[quagga-users 14565] Trouble distributing 0.0.0.0/1 route through RIP

We have two routers connecting a LAN to two upstream ISP's. We'd like to
distribute default routes into RIP in such away that LAN user's prefer a
specific router.

 

On ROUTER-1 (the preferred router) we have:

 

    router rip

        version 2

        network eth3

        redistribute static

    ! Default to preferred upstream

    ip route 0.0.0.0/1 192.168.1.1

    ip route 128.0.0.0/1 192.168.1.1

 

On ROUTER-2 we have:

 

    router rip

        version 2

        network eth3

        redistribute static

    ! Default to backup upstream

    ip route 0.0.0.0/0 192.168.2.1

 

Using tcpdump, we can confirm that ROUTER-1 is advertising the two routes
into RIP. But examining the routing table on ROUTER-2 shows the following

 

    ROUTER-2> show ip route

    Codes: K - kernel route, C - connected, S - static, R - RIP

           O - OSPF, I - IS-IS, B - BGP, A - Babel

           > - selected route, * - FIB route

 

    S>* 0.0.0.0/0 [1/0] via 192.168.2.1, eth2

    R>* 128.0.0.0/1 [120/2] via 192.168.3.2, eth3, 00:00:03

 

It appears ROUTER-2 accepted 128.0.0.0/1 but did not accept 0.0.0.0/1. Can
anyone shed light on why this might be ?

 

If it's relevant, we are running Debian Jessie, Quagga 0.99.23.1

 

Thanks

Jim C.
