switching modules (see CSCdt27074 in the “Resolved General Caveats in Release 12.1(13)E”

section on page 249.)

• Route Processor Redundancy Plus (RPR+) redundancy—For more information, go to this URL:

Note Release 12.1(13)E and later releases allow configuration of 4,096 Layer 3 VLAN interfaces.

We recommend that you configure a combined total of no more than 2,000 Layer 3 VLAN

Engine 1. We recommend that you configure a combined total of no more than 1,000 Layer 3

VLAN interfaces and Layer 3 ports on an MSFC.
