Your routing tables look fine.

The only thing I see missing from that command is the /DYNAMIC switch.

Here's what I use to bring my SLIP line up (I spend a fair chunk of time
at the far end of a SLIP line)

$ Set NoOn
$ Verify = F$Verify(1)
$ If F$GetDVI("TTA3","NET") Then -
  MultiNet Set/Interface SL0/Down/VMS_Device=TTA3/Link_Level=SLIP
$ Allocate TTA3
$ Define/User SYS$INPUT SYS$COMMAND
$ Set Host/DTE/Command=_ TTA3:
$ MultiNet Set/Interface SL0/Address=134.24.10.123/Protocol=IP-
  /VMS_Device=TTA3/Link_Level=SLIP/IP_SubNet=255.255.255.0-
  /Point_To_Point_Dest=134.24.10.1/Dynamic/D1/D2
$ Exit 0*'F$Verify(Verify)' + 1


The /D1/D2 switches govern the use of header compression.  You probably
want to omit using them unless you know the gadget on the other end is
capable of doing header compression.

It's the preferred method, in fact.
