Maximum path in OSPF in ASR9912/9922

Hi All,

 

I want to know, by default how many paths would ospf consider for ECMP in ASR9912 or IOS-XR platforms and how many maximum paths it can take for ECMP? 

I have checked the device and it gives an option to go upto 64 but some of the documents says it can perform load balancing to 32 paths only.

 

Appreciate the help here..!!!

 

Regards,

Anuj

64/32 is on by default, I am not aware of a command to limit or specify the number of ECMP paths in CEF, its just set to the maximum at all times.

64 path ECMP came in 5.3.0, before that it was 32.

Thanks, but if I don't want to specify the number of maximum links for ECMP, what is the default value for that?
