It does work, but it has nothing to do with the broadcast domain(s). Even thou
gh PC1 and PC2 are in the same broadcast domain, they think that they are in se
parate broadcast domains, because of the IP addresses. So they will send their
packets destined for each other to the router, which in turn sends them to the
receiving PC, even though it is on the same interface.
Unless the PCs are expecting proxy ARP to be on and are ARPing for each other's
addresses, they will bounce all of their data off the router. It works, but i
t's not a good situation.

I'd say yes because it is still one broadcast domain? I'm thinking more in
terms of VLANs set up on RSMs like as follows:
VLAN25
ip address 141.191.3.0 255.255.255.0
ip address 141.191.4.0 255.255.255.0 secondary
A PC with address 141.191.3.1 would be able to ping a PC with address
141.191.4.1. Am I correct?

Here it goes:
On an ethernet LAN segment, there are PC1, PC2, and Router.
PC1 is configured with IP address: 10.1.1.1/24
PC2 is configured with IP address: 10.1.2.2/24
Router's ethernet interface is configured with 2 IP addresses with
both subnets: 10.1.1.3/24 and 10.1.2.3/24,
Now, what if PC1 pings PC2, would it go through and why?
