If cable is pulled and plugged back in when the machine is already up, I 
would be astonished if it didn't just come back.  In fact, I just tried 
it to be sure, and everything "just worked".

Vitalie, perhaps some info about the kind of NIC you have might help.  
Also can you show ifconfig
    1) before you pull the cable
    2) after you pull the cable
    3) after you plug the cable back in

At least then we could compare what happens for you with what happens 
for me.

For reference, I see:

Before:
sk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255
        inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255
        ether 00:11:d8:94:74:49
        media: Ethernet autoselect (1000baseTX <full-duplex,flag0,flag1>)
        status: active

Pulled:
sk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255
        inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255
        ether 00:11:d8:94:74:49
        media: Ethernet autoselect (none)
        status: no carrier

Back in:
sk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255
        inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255
        ether 00:11:d8:94:74:49
        media: Ethernet autoselect (1000baseTX <full-duplex,flag0,flag1>)
        status: active
