sh ip cef internal

[kim]

Hey guys

Hope you had a nice week so far... Maybe someone in here knows what the flags in the following output means, taken from a DMVPN lab setup:

R1# sh ip cef vrf nat 0.0.0.0/0 internal

0.0.0.0/0, epoch 3, flags rib only nolabel, rib defined all labels, RIB[B], refcount 7, per-destination sharing
  sources: RIB, D/N, DRH
  feature space:
   NetFlow: Origin AS 0, Peer AS 0, Mask Bits 0
   Broker: linked
   IPRM: 0x00018000 

 Specifically the D/N and DRH source flags? Where is a good source for information about the output from this command?

Cheers and thanks

/Kim

Hello @kim ,

can you provide a

show version

and the model of device you are using ?

if it is a multi layer switch the H flag should mean that forwarding happens in hardware in the TCAM Asic

Without more info it is difficult to get help

Hope to help
