    I am looking for the maximum number of routes an MX480 can have in its route table?  I am supporting a client with an MX480 that has just over 1.5mill BGP routes in its table.  We lost one of its primary DIA links which provides a full internet routing table plus some vrfs for VPLS.  When the link flapped and protocols subsequently attempted to re-converge we received the following log message, with latency across the upstream network for a few minutes.

     

    kernel: rt_pfe_veto: Memory usage of M_RTNEXTHOP type = (0) Max size possible for  M_RTNEXTHOP type = (16704245760) Current delayed unref = (40000) Max delayed unref on this platform = (40000) Current delayed weight unref = (40000) Max delayed weight unref on this platform= (400000) curproc = rpd

    there is no hard limit, it depends on installed hardware (RE / FPC type) and configuration. Message you see is just notification.

    Router is configured w/multiple upstream DIA providers w/full BGP tables, mpls/vpls and 1.5mil routes in BGP table alone.

    with these RE and FPC type , it apper limit will be around at 5m routes in FIB. Rib size is much bigger .
