Have the situation where i need to setup a meta router on a RB750 for the client to configure their NAT/Firewall seperately from the main router (which is doing ospf for routed subnet with redundant connections to 2 differnt points in the network). Been trying with 4.2 and keep getting 100% cpu and loosing connection, then afer a while i can reconnect but still have 100% cpu. Disable metarouter and cpu drops to minimum 0%-5%. Thinking i may have to upgrade to one of the RB450G to do that. It's a really basic setup, i should have enough ram to do one metarouter.
