I presume this is supported in IOS-XR but just making sure. A network across the country is split up into multiple regions. Each region housing two RRs where the local region clients peer with them. Instead of full meshing all of the regional RR consider a tiered topology. 3-4 of the regional RR are designated Super-RR where they full mesh with each other on a global cluster ID. The rest of the regional RR peer with each of the Super-RR and with each other for regions with no super-RR.
The Super-RR areconfigured for the global cluster ID The Regional-RR are configured for the regional cluster ID The Super-RR also peer with the regional clients on a per neighbor cluster ID basis for the local region (set for the Regional cluster ID) The Regional-RR peer with the Super RR on a per neighbor cluster ID (set for the Global cluster ID) The Super-RR end up straddling the fence between the global cluster ID and the regional cluster ID The redundant Regional RR also end up straddling the fence between the global cluster ID and the regional cluster ID but it's main purpose is to be a redundant RR within the region The local region clients peer with the Super-RR in that region and also with the redundant regional RR. Is this feasible/doable with MCID? _______________________________________________ cisco-nsp mailing list firstname.lastname@example.org https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
