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:
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:
In the following UDE and UDLR sample configuration:
• 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.
