Does this work differently on a serial interface? On an fa int:

route-server1(config)#int lo75
route-server1(config-if)#ip address 208.70.109.155 255.255.255.255
route-server1(config-if)#ip address 208.70.109.156 255.255.255.255 sec
route-server1(config-if)#no ip address 208.70.109.155 255.255.255.255

Must delete secondary before deleting primary
