BFD Session Limit - 50 ?

[tonie16]

Good day Everyone,

Hope everybody is safe during this interesting times around Covid-19.

I want to hear if anybody has run into a problem where there seems to be a limit of 50 bfd session on the Nokia 7750 routers?
We have 96 bfd sessions configured, but only 50 seems to be active ?

Kind regards,

"The number of BFD sessions on cpm 0 has exceeded 50, constrained by maxSessionsPerSlot "

Our model is a 7750 SR-c12. It would seem that the limit on 7750 SR-c12 is 50.

You can try offloading BFD to the CPM if it's currently being processed by the IOM.

as lo0 said, the solution is to change the iom hardware to cpm-np base when define the bfd configuration under your particular interface.
