTERFACE
	0	Do 192.168.0.0/24	r 10.2.0.2	110	to_main

	3	Io 10.2.0.0/24	110
	4	DC 10.2.0.0/24	r 0.0.0.0	0	to_main
	5	Do 10.1.0.0/24	r 10.2.0.2	110	to_main

The change of the routing takes approximately 40 seconds (the hello-interval setting). If required, this setting can be adjusted, but it should be done on all routers within the OSPF area!
