Hi,

no, this messages appears only with no static RP configured. If i
configure a static RP
it disappears.

But thats not auto-rp with sparse-dense. From the CISCO docs,
http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cg/himc_c/chap05/mcbbasic.htm#wp1112026
 you don't have to configure "ip pim rp-address" on the Auto-RP. With
sparse-mode you configure a

"ip pim autorp listener".

This is needed. That's what i found in the documentation.
Useing c2600-i-mz.123-3.bin, c2600-ik9o3s3-mz.123-10a.bin and
c3640-ik9o3s-mz.124-7.bin only.
