Hi: What are the effects of configuring the lo0 of the mapping agent in
an Auto-RP environment in sparse-dense-mode? Doyle's Vol. II on page 560
states that the loopback 0 intf. of the mapping agent "never must make
any sparse/dense determinations - meaning that the lo0 must only be in
sparse-mode. I tried with both and am not seeing any difference as far as
ro mappings go on the other routers. Is there anything else I can try to
check to see what breaks etc. Or anyone with a good explanation for the
above? Thank you. Mapping Agent output:Homburg-R4#sh ip pim rp mapping
