router rip network eth0 <--- is this correct? network 192.168.219.0/24 ##################################### JohnStanley Writes: Did you bother to check the documentation?
As always, yes I did, albeit the pdf version. Like much documentation, it is possibly a wonderful aide memoire for somebody who knows the subject intimately but it is a little terse and somewhat sparse for someone with no prior knowledge and little time.
The difficulty that I need to address is what ripd configuration provides rip info regarding 192.168.219.0/24 connected via eth1 out to all networks connected via 2xx.yyy.zzz.0/24 on eth0.
Must I configure a virtual IP from 192.168.219.0/24 on eth0 as well as eth1 or not? Do I just set ripd.conf to:
router rip network 192.168.219.0/24
Is that all that is required?
Recall that the purpose of this exercise is to simultaneously provide interim public and private ipv4 address connectivity on the same physical lan behind our Internet router. The long term objective is to remove the public address space from the lan. At that point this finessing becomes unnecessary.
For example:
INET Router: eth0 IP 2xx.yyy.bbb.64
eth1 IP 2xx.yyy.zzz.1 IP 192.168.71.1 ip 10.0.0.1
network 2xx.yyy.zzz.0/24 network 192.168.0.0/16 network 10.0.0.0/8
host1: eth0 IP 2xx.yyy.zzz.22
host2: eth0 IP 2xx.yyy.zzz.23 eth1 IP 192.168.219.1
host3: eth0 IP 192.168.219.102
host4: eth0 IP 192.168.71.65
INET Router <<-------->> SWITCH
host1/eth0 <<--------->> SWITCH
host2/eth0 <<--------->> SWITCH host2/eth1 <<--------->> HUB
host3/eth0 <<--------->> HUB
host4/eth0 <<--------->> SWITCH
How do I set up ripd on host2 so that host4 (192.168.71.65) reaches host3 (192.168.219.102) via host2 (2xx.yyy.zzz.23)? Clearly the ripd info for 192.168.219.0/24 must go out 216.185.71.23 but I am unclear as to what ripd.conf configuration settings accomplish this.
