Chapter 20 Configuring UDE and UDLR
Configuring a Receive-Only Tunnel Interface for a UDE Send-Only Port
To configure a receive-only tunnel interface for a UDE send-only port, perform this task:
Command
Step 1
Router(config)# interface tunnel number
Step 2
Router(config-if)# tunnel udlr receive-only
ude_send_only_port
Step 3
Router(config-if)# ip address ipv4_address
Step 4
Router(config-if)# tunnel source
{ipv4_address | type number}
Step 5
Router(config-if)# tunnel destination
{hostname | ipv4_address}
