On Routers, passive-interface settings are shared amongst ALL ADDRESS-FAMILIES, INCLUDING GLOBAL. While on the 3560/3750/6500 etc L3 Switch IOS, the address-families each have their own unique passive interface settings.

For instance:

router eigrp 1
 network 10.0.0.0
 no auto-summary
 passive-interface default
 !
 address-family ipv4 vrf VRF-A
  network 10.0.0.0
  no auto-summary
 exit-address-family
 !
 address-family ipv4 vrf VRF-B
  network 10.0.0.0
  no auto-summary
 exit-address-family
end

The above code snippet on a Cisco Router would cause no EIGRP neighbor relationships to form, in either VRF or the global route table. However, on a Cisco L3 switch, the passive-interface command would ONLY apply to the global route table and each VRF will not have any of its member interfaces be acting as passive.

This final code snippet is not valid on a Router IOS, but is perfectly valid(and desired) on a L3 Switch IOS, with Po1 in the global route table, Po2 in VRF-A, and Po3 in VRF-B:

router eigrp 1
 network 10.0.0.0
 no auto-summary
 passive-interface default
 no passive-interface Po1
 !
 address-family ipv4 vrf VRF-A
  network 10.0.0.0
  no auto-summary
  passive-interface default
  no passive-itnerface Po2
 exit-address-family
 !
 address-family ipv4 vrf VRF-B
  network 10.0.0.0
  no auto-summary
  passive-interface default
  no passive-interface Po3
 exit-address-family
end
