Hi All,

Is it possible to include a loopback address on a router when one is not
specified or requested and use it in BGP in the update-source command without
being penalised? I know that this is recommended in the real world so must be
reflected in the lab - I hope. Also, when defining OSPF areas is it more
acceptable to stipulate the exact interface address or its subnet e.g
192.168.1.1/24 on s0 - can this be 'network 192.168.1.1 0.0.0.0 area 0' or
'192.168.1.0 0.0.0.255 area 0' - which is preferred in the lab again if a
preference is not stated?

Thanks,

Carl
