Differences between RB with multiple switch chips

What is difference in configuration on these CRSes? Can I do switching and VLAN Filtering in the same way I'm doing on CRS with single switch chip (can I ignore fact, that some ports is on different switch chip than others)?

I'm not aware of any CRS products which have multiple switch chips. There are other devices (RB1100/RB2011/RB3011/RB4011) which do - none of these support hardware offload with VLAN-aware bridges, and there are other limitations

You right, my mistake, that's not CRSes (I corrected the title).
When I writing about VLAN Filtering, I meant filtering in Switch Chip, not Bridge VLAN Filtering

Switch chip vlan filtering is obviously limited to single chip. Inter-chip communication passes CPU where one can use bridge (in it's non-vlan configuration) to merge multiple ports. However, making configuration on both switch chips consistent is router admin's responsibility, ROS doesn't enforce it in any (ever so slight) way.
