TYPE Legend: I=Indirect Route, D=Direct Route, A=Alternative Route,

B=Best Route,E=Ecmp Route, U=Unresolved Route, N=Not in HW

Paths shown with the letter E in the TYPE column are designated equal-cost

paths. In this example, two routes to IP address 10.1.40.0 and two routes to

IP address 10.1.30.0 are displayed.

Displaying global ECMP conﬁguration

To conﬁrm global ECMP conﬁguration, use the show ecmp command. A

sample output from this command is displayed below:

IP routing conﬁguration using the Java Device Manager

This section describes the procedures for IP routing conﬁguration using the

Java Device Manager (JDM).

Layer 3 routable VLANs

The Nortel Ethernet Routing Switch 5500 Series are Layer 3 (L3) switches.

This means that a regular L2 VLAN becomes a routable L3 VLAN if an

IP address and MAC address are attached to the VLAN. When routing is

enabled in L3 mode, every L3 VLAN is capable of routing as well as carrying

the management trafﬁc. The user can use any L3 VLAN instead of the

Management VLAN to manage the switch.

This section covers the functionality in the Java Device Manager used to

make Layer 3 Routable VLANs possible.
