    Thank you all for viewing my message. My company is trying to
    implement Private IP over a point to point frame relay. We have 2
    routers(1 gateway and 1 FR PIP) in local office and 2 routers(same as
    local) at the remote office. The PIP routers were just added. Our
    situation is that the PIP router in our office can talk to the PIP
    router at our remote office, but our network cannot communicate with
    each other. I'm sure that it's a routing table issue, I have done
    some research into it, but I don't know how to fix it. If any one can
    help that would be great. Here is our topology.

    local - Cisco RT 1 (gateway) Cisco RT 2 FR PIP
    ethernet 192.168.1.254 192.168.1.2
    Frame Relay 206.133.11.35 -

    remote - Cisco RT1 (Gateway) Cisco RT 2 FR PIP
    ethernet 192.168.2.254 192.168.2.20
    Frame Relay 65.250.21.65

    Routing Table
    Local Cisco RT2 FR PIP
    2 connected interfaces
    192.168.1.2 eth0/0
    206.133.11.35 serial0/0.100
    65.250.21.64 via 206.133.11.34 through serial0/0.100
    RIP is on 206.133.11.0

    Remote Cisco RT2 FR PIP
    2 connected interfaces
    192.168.2.20 eth0/0
    65.250.21.65 serial0/0.100
    206.133.11.34 via 65.250.21.64 through serial0/0.100
    RIP is on 65.250.21.0


    I can ping local Eth of RT2, but not the serial IP
    I can not ping remote eth or serial
    from local RT2 I can ping any local IP, self eth IP, self serial IP,
    and Remote serial IP, but not remote LAN or remote RT2 eth IP
    telnet into remote RT2 I can ping remote IP, remote self eth IP,
    remote serial IP, local serial IP, but not local eth IP or local LAN.

    Do I need to add more static routes?
    Do I need to change the routing table on the gateway routers also?
    And how do I do that?

    Thanks for all your help,

    Paul

    The Frame Relay PVC should be a single subnet, so both routers should
    have addresses in the same subnet.

    RIP won't work between the routers if they're not on a common subnet.

    both PIP routers are using 255.255.255.252 subnet and they can talk to each other

    Why have you got 206.133.11.25 at one end and 62.250.21.65 at the other? If
    it's point-point why not have one or the other? Are you using secondary
    addresses?

    Maybe best posting parts of your config

    I assume from the IP addresses of the FR links (and from previous
    comments) that the FR network "breaks out" into some intermediate
    network somewhere.

    The two private networks can't talk because neither appears in the
    routing table at the remote end, so you were correct in your
    assumption that it is a routing table issue. The first question that I
    have is :- are private address ranges allowed across your FR network?

    The 206.133.11.25 255.255.255.252 and the 63.250.21.65
    255.255.255.252 were IP's given to us by the ISP(MCI). Those 2
    routers CAN talk to each other,

    I can ping local Eth of RT2 from a LAN computer, but not the serial IP

    How is an ISP involved? Your original post said that this was a frame
    relay connection between your two sites. Are they actually frame relay
    connections to the ISP POPs?
