Each router will need two static routes. If these are Cisco IOS routers,
you can cut and paste the two lines that appear under "RouterX's statics
routes" to each of the respective routers. I tried this in the lab, so I
know it works. If you stare at it long enough, it makes some sense.
After pasting the routes, compare each router's routing table to this
message, they should be the same:
0/0 0/1
RouterA 10.2.3.1 10.5.4.1
RouterB 10.2.4.1 10.2.3.2
RouterC 10.6.2.1 10.2.4.2
RouterD 10.5.4.2 10.6.2.2<?xml:namespace prefix = o ns =
"urn:schemas-microsoft-com:office:office" />
(assuming 24 bit subnet mask & Ethernet Interfaces)
10.2.3.0 = Routers A & B
10.5.4.0 = Routers A & D
10.2.4.0 = Routers B & C
10.6.2.0 = Routers C & D
RouterA's directly connected routes
(shown in routing table, but not configured):
C 10.2.3.0 255.255.255.0 Ethernet0/0
C 10.5.4.0 255.255.255.0 Ethernet0/1
RouterA's static Routes:
ip route 10.2.4.0 225.255.255.0 Ethernet0/0
ip route 10.6.2.0 255.255.255.0 Ethernet0/1
RouterB's directly connected routes
C 10.2.4.0 255.255.255.0 Ethernet0/0
C 10.2.3.0 255.255.255.0 Ethernet0/1
RouterB's static Routes:
ip route 10.6.2.0 225.255.255.0 Ethernet0/0
ip route 10.5.4.0 255.255.255.0 Ethernet0/1
RouterC's directly connected routes
C 10.6,2.0 255.255.255.0 Ethernet0/0
C 10.2.4.0 255.255.255.0 Ethernet 0/1
RouterC's static Routes:
ip route 10.5.4.0 225.255.255.0 Ethernet0/0
ip route 10.2.3.0 255.255.255.0 Ethernet0/1
RouterD's directly connected routes
C 10.5.4.0 255.255.255.0 Ethernet0/0
C 10.6.2.0 255.255.255.0 Ethernet 0/1
RouterD's static Routes:
ip route 10.2.3.0 225.255.255.0 Ethernet0/0
ip route 10.2.4.0 255.255.255.0 Ethernet0/1
I highly recommend a routing protocol, unless this is an excercise in static
routes. Use the following config commands on all routers, for RIP II:
router rip
network 10.0.0.0
version 2
For EIGRP:
router eigrp 1
network 10.0.0.0
For OSPF:
router ospf 1
network 10.0.0.0 0.255.255.255 area 0
Again, use the same configuration on each router. The end result is the
same, and it's much easier (and dynamic).
Hope this helps...

Subject: routing question
Guys,
I need some help with the following scenario:
4 routers with 2 interfaces each 0/0 and 0/1 and all of them need to talk to
one another
ip addresses:
0/0 0/1
10.2.3.1 10.5.4.1
10.2.4.1 10.2.3.2
10.6.2.1 10.2.4.2
10.5.4.2 10.6.2.2
I need help figuring out how the static routes would be configured.....
Thanks in advance.....
Nate
P.S. This question is for an IPv6 project
