Use the SET CIRCUIT command with the MAXIMUM ROUTERS parameter to set the maximum number of routers permitted on a particular Ethernet or FDDI circuit. The largest number of routers allowed on a LAN is 33, which is the default value of the MAXIMUM ROUTERS parameter. 

Interestingly enough, the DECnet network management architecture spec says the limit is 255.   33 is correct, actually; the reason is that an Ethernet router hello message contains a list of the other routers heard by this router, and the encoding of the packet limits the length of that list to 33 entries.
