1841.0. "hub900/brouter90 bridged point to point" by SCCAT::SHERRILL () Wed Jan 04 1995 17:26

    
    Is there any problem with a DECbrouter 90 in a DEChub 900 being used
    as just a bridge to a WAN? What we are trying to accomplish is one
    single 56k connection to a customers home without useing an ip subnet.
    Since this will be a single point to point bridged connection is
    there any problem with turning spanning tree off and does Cisco
    software support this?? The config would be a DECbrouter 90 in
    a DEChub900 connected via the hub thinwire to the back ethernet
    port , Serial line to a dsu, a standalone Brouter 90 in the customers
    house with a DSU and then connected to a small lan in his home.

    Why turn off spanning tree?  It costs almost nothing.

    Shouldn't be a problem turning off spanning tree in this case.
    
    I've seen people turning off STP on remote links in order to not
    have disturbances on one side of a far link disrupt an extended LAN
    on the other.

    Thanks for the replys, it looks like this is the config we will go
    with.Tell me if my thinking is wrong  , the reason we want spanning
    tree off is we don't want the remote bridge to become the root bridge
    for this network as there are DECbridge 900's in the 4 hubs that are 
    in the main office.

    Make sure that you set the 90 to do IEEE bridging, not DEC bridging.

    	See note 271 in the DECbrouter90 conference, KALI::DEWBR. Spanning
    tree is *not* disable-able on the DECbrouter90, but there is a way to
    create separate, non-communicating 802.1d Spanning Tree domains.
