1. /30 subnets for the PtP links to remote subnets
2. /29 and /28 subnets for the remote subnets themselves (6 and 14 hosts)
We'll want to route over the PtP POTS serial link to the users' remote
subnets.
The online HTML RADIUS manual (Oct 96) indicates I might specify the
user, PtP link, and PtP netmask like:
chris Password = UNIX
Service-Type = Framed-User,
Framed-Protocol = PPP,
Framed-IP-Address = 208.218.26.14,
Framed-IP-Netmask = 255.255.255.248,
Framed-Routing = Broadcast-Listen
Which would specify the remote end of the PtP as 208.218.26.14 with a
/30 subnet. This is for the PtP link only, not the remote subnet.
Is this correct? Does the Portmaster assign to its own end the
208.218.26.13 address from the same /30 subnet, automagically?
Now I need to tell the PM about the remote subnet. Again, the HTML
manual says:
The Framed-Route reply item adds a route to the PortMaster's routing
table when service to the user begins. Three pieces of information are
required; the destination IP address, gateway IP address, and
metric. An example is shown below.
bob Auth-Type = System
Service-Type = Framed-User,
Framed-Protocol = PPP,
Framed-IP-Address = 150.128.1.1,
Framed-Route = "150.128.1.0 150.128.1.1 1"
so I would think I could tell it about my remote subnet by adding a
line:
Framed-Route = "208.218.26.192 208.218.26.14 1"
specifying the first address in my remote /28 subnet.
Is this correct? How does it know my remote net is really a /28 and
not a /24 (Class C) as the manual's example implies?
The manual section on "Framed-Routing" talks about RIP, but RIP
doesn't understand subnets, let alone VLSMs like I'm trying to use
here. I also understand ComOS 3.5 supports OSPF, and I need that to do
VLSMs (I think).
I'm OSPF-challenged. Does Framed-Routing also turn on OSPF support? Has
Framed-Route been extended to support inclusion of a netmask size in
the specification, maybe like:
Framed-Route = "208.218.26.192/28 208.218.26.14 1"
Or is there a different way to do it?
Any help would be most appreciated. Thanks.
