iBGP over redundant link/ospf and dummy interface

[Arjan Filius]

Hello,

thanks very much for your quick response.

2 iBGP sessions over 2 redundant links are working now, need to test 
failover situation.


just to make it 100% clear, what i understand is not to use the ospf 
failover because iBGP won't work (yet) with the dynamic (ospf) route.
Or it it just  an inconvenience, and wil it work with perhaps a predefined 
route "tick" ?

Regards,

Arjan Filius
