Procedure 18-2.6: Configure IP routing

- Overview

Use this procedure to configure default and/or static IP routes used for MLPPP.

The VLNC60/61/62 provides the ability to configure static IP routes, including a default route. The default route can be used to forward all incoming packets to the gateway router. Static routes could be used to forward specific IP destinations to nexthop IP addresses.

This procedure assumes that the VLNC60/61/62 has been previously installed.

Refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide, for help on using CLI commands.

Step
 
1

Login to the VLNC60/61/62.

Result:

The User EXEC prompt [(ALU switching)>] displays.

2

From the User EXEC prompt, enter enable to enter the Privileged EXEC mode.

From the Privileged EXEC prompt, enter configure to enter the Global Config mode.

3

Configure IP static routes.

From the Global Config mode, enter ip route <destination ip address> <mask> <nexthop ip address> where:

  • destination ip address - destination IP address

  • mask - subnet mask address

  • nexthop ip address - nexthop address

On an VLNC60/61/62 circuit pack, an explicit static IP route is required for destination addresses on same subnet as the IP address on Ethernet port.

Example: (ALU Switching)(Config)# ip route 152.148.1.1 255.255.255.0 1.1.1.10 .

4

Configure IP default routes.

From the Global Config mode, enter ip route 0.0.0.0 0.0.0.0 <nexthop ip address> where nexthop ip address is the nexthop IP address.

Example: (ALU Switching)(Config)# ip route 0.0.0.0 0.0.0.0 255.255.255.0 1.1.1.10 .

5

Enable routing on the global level.

Example: (ALU Switching)(Config)# ip routing.

6

Configure static ARP, if required. This is optional since dynamic ARP exists.

Example: (ALU-Switching) (Config) # arp 100.100.100.1 00:11:22:33:44:55.
