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 }
Configuring a Send-Only Tunnel Interface for a UDE Receive-Only Port
To configure a send-only tunnel interface for a UDE receive-only port, perform this task:
Command
Step 1
Router(config)# interface tunnel number
Step 2
Router(config-if)# tunnel udlr send-only
ude_receive_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 }
Step 6
Router(config-if)# tunnel udlr

In the following UDE and UDLR sample configuration:
•
•
OL-4266-08
On Router A:
–
Open Shortest Path First (OSPF) and PIM are configured.
–
10 Gigabit Ethernet port 1/1 is a send-only UDE port.
The UDLR back-channel tunnel is configured as receive only and is associated with 10 Gigabit
–
Ethernet port 1/1.
On Router B:
–
OSPF and PIM are configured.
10 Gigabit Ethernet port 1/2 is a receive-only UDE port.
–
The UDLR back-channel tunnel is configured as send-only and is associated with 10 Gigabit
–
Ethernet port 1/2.
ARP and NHRP are enabled.
