[Xorp-users] error with XRLs

[Atanu Ghosh]

Hi,

If you choose to start the processes yourself you will need to start RIB
(xorp_rib) and FEA (xorp_fea) process, otherwise BGP will not allow
peer information to be added.

Use xorp_fea_dummy if you don't want routes to get into the kernel.

RIB - Routing Information Base
FEA - Forwarding Engine Abstraction

    Pavlin> Jeff,

    Pavlin> The problem is that you need to have a running XORP finder
    Pavlin> if you use XRLs. For that you have two options:

    Pavlin> 1. Add a rtrmgr template to etc/templates/your_protocol.tp
    Pavlin> that will contain the rtrmgr template how to configure your
    Pavlin> protocol, the XRLs sent to your protocol to configure it,
    Pavlin> etc.  Then, when you run xorp_rtrmgr, it will start the XORP
    Pavlin> finder, your protocol, etc and everything else that is
    Pavlin> needed.

    Pavlin> 2. Start libxipc/xorp_finder by hand before starting your
    Pavlin> protocol.

    Pavlin> Option (2) is simpler during initial development testings
    Pavlin> until you have something stable and running.

    Pavlin> Also, please note that you cannot have more than one finder
    Pavlin> on the same machine. E.g., if you have started a XORP router
    Pavlin> (which will be running a finder internally), then you cannot
    Pavlin> start xorp_finder by hand. If, say, you need other XORP
    Pavlin> components as well (say, fea, rib, bgp, etc), then you can
    Pavlin> start each of them by hand in the appropriate order. E.g.,
    Pavlin> xorp_finder, xorp_fea, xorp_rib, xorp_bgp, etc...

    Pavlin> Regards, Pavlin
