- We've been tearing out my hair trying to figure out how to link 2 RSPF
- routers that use an IP Router to communicate. It seems like RSPF should
- work and NOT require that every station in the network Run RSPF, but we
- just can't figure out how to make it work.
-
- We've got:
-
- -------- -------- --------
- kf5mg <---440---> wb5tey <---144---> k5rw
- -------- -------- --------
-
- kf5mg and k5rw are running RSPF. When either one sends out it's RSPF
- broadcast, the other station can't hear it because they're on separate
- networks. Is there an easy way to fix this?
-
- We've set up and AXIP link between the two RSPF routers and set up the
- routes between k5rw and kf5mg to use wb5tey. Now they can hear each others
- RSPF broadcast, but the RSPF added routes are screwed up. All of k5rw's
- RSPF added routes on kf5mg show that they route through k5rw on 440 instead
- of wb5tey. All of kf5mg's RSPF added routes on k5rw show that they route
- through kf5mg on 144 instead of wb5tey. I'm guessing that the reason the
- routes are screwed up is that RSPF assumes that since it can 'hear' the
- station direct ( because of the axip link ) the RSPF added routes assume
- that they go direct to the remote system and don't take into account any
- pre-existing routes set up between the two RSPF routers.
-
- Next, we set up an ENCAP link in hopes that if the AXIP link was run
- over the ENCAP link the RSPF added links would use the ENCAP link routes.
- That didn't work either. The AXIP stuff goes over the ENCAP route, but
- the RSPF added routes still ignore the IP router that's in between the two
- RSPF routers.
-
- Someone is probably going to suggest that wb5tey ( in our example ) run
- RSPF. Yes... that will work, but I want/need to figure out this problem.
- Once we get this working, we'll add RSPF to both of our Internet Gateways.
- There's no way to get the network routers between the two gateways to run
- RSPF.
-
- Anyway.... either there is something basic that I'm missing or RSPF is
- really un-usable in a standard network and I can't see how one can really
- be using it. Any info/help/suggestions ( preferably working ) would be
- appreciated. Thanks.

-
- Not an easy way...
-
- This would have been solved fairly easily had RSPF2.2 been implemented.
- RSPF2.2 is a spec that makes clear that "normal" IP rules of "subnets"
- do NOT apply, and therefore you can create adjacencies using any kind
- of lower-layer (subnetwork in the OSIRM sense) connection and RSPF will
- use them if appropriate. But the code in NOS does not override IP's
- routing function, and treats RSPF node groups as IP subnets, which
- they ain't. I don't know what hackery has been done recently to allow
- faking things, but it's all half-way.
-
- Note that RSPF was designed to run on routers, but not be needed on
- end stations. Your example is of course the opposite, and tries to
- use intellgent end systems to get past a lack of intelligent routers.
- Perfectly sensible but since I don't personally _use_ any of the RSPF
- variants currently implemented, I can't tell you what works.
-
- If somebody would take the 2.2 spec and really implement it... Naaah,
- we're hams. Why do it right when a quick and dirty early hack is
- available? Why should routing be different from the "202" modems? :-(
