Re: [LISPmob-users] LISPmob router on Ubuntu

Hi Carole,

I think that the problem is that the router is sending the controlmessages through eth1 interface. If you could check using wireshark ....May be in a future we will add a control interface, meanwhile I thinkthat if you add this to de configuration file it could work.



database-mapping {
         eid-prefix     = 1.1.1.0/30
         interface      = eth0

priority_v4 = 2 # Priority of IPv4 locatorof the interface eth0 for this EIDweight_v4 = 100 # Weight of IPv4 locator ofthe interface eth0 for this EIDpriority_v6 = 2 # Priority of IPv6 locatorof the interface eth0 for this EIDweight_v6 = 100 # Weight of IPv6 locator ofthe interface eth0 for this EID

}


database-mapping {
         eid-prefix     = 1.1.1.0/30
         interface      = eth1

priority_v4 = 1 # Priority of IPv4 locatorof the interface eth0 for this EIDweight_v4 = 100 # Weight of IPv4 locator ofthe interface eth0 for this EIDpriority_v6 = 1 # Priority of IPv6 locatorof the interface eth0 for this EIDweight_v6 = 100 # Weight of IPv6 locator ofthe interface eth0 for this EID

Order is important. When LISPmob selects the default interface, it willuse the first interface UP: eth0When LISPmob sends data traffic, it will use priority and weight. Asinterface eth1 is preferable to eth0, it will use eth1 to send traffic


Let me know if it works.

Regards

Albert

If I understood correctly, the problem is in the PiTR functionality.Do you have configured in the PxTR the database mapping of your EIDs?To implement the PiTR functionality we add a route into the routingtable to send all traffic whose destination is an EID (configured inthe configuration file as a database mapping) into the tun interface.If you already have this configured, then I will need you to send methe logs of the PxTR (level 3), the configuration file (removing thepassword) and the routing information: ip r, ip a , ip rule.


Best regards

Albert
