Title: DECbrouter90 V9.14/V10.x example running DECnet Phase IV over X.25 PVCs

Product: DECbrouter90 V9.14/V10.x

Question: How do I configure the DECbrouter90 to route DEcnet PhaseIV over X.25
          PVC's?

Solution:

Here are the commands required to configure two DECbrouter 90's for routing 
DECnet PhaseIV over X.25 PVCs.

DECbrouter A                                    DECbrouter B

! Map the router's DECnet addresses to each other's X.121 addresses.
! The "broadcast" option enables dynamic routing protocol exchange.

! The pvc circuit number, 1 in this case, must be less than the virtual circuits
! assigned to the switched virtual circuits (SVCs), which have been defined
! above using the X25 htc and X25 ltc commands.
!
! Point to the protocol addres of the host at the other end of the PVC.
