I am awaiting delivery of a CRS317-1G-16S+RM and am planning the network restructuring I need to do. The switching side is clear. I am however considering to also use the CPU for my internet routing. I need some PPPOE + NAT for IPv4 and routing of IPv6. The main firewall is my Pfsense cluster that does most of the L3 as well. But because of the cluster setup I need to do the NAT on a router that will know how to send traffic to the CARP address for the cluster. Pfsense cluster does not support CARP/PPPOE on a cluster
Looking at the the routing throughput, I see 1270Mb/sec for all ports. I assume that that means effectively 635 Mbps for a symmetrical connection (up/down). Do I understand it correctly that this means that this is insufficient for a 1Gb fiber connection? Right now I have a 100/60 Mbps connection, so using the CRS as router would be ok. But it would be insufficient for a full 1Gbps, right?
