This is the deal, when you configure traditional bridging ie , SRB,TB etc
the moment you put an interface in a
bridge-group, all protocols that are not being routed are bridged.
Now, when you configure IRB or CRB, the moment you put an interface in a
bridge-group every protocol is
bridge. All protocols are passed on to the BVI interface in the case of
IRB. If you want to enable irb routing
use "bridge x route prototol" command. If you want to route on a
bridge-group interface disable bridging of that
protocol with " no bridge x bridge protocol" command.
DLSW+ is used for IBM non routable protocols so if you turn it on, it will
allow you to route all routable protocols as
usual and bridge all the IBM non routable protocols. You do not need to know
anything detailed about bridging staff.
I hope this helps
William

I remember reading on DOC CD somewhere and I have noted this
Bridging rules:
1. if the interface is config with Network address that protocol is routed
even if the TB/SRB is enabled on that i/f
2. Protocol will be bridged if the network address is not config and TB/SRB
is enabled
3. No routing or bridging on the interface, if neither protocol addres nor
TB/SRB is config for the interface.
I believe IP routing should not be stopped if u enable SRB on the TR i/f
with IP address.
any comments ?
