In order to enable and configure layer 3 routing on MS switches, a layer 3 capable switch is required.
| Model | Layer 3 Interfaces | Routes | Routed Clients | Features |
| MS210 | 16 | 16 static routes | 4096 | Static Routing
DHCP Relay |
| MS225 | 16 | 16 static routes | 4096 | |
| MS250 | 256 | 1024* (256 static routes) | 4096 | Static Routing
OSPFv2 DHCP Server + Relay Warm Spare (VRRP) Multicast Routing (PIM-SM) |
| MS350 | 256 | (256 static routes)
16384* (MS350-24X, 256 static routes) |
96k
512k (MS350-24X) |
|
| MS355 | 256 | 16384* (256 static routes) | 68k | |
| MS410 | 256 | 8192 (256 static routes) | 96k | |
| MS425 | 256 | 16384* (256 static routes) | 112k | |
| MS450 | 256 | 16384* (256 static routes) | 68k |
*In order to protect hardware TCAM resources from exhaustion, the following limitations are enforced on the number of dynamically (OSPF) learned routes for certain platforms:
MS250: 900
MS350, MS355, MS425, MS450: 15000
If the limit is reached, routes will be rejected indiscriminately and may result in erratic routing behavior. To minimize the impact of this, the default route will not be affected by the limit and will be accepted regardless.
