The Path Vector Routing Protocol specification
            
        
there are some captures of
                the protocol:
                ipv4 capture
                ipv6
                    capture
            
            
        
there are some text decodes
                of the protocol:
                ipv4 decode
                ipv6
                    decode
            
            
        
            
        
here is a specification
                about it:
                pvrp
                    specification by J. Sreenan
            
        
this is a clear text
                protocol.
            
            
        
the prefix descriptor have
                the following
                parameters:
                -prefix=<addr>/<len>
                -label=<num>
                -metric=<num>
                -tag=<num>
                -path=<rtrid>
                [rtrid]...
                
                there are these types
                of messages:
                -open rtrid=<addr> name=<text>
                -reachable
                <prefix>
                -withdraw <prefix>
                -startEncrypt
                <proto>
                -password-request
                <base64channenge>
                -password-reply <base64response>
                -error
                <text>
                -warning <text>
                -discard <text>
                -echo
                <text>

                -close
