Trying to figure out the IP routing here


7206  <---point to point T1 ----> CISCO 1720  <--->  Wireless Transmitter   <-----> Wireless receiver   <----> CISCO router

Block of IPs used are *.*.*.96  /29
and *.*.*.64 /28

My configuration


serial 5
ip address

ip route *.*.*.96 serial 5

serial 0
ip address

fastethernet 0
ip address *.*.*.97

ip route





CISCO router:

serial 0
ip address *.*.*.100

Fastethernet 0
ip address *.*.*.64

What router I need to add in my 7206 so that computers connected to *.*.*.64 network can access the internet..

    With all those routers the easiest thing to do probably would be to configure EIGRP on all of them. Then they’d automatically pass the needed routing information between them, and all you would need to do is put the one route into the 7206 and away you’d go.  

    router eigrp 1
     redistribute connected
     redistribute static
     no auto-summary

    For the time being , Can I still be able to add a static route in the 7206 or the 1720 to get the traffic out from .64 network ?

    I did these and it seems to work

    on 7206

    ip route *.*.*.64 serial 5

    on 1720  did this

    ip route *.*.*.64 fastethernet0

    Yes you can, all the routers from the far end should have a route pointing to the router that is the next hop. Far end router to > 1720 and 1720 to > 7206. Then you need to add to the 7200 all the subnets in the daisy chain pointing to the 1720 *.*.*.96  /29
    and *.*.*.64 /28 > 1720, then on the 1720 a route to the far end router of *.*.*.64 > last router. But it’s easer to just use EIGRP and let them do it for you, espeaclly if you add more blocks in later since the routers will learn them on their own.


    ip route *.*.*.96  /29
    ip route *.*.*.64 /28


    ip route 0/0
    ip router *.*.*.64 /28 last router

    last router

    ip route 0/0 1720

    The wireless section is a bit of red herring I think, the layer 3 network actually looks like this


    The 7200 needs a route to the *.*.*.97 network and the *.*.*.64 that runs off the far end.

    The 1720 needs a default route to the 7200 and a route to the Cisco's *.*.*.64/28

    The Cisco needs a default route out the 7200 via the 1720.

    I saw from your config that the Cisco seems to have the network address configured on the interface, and not a host, might be better to set it as .65

    Hope that helps

    the routes that I had mentioned in my last comment (before this) did the work.   Thanks for mentioning your suggestion.
