Option: Configuring Static ARP on the Ethernet Neighbor Instead of Proxy ARP

If you do not use the proxy statement in the Ethernet TCC and extended VLAN TCC encapsulation hierarchies shown earlier, you must use another method to allow ARP to continue to function. To retain the functionality of ARP for Ethernet networks, you must configure static ARP on the Ethernet neighbor. Use of static ARP assumes that you have already configured the remote statement on the TCC router (see Configuring Ethernet Encapsulation with Remote and Proxy ARP Addresses and Configuring Extended VLAN Encapsulation with Remote and Proxy ARP Addresses).

You configure the arp statement on the Ethernet neighbor at the [edit interfaces interface-number unit unit-number family inet address ip-address] hierarchy level. Your static ARP statement must contain the IP address of the non-Ethernet neighbor on the opposite side of the TCC router and the Ethernet interface MAC address of the TCC router. This static ARP configuration enables return path ARP functionality and complements the remote statement previously set on the TCC router.

In Figure 68, you would configure an ARP statement on the fe-0/0/0 interface of Router C. The ARP statement would contain the IP address for interface so-0/1/0.600 on Router A and the MAC address of the fe-1/0/0 interface of Router B.

Configure static ARP on an Ethernet neighbor at the [edit interfaces interface-name unit unit-number family inet address ip-address] hierarchy level.
