Yesterday I moved routing of one subnet from a Bay Router over to an
RSM on a Cisco 5505. I used a secondary IP address, since they have no
VLANs set up yet, to provide connectivity for routing of both subnets
(192.168.25.0 and 192.168.24.0).
Here's the question, how long does split horizon stay in effect for
RIP version 2? After I moved the 192.168.24.0 network over to the RSM,
the network was not being propagated to the rest of the routers on
this customer's network. The problem was that 192.168.24.0 was
originally being advertised by the Bay (192.168.25.1). So the
interface on the RSM would not advertise the network even after it was
off the Bay because it had originally received it from another source.
Today, a full day later, the route still won't go out. So I disabled
split-horizon and now it works.
