Simple RIP-based topology getting TTL expired in transit / routing ping-pong



  • This one is a doozy, and I've spent all morning attempting to fix with no success. It was working prior to the weekend, and I've confirmed that no one other than myself made changes.

    Very simple setup with the following:
                                (VLAN 100)

    /–---- MANAGE VLAN  (250)
    [FW01]–--[AP]–--[STATION]–--[FW02]
                                                            \–----- Workstation VLAN (20)

    All wireless devices are sitting on VLAN 100.
    FW01's VLAN100 interface is sitting on 10.x.100.1
    FW02's VLAN100 interface is sitting on 10.x.100.2
    [AP] and [STATION] are set to bridge the wireless and wired interfaces.
    FW02's Manage VLAN is set to 10.x.250.1
    FW02's Manage VLAN is set to 10.x.20.1
    FW01 and FW02 are set to have RIPv1 turned on the VLAN100 interfaces.
    All firewalls are set to pass any from any to any, any protocol. (Open wide until I can confirm the topology is working).

    What is happening is that clients on the left of FW01 cannot reach either the 250VLAN or the 20VLAN. When you ping any IP in those subnets, I get a TTL expired in transit message from ping.

    It appears that FW02 is replying back to the request to route saying that any host on VLAN250 or VLAN20 is handled by 10.x.100.1 - FW01. So the packet hits back to FW01, which then forwards to FW02, and it loops.

    What is bizzarre about this is that this holds true for even the IP's of the FW02 interfaces themselves! Ping 10.x.250.1 and you get TTL errors. Ping 10.x.20.1 and you get TTL errors- even though these are interfaces on the FW itself.

    I reloaded FW02 from scratch and rebuilt the interfaces, only to get the same behavior. It's as if the firewall doesn't even know how to route to it's own interfaces, or doesn't know what it has.

    There are no static routes, no additional gateways, etc.

    See below for results from PING / Traceroute:
