Bridge-group operations

We have two core switches and both are configured pretty much alike but one has these bridge-group 1 commands and the other does not.

Bridging routes non-ip traffic between vlans?

How does this setup work?

Do bridge groups route between only the vlans configured with the bridge-group 1 command and can't go to other vlans?

The following is from 192.xxx.1.3

I notice the priorities are 90 on this swith are 90 and left at default on 192.xxx.1.2 so HSRP would prefer .3 (this switch) but wouldn't dlsw go down if .3 goes down?

dlsw local-peer peer-id 192.xxx.254.2 group 192 border promiscuous
dlsw load-balance round-robin
dlsw remote-peer 0 tcp 192.xxx.254.2
dlsw remote-peer 0 tcp 192.xxx.254.1
dlsw remote-peer 0 tcp 192.xxx.254.3
dlsw remote-peer 0 tcp 192.xxx.254.4
dlsw remote-peer 0 tcp 192.xxx.254.6
dlsw remote-peer 0 tcp 192.xxx.254.5
dlsw bridge-group 1
dlsw udp-disable
