The L3 HW offload feature are supported on the CRS317-1G-16S+ but not on the CCR2004-1G-12S+2XS. Is there any reason to still use the CCR2004 then if we don't need the 25G ports?
My use case is quite simple:
I have 2 links one with PPPOE, one with a GRE tunnel on it on which i get a 1 /48 IPv6 and a /29 IPv4 using BGP.
I want to have failover between both links on a vlan and beeing able to choose one of the connection to pass a specifc /56 Ipv6 prefix.
I have a DHCP server running on it.
Since we have now IPv6 offload support I am wondering if the CRS317 wouldn't be more efficient than the CCR2004. Thoughts? In which case would use the CCR2004 over the CRS317 ?
