Gentlemen ,
We now have a working SRB config .Basically IP
routing was enabled on R5 and had to be turned off . Its always the small
details that are overlooked ....
:-)
Thanks to everyone who replied and helped ...Really appreciate it ... Don't
know what I would do without this list ..

>>R1 -------- R5 ----------- R2

>>R1 is a router having Token ring interface IP 10.1.1.1

>>R2 is a router having a Token ring Interface IP 10.1.1.2

>>R5 is the SRB router with NO IP routing or IP addresses ..
