Aside from the other "this is Redhat's code with which we're not
familiar" comments, I'd hazard a guess that the realservers (ie.
10.11.12.1 and 10.11.12.2) don't see their default gateway moving from
the old director (node) to the new, or there's an iptables setup on
either/both the master and backup nodes which blocks the traffic in,
out, or both.
Either way you may better off asking this question on the Piranha list:
https://www.redhat.com/mailman/listinfo/piranha-list
...although it's pretty quiet over there.
