Network requirements
As shown in Figure 84:
• DLSw operates in LAN-to-LAN mode.
• Configure DLSw on Router A, Router B, and Router C to connect the IBM host with the SNA
host through the Internet.

Configuration procedures
1. Configure Router A:
# Configure interfaces on Router A to make sure that the local DLSw peer 1.1.1.1 and remote
peer 3.3.3.3 can reach each other. (Details not shown.)
# Configure DLSw on Router A.
<RouterA> system-view
[RouterA] dlsw local 1.1.1.1
[RouterA] dlsw remote 3.3.3.3
# Enable DLSw Ethernet redundancy on interface Ethernet 1/0, and configure the multicast
address as 9999-9999-9999 and set the priority to 10 for primary/secondary router election.

[RouterA-Ethernet1/0] dlsw ethernet-backup enable 9999-9999-9999 priority 10
# Enable switch support for DLSw Ethernet redundancy on interface Ethernet 1/0. Set the MAC
address of the local device to 0500-0001-0000, the remote SNA device to 0200-0008-0080,
