The cisco is whining that the BGP ident it's receiving is 10.10.24.2,
and is wrong. Is 10.10.24.2 the Juniper's lo0 or router-id or used
anywhere else in the network? The cisco should not care what the
identifier is, as long as it's unique. What does the Juniper's log
messages file say as well as traceoptions, that would give you even more
information.

Turn off the multihop stuff, not needed. The only time you usually see
multihop for IBGP is in a confederated setup if recursion is needed for
CEBGP.
