eigrp named mode config shows delay in micro instead of pico

HI All,

  Need some help in figuring out what am i doing wrong with EIGRP named mode lab.I'm on Version 15.1(4)M7. I have enabled eigrp named mode and trying to figure out why the delay is in microeconds instead of pico

 

R1#show run | s eigrp                                
router eigrp MULTI-AF
 !
 address-family ipv4 unicast autonomous-system 100
  !
  topology base
  exit-af-topology
  network 150.1.0.0
  network 155.1.0.0
 exit-address-family

 

 

R1#show eigrp address-family ipv4 100 topology 150.1.2.2/32

    Hello,

    This is not a bug at all.  EIGRP "named mode" and "wide metrics" are two separate features of EIGRP.  Now, wide metrics are only supported in named mode but, it is entirely possible to have a version of IOS that supports EIGRP named mode but does not yet have the "wide metric" feature which now uses pico seconds instead of microseconds for the delay.

    Check out this document:  http://www.cisco.com/c/en/us/products/collateral/ios-nx-os-software/enhanced-interior-gateway-routing-protocol-eigrp/whitepaper_C11-720525.html

    It mentions how to check your EIGRP version that is running within your particular IOS version.  "show eigrp plugin" command.

    I do know that for traditional IOS, you need to be on about 15.4 version to get the wide metrics such as 1921 ISR router.  If you're running a 15.1 version on something like a 2811, you can do named mode but it does not yet support wide metrics and thus you will only see microseconds.

    good point; check plugins for eigrp. usually name mode = wide metrics

    Thanks, just keep in mind what you said is a VERY false assumption.
