Your CCR platforms are already rapidly approaching Carrier Grade hardware quality, great work Mikrotik
The only things I can think of for RouterBoard are:
- Hot swap power supplies
- Hot swap fans
- Wire speed forwarding on 10gigabit models
RouterOS still need some improvement, from the top of my head:
* MPLS Fast Re-Route
* Better SNMP implementation, BGP4 MIB, SNMP traps for all state changes/thresholds e.g. Trap on high CPU temp, Trap on BGP peer state change, Trap on interface state change, trap on OSPF state changes.
* More verbose audit trail. Log all configuration changes including the commands typed with the username to Syslog
* Feature and stability fixes to OSPF and OSPFv3
* Improved visibility of routing, e.g. view advertised routes, received routes on a per-peer basis, view all L2VPN/L3VPN info (RT) when routes are printed.
* VRF improvements. Allow to run RouterOS services (Telnet/Winbox/Webfig/SSH/API/PPTP/SSTP) in a VRF, allow RIPv2 as PE-CE protocol, Allow "ip filter" from->to routing tables (e.g. allow more granular filtering on inter-vrf traffic), Allow specification of VRF in RADIUS responses for DHCP and PPP.
* Follow internet standards closely (e.g. RFC's) and update existing RouterOS components to follow current standards e.g. DHCP Radius dictionaries.
not really a carrier feature, but a enterprise/service provider feature:
* VXLAN support (including multicast)
and half of those are probably fixed in RouterOS 7/New Routing....
