Not adding the bandwidth command would let the EIGRP use the default interface bandwidth. However, this is not a problem is usually you have one link to same site. When you have multiple routes to certain sites you usually use the bandwidth to affect the routing decision of the EIGRP.
For example if you have a main site connected to a branch site using to Serial links will lead the EIGRP to load-balance over the two links. However, your serial maybe of different bandwidth for example one with 64Kbps and the other is 2Mbps. To affect the EIGRP routing decision you can issue the command bandiwdth 2000 on the Serial and then EIGRP will install one route to the branch office.
All other protocols behave the same however, OSPF also base it's metric on other values like delay and reliability etc...
"To affect the EIGRP routing decision you can issue the command bandiwdth 2000 on the Serial and then EIGRP will install one route to the branch office."
In general, we prefer that you set the bandwidth to what the bandwidth really is, as much as possible, and use delay to traffic engineer. This is because EIGRP also determines how fast to send packets on links under T1 in speed.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
