Eigrp on E1 subinterface

[natsira]

Below a part of the configuration of my router:

router eigrp 56

passive-interface FastEthernet0/0

passive-interface Serial1/0:1

passive-interface Serial1/0:6

passive-interface Serial1/0:7

passive-interface Serial1/0:11

network 172.16.0.0 0.0.255.255

no auto-summary

And here the result of debug eigrp packets hello:

Router#

4w6d: AS 56, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0

Router#ter no monitor

I would like to know why my router nevertheless sends hello paquets on the interfaces which are supposed being passive (serial 1/0:1 and 1/0:7).

Thanks

Interesting. Could be CSCec42182, but that's marked as unreproducible, or CSCeb87286, but that only relates to virtual access interfaces. Can you open a TAC case?
