[Xorp-users] Two XORP instances talk to the same Click

[Yi Wang]

Hello,

I was trying to run two instances of XORP on the same node, one runs 
only OSPF, and the other only runs BGP, and let them both use the same 
Click as the forwarding engine. What I found was, although this 
configuration worked at first (both BGP and OSPF routes show up in the 
Click forwarding table _xorp_rt4), either the BGP process or the OSPF 
process went wrong / died after a while (several minutes to several 
hours). Some of them seem because XrlPFSTCPSender died.

I wonder whether there is actually a way to make this setting (two XORP 
talk to the same Click) work, and if yes, how?

Thank you very much.
Yi
