How to manage convergence - HSRP with Multicast
Say I am running Multicast in parallel to HSRP or VRRP. My HSRP Primary device is also PIM DR (Higher Pri). When PRI path goes down, the traffic falls back to backup path with HSRP, But PIM take times to converge. Later when Primary Link comes up, PIM again takes lot of time to converge considering it would wait for 105 secs (PIM HOLDDOWN).
Now part of solution could be using HSRP aware PIM but my client per say is running old IOS.
I am unable to find " ip pim hello-interval" in given IOS too though I found this command only in Nexus Multicast command ref but not IOS command ref.
How would you fix it ?
