[OLSR-users] Assertion `metric_counter' failed

Tue May 17 16:05:08 CEST 2005

Hi

I am also getting the assertion failed error when the IPv6 address of the node changes. I have 10 nodes . I start the nodes with preconfigured global Ipv6 address and then change the IPv6 address on certain nodes (say 5 nodes). when updating the routing table...the assertion failed error happens. 

I tried replacing the olsr_delete_routes_from_kernel() in the process_routes.c with the simple link list traverse and delete (similar to the one use upto 0.4.8 olsr_delete_routes_from_kernel()). Then it works fine (assertion failed error doesnt happen).

Also when the IPv6 address changes, the routing table is not formed properly. I analysing whats happening on when the IPv6 address changes and i will post a more detailed msg later. Hopefully some changes in the ifnet.c program will do

Hi Philippe,

Could you provide the output with debug level 3 from when the assertion
fails?
