Hi I'm looking for aggregation devices (access switches aggregation). I need to aggregate around 170 access switches. Each switch need to be connected to two core/aggregation devices using mLAG. There are few sites, and every site have around 150-170 access switches.
Requirements: - 4 * 48 linecards, 10GE SFP+ ports - Routing: BGP + ISIS - 12 x 100G ports for inter-site connectivity - MACsec on 10G and 100G - Interconnection between sites: Pure-L3, but would like to have ability to extend L2 VLANs between sites (using EVPN or MPLS) I considered few platforms: - Catalyst 9600 - Nexus 9500 - NCS 5508 NCS a bit too expensive. Probably will go for Catalyst or Nexus. In terms of reliability which solution should I use ? Is Stack-Wise Virtual similar to VSS which we had on 6500/6800 ? Can I have different software version on each core/aggregation device ? (this can provide uninterrupted upgrade with mLAG) Rob _______________________________________________ cisco-nsp mailing list email@example.com https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
