Description (partial)

In cases where `no ip redirects` was configured on an interface, the addition and removal of a secondary IP address will silently remove the `no ip redirects` command without warning. This is suboptimal in situations that require or is a bad practice to have redirects turned off.

The following sequence of commands will result in the issue being seen. By the last command the switch will have silently removed the `no ip redirects` command originally entered and mean that the switch is now not consistent with the original configuration. 

int vlan 1701
  ip address
  no ip redirects 
show run int vlan 1701
ip address secondary 
  no ip address secondary 
show run int vlan 1701
