In XR in general we support restricting routes installed in the FIB using table-policy at various locations, but it's done across all NPUs. This specific feature mixing hi/lo FIB line cards adds another knob to tag certain routes as "external" so we can determine which prefixes to install on cards with only external TCAM.
The normal table-policy command is supported on NCS540, some use them as dedicated RRs. There is a 16 (newer N540-ACC-SYS) and 32 GB (24Z8Q2C-SYS) version of the 540.

There’s caveat at the bottom of that article that says it’s not supported on J-based FFF pizza boxes. I wonder why? I wonder if that applies to Qumran-AX a’la NCS540 too? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
