The Nortel Ethernet Routing Switch 5500 Series (E1), running in Layer 2

mode, is conﬁgured with one port-based VLAN and one MultiLink Tr unking

(MLT) group for the aggregate uplink ports. The Nortel Ethernet Routing

Switch 5500 Series switches (R1 and R2) are conﬁgured with backup

master enabled so that both switches can reply to ARP.
