Yes this is true, it uses ip precedence 6. I am not sure where to find
documentation on it but I recently put a sniffer on an Ethernet segment
between two routers running OSPF and BGP. Looking at the update packets
it indeed had ip precedence 6.

Thanks,

Subject: TOS reserved bits 6/7 and routing protocols

Hello all. I was recently told that some routing protocols (BGP) uses
the reserved TOS bit for routing protocol establishment and updates. I
could not find any documentation to support this. Does any one know if
this statement is correct, and if so where can I find documentation on
it? TIA. Bob
