We have a topology in the Lab that is based on CISCO 7609 that are connected in between to switches of other vendors.
7609 is configured with BFD and PIM-SSM,OSPF.
We tested the topology backup in fiber cut scenarios and everything was ok.
We faced a problem when we powered of and on the switch that wa sconnected to one of the 7609 at the leaf of the multicast.
when we powered of the switch the traffic switched to protection quickly.
However when we powered it on we faced and outage of 10 seconds.
The question is what is teh exact process when a switch comes up and so the 7609 detect that the link is up.
what is the process of teh BFD in reconnect ,how long does he wait in order to trigger other protocols, only ib link up or does he need to nehotiate?
Does PIM is triggered by BFD.
We tried the routing protocol with OSPF and static routing but still we got the same results.
All the BFD and PIM Timers are default
