Dear colleagues, I have new question about Subscriber redundancy group.
ASR 9006, RSP440-SE, iOS-XR Version 6.4.2, 32-bit.
What is the maximum number of entries in state-control-route directive I can use ? I read this topic:
"A maximum of 30 state control routes can be added in each subscriber redundancy group (SRG), with a limit of 10 state control routes for each route type. That is, user can have a maximum 10 IPv4 routes, 10 IANA routes and 10 IAPD routes in each SRG. In these 30 routes, user can have routes in either the default or the non-default VRF"
But i have more that 30 entries in my running-config and that is OK: SRG works normally.

hi sergey, it is more a testing limit,
I see your ranges are quite disjoint and not easy to summarize, but if they can be summarized, I would recommend to do so.
alternatively, you can use the null route option with object tracking enabled on them to redistribute these static routes, it is a bit less user friendly since you need the rpl to exclude other possible static routes you may not want to redistribute, where as the subscrbier state control route give you a natural tracked semi static route of the subscriber kind with a tag that is easier to trap through RPL without much extra config of prefix lists etc.

Thank you ,Xander. I'll use non-summarized routes until we migrate to S-C-tag subscriber termination and /32 mask per subscriber.
